[00:01.580 --> 00:03.840]  All right, so yeah, that's the title of the presentation.
[00:04.540 --> 00:11.700]  When I came up with the idea for this, I thought it's almost like an easy one to say, well, what are the top 10?
[00:12.080 --> 00:13.880]  But there's always going to be some bias in that.
[00:13.960 --> 00:21.340]  And so I needed to come up with some way to say, with some fact-based way, why are these the ones that matter?
[00:21.800 --> 00:23.860]  And that's where the democracy comes in.
[00:23.860 --> 00:28.460]  So I bet everyone in this room is familiar with GitHub.
[00:29.300 --> 00:32.480]  Is there anyone, if they want to raise their hand, that's not familiar with GitHub?
[00:34.020 --> 00:37.080]  Okay, I'm really glad to not see any hands raised.
[00:37.300 --> 00:39.560]  So yeah, I think everyone here is the right audience.
[00:39.800 --> 00:45.940]  So it goes without saying, it's the most popular repository for everything.
[00:46.500 --> 00:48.120]  And there's lots of cool projects.
[00:48.120 --> 00:54.500]  And when you go and search on GitHub, searching matters.
[00:54.900 --> 01:07.660]  And so when I started the journey on this presentation, what I soon discovered was when you do a search for software-defined radio, or SDR, you get drastically different results.
[01:07.660 --> 01:10.080]  And same thing also with amateur radio.
[01:10.280 --> 01:12.120]  As most people know, amateur radio is ham radio.
[01:12.460 --> 01:19.000]  And so this data that I have on the screen right now, this was August 5th.
[01:19.120 --> 01:20.620]  The numbers have actually increased.
[01:20.620 --> 01:24.600]  I think on SDR, it's up to like 10,400 results.
[01:25.320 --> 01:28.500]  And then software-defined radio, I think was like 890 now.
[01:29.400 --> 01:31.780]  But amateur radio and ham radio is roughly about the same.
[01:31.900 --> 01:33.160]  But again, it doesn't really matter.
[01:33.160 --> 01:40.560]  But just to show kind of the scale, you know, if you do a search for SDR, you're going to get a lot more results compared to if you spell it out.
[01:40.640 --> 01:41.960]  And I think we all like shortcuts, right?
[01:42.140 --> 01:43.560]  So no surprise there.
[01:43.920 --> 01:46.640]  And what's funny is there's not really a lot of overlap.
[01:46.840 --> 01:53.420]  And so when you go on Git, you go up to the top and you type in, you click and say, show me what has the most stars.
[01:53.680 --> 01:57.540]  Or maybe some of you want to see what's the most forks or what's been most recently updated.
[01:57.540 --> 02:04.680]  But in this case, I thought, well, if we go by stars, if everyone's logged in and they're voting, that's where the democracy comes in.
[02:04.940 --> 02:07.900]  And so this way, that's a community of everybody in this room and around the world.
[02:08.060 --> 02:12.500]  But ideally, what's going to have the most stars is most likely what's popular or most popular.
[02:12.500 --> 02:15.680]  And that was kind of where I started.
[02:16.140 --> 02:22.960]  But then that kind of took a little weird turn because when we run these searches, I'll use SDR as the example.
[02:23.160 --> 02:29.320]  So hopefully nobody's too color blind here, but the long stripes that are orange, that's the official color.
[02:29.520 --> 02:35.300]  But you can see like things are taking a very different turn here.
[02:35.300 --> 02:44.200]  So looking at the total number of stars, the fact that the number one most ranked SDR app, which I'll get to, has over 11,000 stars.
[02:45.140 --> 02:46.120]  That's pretty crazy.
[02:46.180 --> 02:47.740]  And it drops off from there.
[02:47.880 --> 02:54.600]  But then when we go and compare like SDR to softer defined radio, which is in like a light blue color, gets smaller.
[02:54.800 --> 02:58.960]  And then when we look at ham radio and amateur radio, it's almost like you have to really look close to this.
[02:59.140 --> 03:01.120]  But again, I wanted to try to figure out a way.
[03:01.300 --> 03:02.480]  How do we really look at this?
[03:02.480 --> 03:10.280]  And just because something has the most stars, that might actually not be the most popular or like the most innovative or what's really driving things.
[03:10.400 --> 03:15.320]  And so what I wanted to come up with was a way to figure this out.
[03:15.440 --> 03:18.620]  And so if we added up all those stars, so let's just use SDR as the example.
[03:18.780 --> 03:26.680]  So if we said SDR and softer defined radio, we add up those top 10 applications for each 71,000 plus stars.
[03:27.620 --> 03:30.480]  That's crazy, you know, and that's just the top 10.
[03:32.020 --> 03:38.880]  And on Git, there's various APIs that you can do and you can do all sorts of, you know, clever math and stuff like that.
[03:39.000 --> 03:45.440]  But just at a high level, to give you the context for when you take all the stars for SDR and softer defined radio, 71,000 stars.
[03:45.440 --> 03:49.580]  That makes amateur radio seem like really sad, right?
[03:49.700 --> 03:54.040]  Like in comparison, I think charts do the messaging here.
[03:54.180 --> 03:58.580]  And then for the top 10 amateur radio and ham radio applications, only 9,100 stars.
[03:58.720 --> 04:03.740]  And I thought, well, that seems kind of bad, but there's a lot of positivity in this.
[04:03.900 --> 04:05.340]  And that's what I want to kind of get across.
[04:05.920 --> 04:08.240]  So I came up with something that I call velocity.
[04:08.680 --> 04:13.640]  Out of curiosity, has anyone used the starhistory.com website before?
[04:14.580 --> 04:17.780]  One, one hand or two and three quarters or so?
[04:17.980 --> 04:26.820]  So yeah, so I thought, all right, well, star history is good because basically you can type in the repository and it'll do all the math for you instead of me having to go and do my own APIs.
[04:27.120 --> 04:31.960]  So that was cool because it showed me when a project started and how many stars it has.
[04:31.960 --> 04:35.540]  And it takes little periodic measurements over the span of the project.
[04:35.920 --> 04:43.920]  And as we can see in this green stripe, and some of you might see that this is actually related to the Universal Radio Hacker project.
[04:44.640 --> 04:46.280]  That's how I'm calculating velocity.
[04:46.600 --> 04:54.540]  So basically, all we're doing is we're taking the number of days and the number of stars and dividing them into each other and coming up with a score.
[04:54.740 --> 04:57.020]  And that's how it calculates out these charts.
[04:57.240 --> 04:58.740]  And you could flip things around.
[04:58.740 --> 05:06.120]  And because we all like QR codes, anyone who's seen my presentations in the past here, I'd hope, know that I love QRs.
[05:06.380 --> 05:10.680]  So hopefully a bunch of you are going to scan this QR.
[05:10.940 --> 05:14.740]  What it will bring you to is across those four search terms.
[05:15.260 --> 05:17.800]  So for software-defined radio, what are the top ten?
[05:18.020 --> 05:19.260]  Amateur radio, top ten.
[05:19.380 --> 05:20.480]  Ham radio, top ten, et cetera.
[05:20.700 --> 05:23.120]  We don't have time to go through 40 applications.
[05:23.120 --> 05:24.680]  This will be a long presentation.
[05:24.720 --> 05:26.500]  A good one, but a long presentation.
[05:27.020 --> 05:34.820]  So when you scan this QR code for anyone who's doing this, it's only going to show you the top eight, which is in that box to the left.
[05:35.460 --> 05:38.780]  If you have an API token, which is super easy to set up.
[05:39.200 --> 05:45.580]  If you have an API token, probably some of you have this, but probably not on your smartphones.
[05:46.680 --> 05:50.320]  Just click off the little box that says you need a token and it'll show you the list.
[05:50.460 --> 05:51.960]  So you can click into all of these.
[05:52.420 --> 05:55.820]  The little landing page that I created on one of my ham radio club's websites.
[05:55.820 --> 05:59.040]  It'll show you these charts specific to those four terms.
[05:59.200 --> 06:06.800]  And so hopefully everyone scans this, brings it to the landing page, save it in your history, and you can click back and look at things.
[06:06.940 --> 06:09.340]  Again, I'm only going to look at some of the top, top ones here.
[06:09.540 --> 06:11.640]  But again, there's 40 really cool things.
[06:11.780 --> 06:15.660]  And I like analyzing data and anyone who knows me knows that I like analyzing things.
[06:15.660 --> 06:18.060]  So we're going to really look at the top eight.
[06:18.600 --> 06:24.600]  So the top two in each, plus two others, because again, I don't want to let anyone down that this is a top 10 presentation.
[06:24.600 --> 06:25.480]  So I have 10.
[06:25.680 --> 06:28.960]  But like I said, there's 30 other applications that are not captured.
[06:29.140 --> 06:32.740]  So definitely go to the QR code.
[06:33.080 --> 06:37.480]  And hopefully everyone could I get like a thumbs up and make sure that everyone's decoding it.
[06:37.600 --> 06:37.940]  You're good.
[06:38.080 --> 06:38.440]  All right, sweet.
[06:39.120 --> 06:39.560]  All right.
[06:40.080 --> 06:45.000]  So before we dive into the meat, who I don't know if anyone remembers the ShamWow guy.
[06:45.000 --> 06:47.540]  I was looking for like a clever infomercial kind of guy.
[06:47.760 --> 06:49.340]  So this is like the infomercial.
[06:49.560 --> 06:59.900]  You know what I really try to encourage when I when I give like radio related presentations, which is a topic that I'm very passionate about, is learn more about this stuff.
[07:00.100 --> 07:01.700]  It's not just about amateur radio.
[07:02.320 --> 07:03.700]  SDR is not about amateur radio.
[07:04.080 --> 07:06.940]  There's folks like Moon, who has an SDR that I just learned.
[07:07.660 --> 07:10.500]  Don't know what they're doing with the SDR yet.
[07:10.660 --> 07:12.720]  I'm sure I'll find out in Q&A time.
[07:12.720 --> 07:14.720]  So learn about all this stuff.
[07:14.900 --> 07:17.220]  Most importantly, meet other people into the stuff.
[07:17.360 --> 07:18.960]  I know the last two hopes that I presented.
[07:18.960 --> 07:24.760]  I've met a lot of people and we've stayed in touch because, you know, events like this are really awesome people connectors.
[07:24.960 --> 07:26.280]  And so that's definitely a takeaway.
[07:26.280 --> 07:33.900]  A big shout out to Ed N2XDD, Nicole 82IM and Dan KB6NJU.
[07:34.080 --> 07:37.080]  They're giving a get your ham radio license in one day.
[07:37.460 --> 07:41.080]  And for anyone who feels like they've already trained, they can get their ham radio license.
[07:41.280 --> 07:42.700]  So there's stuff like that going on.
[07:42.840 --> 07:51.700]  So again, hopefully some of the things that I cover here are going to encourage you to either get on the amateur radio path or go further in that path.
[07:51.700 --> 07:52.560]  And so we have that.
[07:52.720 --> 07:55.580]  And then new for this year, kind of weird.
[07:56.160 --> 07:58.560]  Some of you have probably seen some weird yellow signs around.
[07:58.720 --> 07:59.740]  Toilets on the air.
[07:59.900 --> 08:02.360]  This is a clever amateur radio activity.
[08:02.820 --> 08:04.720]  It's safe the way that it's set up.
[08:04.720 --> 08:07.820]  So again, just a kind of a brief infomercial of some things.
[08:08.040 --> 08:11.820]  Look for me at the RF village over across the street here.
[08:11.980 --> 08:15.360]  So if anyone wants to chat afterwards, I'll just be here for the remainder of the day.
[08:15.420 --> 08:24.660]  And there's a lot of my cohorts that are into all this cool radio stuff, as well as the NYC resistor folks at the opposite end of the show hall.
[08:24.780 --> 08:25.700]  So we're doing cool things.
[08:26.840 --> 08:27.820]  So there you go.
[08:27.960 --> 08:29.060]  So, all right, so let's dig in here.
[08:29.260 --> 08:32.340]  So going back to velocity, like I said, stars divided by days.
[08:32.340 --> 08:34.480]  That's how we come up with these velocity.
[08:34.820 --> 08:39.300]  Don't worry, I'm not going to go through this bar chart because this is a light and fun presentation.
[08:39.600 --> 08:48.480]  But going from the top 10 of the highest velocity, the big takeaway here is you can see at the bottom, URH, Universal Radio Hacker.
[08:48.680 --> 08:50.340]  It's almost like a velocity of three.
[08:50.900 --> 08:53.100]  That has been around for a long time as a project.
[08:53.240 --> 08:54.200]  I'll come back to that later.
[08:54.340 --> 09:06.580]  But you can see just for like out of all 40 of these applications across the four search terms, all nine of the 10, those all actually come out of SDR, not software defined radio, SDR.
[09:07.140 --> 09:14.940]  The one that I've highlighted here is the only one that does not come in, and that's one under ham radio.
[09:14.940 --> 09:21.180]  And that's something called KiwiPorP hyphen HT, which I'll cover.
[09:21.440 --> 09:24.320]  But the point here is there's a lot of cool things.
[09:24.440 --> 09:31.880]  And I think it's fair that if people talk about projects and more people vote stars, it creates higher velocity, right?
[09:32.060 --> 09:40.000]  And then when you find out that this is a cool thing and you tell your friends about this, then they want to figure it out and it just drives more engagement.
[09:40.000 --> 09:43.620]  And so that I think is a cool way to kind of look at this.
[09:43.740 --> 09:46.240]  And maybe you might want to even consider applying this to other things.
[09:46.340 --> 09:53.840]  Maybe if you're into AI or, you know, crypto or whatever, you know, different ways that you could use star history to calculate these, what I'm calling velocity.
[09:54.880 --> 10:03.540]  The last thing before I move on is the purple dotted line that connects to one project will not be possible without the other, which I'll come to.
[10:03.540 --> 10:05.400]  So just to kind of share that.
[10:05.520 --> 10:07.220]  And I thought that was really interesting.
[10:07.320 --> 10:12.620]  The fact that there's one that drives another and both are actually in the top ten.
[10:12.800 --> 10:16.360]  And so that actually adds like a little extra weighting for why these are cool.
[10:16.440 --> 10:18.180]  But again, I'll go through these in detail.
[10:19.500 --> 10:20.860]  And here we are.
[10:21.040 --> 10:22.160]  Here is the top eight.
[10:22.360 --> 10:24.160]  Sorry, there's a lot of detail on here.
[10:24.300 --> 10:32.000]  So basically what I decided for this presentation is I'm going to focus on the top two in terms of velocity across all four search terms.
[10:32.000 --> 10:37.220]  And so if we look at amateur radio, we'll be talking about something called Wave Log and then GR Satellites.
[10:37.740 --> 10:50.920]  So after a defined radio, Caribou Light and GQRX, ham radio, KVPORHT and AOIC, not AOC, local politician, and URH and STR++.
[10:51.380 --> 10:59.240]  I thought it was also worth just kind of highlighting that just because something stored high velocity, how many stars overall?
[10:59.240 --> 11:04.440]  And so I have a number in the upper left hand corner of each slide of like how they ranked overall.
[11:04.580 --> 11:09.240]  And again, I'm not trying to rank like who's the best because this is like democracy and there's all of them are really cool.
[11:09.660 --> 11:17.160]  But I thought it was also worth just kind of giving a quick shout out to what was the highest star ranking just to see if the math was off.
[11:17.160 --> 11:26.140]  So like, for example, when we look at amateur radio, Wave Log is first in velocity, but has fifth overall total stars.
[11:26.580 --> 11:30.380]  GR Satellite is the second highest in velocity, but first overall stars.
[11:30.660 --> 11:35.240]  And then there's something called APRS DROID, which is sixth highest velocity, but second most stars.
[11:36.460 --> 11:40.480]  So again, looking at data, I think is really an important thing.
[11:40.640 --> 11:45.200]  And again, that's really the gist of this presentation is how did I come up with this?
[11:45.260 --> 11:49.960]  And again, we're looking at everything based on velocity, not total stars for what I go through here.
[11:51.300 --> 11:52.860]  So here's your last chance.
[11:53.120 --> 11:55.440]  I made this QR code extra, extra, extra big.
[11:55.620 --> 11:58.920]  If you want to go to that repository page, here's your last chance.
[11:58.920 --> 12:05.020]  And if you haven't been able to capture on the small one, here's your chance, but it's going to go to the same of where I've directed.
[12:05.280 --> 12:10.180]  So again, we're going to look at the top eight, two per each, plus two special mentions.
[12:11.020 --> 12:13.140]  And then we'll take some Q&A.
[12:14.060 --> 12:15.880]  And again, toilets on the air.
[12:15.980 --> 12:17.840]  I'm getting a lot of mileage out of the ShamWow guy.
[12:18.520 --> 12:19.780]  Definitely check this out.
[12:19.940 --> 12:21.640]  This QR code goes directly to this.
[12:22.620 --> 12:25.260]  This will make a little bit more sense when I go to the next slide.
[12:25.260 --> 12:41.640]  But when you register or even if you don't register and you want to check this out, you could look at where are these toilets here in the map, the data, the users who's registered, what frequencies they're doing, how many contacts.
[12:41.800 --> 12:43.580]  Like it is like massive data analysis.
[12:43.780 --> 12:48.020]  The NYC resistor and Todd specifically have helped bring this over from Europe.
[12:48.140 --> 12:49.860]  This is not like our original idea.
[12:50.320 --> 12:51.720]  Toilets on the air has been a thing.
[12:51.980 --> 12:54.120]  Hence the website at totawatch.de.
[12:54.120 --> 12:56.620]  So it started in Germany, but this is the first year.
[12:56.720 --> 12:58.240]  And hopefully this continues going forward.
[12:58.360 --> 13:02.420]  So everyone who has like a Baofeng radio, check it out, especially if you're a ham radio.
[13:02.560 --> 13:07.560]  Or if you just want to listen quickly, what activity are we doing?
[13:07.560 --> 13:16.180]  We thought it would just be like people talking back and forth on radio saying, hey, I'm a toilet zero one and you hear me good.
[13:16.420 --> 13:18.380]  And we log it into this application.
[13:18.700 --> 13:28.300]  But what's actually happened since yesterday is there's people holding their cell phones up to their radios and sending what's called slow scan television.
[13:29.580 --> 13:36.680]  And don't worry, nobody's taking weird photos in the toilets outside or in the vicinity of things related or unrelated.
[13:36.920 --> 13:38.700]  But again, keeping it fun.
[13:38.840 --> 13:42.240]  I think it's kind of a neat hack, if you will.
[13:42.380 --> 13:45.020]  So definitely check out totawatch.de.
[13:45.020 --> 13:48.640]  That's where the QR code Mr. ShamWow was pointing to.
[13:49.040 --> 13:51.740]  And hopefully we're not using ShamWows as part of Toda.
[13:52.700 --> 13:53.020]  All right.
[13:53.220 --> 13:54.360]  So here we go.
[13:54.560 --> 13:56.920]  So the first one, and again, these are not like in order.
[13:57.260 --> 14:00.640]  So I just kind of put them in what I thought was just a good talk track.
[14:00.900 --> 14:04.900]  So the first one, this is something that's related to amateur radio, not ham radio.
[14:05.180 --> 14:06.120]  So wave log.
[14:06.420 --> 14:14.560]  So anyone who's been around the amateur radio worlds for a while knows that amateur radio people love to keep track of who they talk to.
[14:14.560 --> 14:21.920]  So this way, nine years later, they can say, hey, Fred in Germany, I spoke to you for three and a half seconds, seven and a half years ago.
[14:22.080 --> 14:24.660]  And we did this on this frequency and the temperature was whatever.
[14:24.860 --> 14:28.680]  You know, amateur radio is all about like data analysis.
[14:28.680 --> 14:32.400]  Or even if they don't data analyze it, it's all about collection, it seems.
[14:32.600 --> 14:34.460]  But this is a really cool project.
[14:34.780 --> 14:40.180]  The fact that this was growing as fast as it is.
[14:40.180 --> 14:45.100]  I largely attribute that to the fact that this is what's known as a forked project.
[14:45.300 --> 14:51.040]  So it actually started life as something called Cloud Log, which currently has the three most amateur stars.
[14:51.320 --> 14:54.720]  But now Wave Log has actually overtaken that in terms of velocity.
[14:54.960 --> 15:04.920]  So not only is there a lot of crossover technology, if anyone's familiar with containers and self-hosted PHP applications and stuff, there's a lot of cool things.
[15:05.220 --> 15:12.100]  And this actually is something, as we see in the right hand corner of the slide, something that actually relates to toilets on the air.
[15:12.780 --> 15:14.280]  So this is kind of neat.
[15:14.460 --> 15:16.220]  It's a lot of good crossover technologies.
[15:16.980 --> 15:22.100]  You can see some of the different keywords over at the left, which is always a good thing to search for.
[15:22.100 --> 15:30.880]  So not only if you're doing a search for amateur radio, if you did a search for something like web app or what's not amateur radio related.
[15:32.000 --> 15:33.000]  Yeah, pretty much.
[15:33.140 --> 15:33.820]  And self-hosted.
[15:34.400 --> 15:35.820]  Yeah, that's pretty much it.
[15:35.900 --> 15:38.860]  But everything else is like an amateur radio kind of related term.
[15:39.000 --> 15:40.420]  So this is a pretty cool project.
[15:40.700 --> 15:43.140]  And it started life in Europe.
[15:43.140 --> 15:51.040]  Those are the call signs for the main developer team, DF2 ET, DJ7NT, HB9, HIL, and LA8AJA.
[15:51.380 --> 15:52.460]  Are any of you present?
[15:53.240 --> 15:53.640]  No?
[15:53.800 --> 15:54.900]  I just figured I'd ask.
[15:55.300 --> 15:58.160]  So yeah, so logging, it's kind of a cool thing.
[15:58.280 --> 16:01.640]  And again, just to show amateur radio is not just about, you know, talking on radio.
[16:01.800 --> 16:02.920]  There's lots of other things.
[16:03.060 --> 16:06.560]  And there's lots of hams that I personally know that do cool things like this.
[16:06.640 --> 16:09.060]  And they never touch a microphone or a Morse code key or anything.
[16:09.200 --> 16:10.220]  They just like doing cool stuff.
[16:10.740 --> 16:11.780]  So that's wave log.
[16:11.780 --> 16:14.060]  And moving on, again, another European ham.
[16:14.220 --> 16:20.480]  He splits personality between Spain and the UK is Danny.
[16:20.940 --> 16:25.180]  And this is a satellite-related project.
[16:25.180 --> 16:29.420]  And this is the second highest in terms of velocity.
[16:29.640 --> 16:32.820]  27th overall in terms of the stars across the 40 that I have.
[16:33.000 --> 16:45.540]  What's neat about this, for anyone who's been around software-defined radio for more than a minute, you probably come across something called GNU Radio, which is, like, super daunting to figure out what is going on.
[16:45.620 --> 16:46.920]  But he makes it easier.
[16:47.100 --> 16:53.200]  So basically, in GNU Radio, he's created a number of workflows, and he's been at this since 2015.
[16:53.200 --> 17:05.980]  So every time that amateur radio communities launch satellites, there's telemetry, which means, like, they're sending down parameters of operational or maybe some images or other data for communications back on the ground.
[17:05.980 --> 17:12.580]  So he has all these projects worked out, built on GNU, and has it in his project.
[17:12.720 --> 17:13.660]  So it's actually pretty easy.
[17:13.760 --> 17:17.660]  It's super well-documented, and it's overall really cool.
[17:17.780 --> 17:22.620]  So I would highly encourage people to check that out if you're looking for, uh-oh, GNU Radio.
[17:22.620 --> 17:23.420]  There it is again.
[17:23.680 --> 17:24.700]  What can you do with it?
[17:24.860 --> 17:26.560]  So you get your SDR.
[17:26.940 --> 17:28.240]  You run this with GNU.
[17:28.960 --> 17:35.280]  Hopefully you have the right antenna, because if you're picking up signals from outer space, you've got to figure that out, which is a topic for a different day.
[17:35.440 --> 17:43.880]  But, again, this is pretty unique that this is a project that's been around for 10 years, and it's ranked up there pretty high in terms of velocity.
[17:43.880 --> 17:50.300]  And in more recent years is where it's got more notoriety compared to when he started this.
[17:50.420 --> 17:53.920]  So I think that's really an amazing accomplishment to stick with a project for this long.
[17:54.840 --> 17:55.180]  All right.
[17:55.280 --> 17:56.800]  Moving to some hardware stuff.
[17:57.400 --> 17:58.620]  Here's something that's SDR.
[17:59.040 --> 18:00.540]  This is called a Caribou Lite.
[18:01.040 --> 18:02.740]  I don't know if anyone's come across this.
[18:02.940 --> 18:08.580]  Probably if you're going from like a $30 SDR receiver, you then probably think, how do you transmit?
[18:08.920 --> 18:11.880]  Well, this is like one of the lower cost ways to do this.
[18:11.880 --> 18:12.820]  There's two versions.
[18:12.980 --> 18:19.840]  There's one that goes from zero to six gigahertz, and then another one that does 2.4 gigahertz, like Wi-Fi, and then sub-gigahertz.
[18:19.900 --> 18:26.180]  So for anyone who's into like 900 megahertz or ISM communications, there's one that's roughly about half the price.
[18:26.340 --> 18:30.000]  But basically, the way that this works is you attach it to a Raspberry Pi Zero.
[18:30.480 --> 18:38.060]  You could attach it to like a regular full-size Raspberry Pi, although there's some dependencies that are in the works for the Raspberry Pi 5.
[18:38.660 --> 18:42.300]  But for the most part, running this connected to a Raspberry Pi 2.
[18:42.420 --> 18:43.400]  Now, what would you do with this?
[18:43.680 --> 18:49.140]  Well, let's say if you want to make some kind of crazy like IoT transmitter or receiver or data aggregator or whatever.
[18:49.500 --> 18:53.780]  The point is, this project is not just hardware as open-source on Git.
[18:53.940 --> 18:58.700]  It's also open-source software, and this would work across a lot of other projects.
[18:58.700 --> 19:00.200]  And so this is kind of unique.
[19:00.400 --> 19:02.080]  This is 11th overall stars.
[19:02.300 --> 19:08.760]  It's the fastest-growing one under software-defined radio, not SDR, so software-defined radio.
[19:08.980 --> 19:11.020]  So it's interesting how things get tagged.
[19:11.020 --> 19:19.340]  I find intriguing that there's not as much crossover as you'd think between all these terms, which I'll touch on a little bit later.
[19:19.340 --> 19:21.120]  So that's what this is.
[19:22.520 --> 19:25.020]  Moving on, there's a demo over there.
[19:25.160 --> 19:31.640]  If anyone's been to the NYC resistor table, they have this application running called GQRX.
[19:31.800 --> 19:40.140]  Again, if anyone's been into SDR for like more than a minute, chances are you come across this, especially if you're on the Linux side of the house versus Windows or Mac.
[19:40.980 --> 19:46.880]  It is able to work across multiple softwares, but this is kind of like the good universal way to start.
[19:47.080 --> 19:50.740]  Cool software, allows you to visualize, allows you to decode.
[19:51.020 --> 20:02.280]  The first capture flag on this is probably taking your $30 SDR, running GNU radio, and then tuning in some local FM broadcast and watching it on the screen and thinking it's the most amazing thing.
[20:02.540 --> 20:03.720]  But then you can do other things too.
[20:03.980 --> 20:08.800]  Receive amateur radio, police, Coast Guard, whatever.
[20:08.800 --> 20:10.500]  Also a lot of data signals.
[20:10.720 --> 20:12.120]  So there's a lot of cool things.
[20:12.280 --> 20:21.380]  And most importantly, it's a great way to learn about the dreaded dependencies when it comes to why things break when people upgrade different things in a project.
[20:21.560 --> 20:24.380]  So the nice thing with this is kind of like a good failover.
[20:24.540 --> 20:31.480]  If you're experimenting with like the leading edge software and something breaks, usually people fail over to GQRX just to make sure that you troubleshoot.
[20:31.580 --> 20:34.100]  Did you blow up your hardware or is it a computer issue?
[20:34.200 --> 20:35.760]  Some people have faulty USB ports.
[20:35.760 --> 20:38.160]  You know, this is like kind of a good way to test.
[20:38.200 --> 20:40.740]  Is it your SDR or is it your computer?
[20:40.920 --> 20:42.420]  Or is it something with your software?
[20:42.620 --> 20:43.600]  Is it doing what it's needing?
[20:43.760 --> 20:45.880]  And so this is interesting.
[20:46.000 --> 20:47.000]  This is of all of these.
[20:47.120 --> 20:49.540]  It's the only one that crosses over between the different terms.
[20:49.900 --> 20:56.240]  So both between SDR and software defined radio, this has what I'm calling double stars.
[20:56.740 --> 20:57.640]  I'm not surprised.
[20:57.820 --> 20:58.580]  It's also been around.
[20:58.580 --> 20:59.120]  It's the OG.
[20:59.120 --> 21:03.540]  It's the old gangster of SDR as I like to think about or we're pretty close to that.
[21:04.200 --> 21:08.560]  So again, if you're starting out or interested, I'm sure you probably have this already.
[21:08.840 --> 21:10.320]  So again, it's pretty cool.
[21:10.460 --> 21:13.100]  And like I said, toilets on the air.
[21:13.520 --> 21:16.600]  They're decoding some stuff that we're doing at the RF village table.
[21:17.920 --> 21:19.800]  And again, I'm not going to give you spoilers.
[21:19.820 --> 21:24.020]  Go and check that out over there in the... across the street.
[21:25.020 --> 21:26.040]  All right, moving on.
[21:26.280 --> 21:27.100]  So here we are.
[21:27.300 --> 21:28.300]  Fifth highest overall.
[21:28.540 --> 21:32.420]  This is the most highest velocity as it relates to ham radio.
[21:32.700 --> 21:36.680]  This is something called KV4PHT.
[21:36.920 --> 21:37.980]  That's his call sign.
[21:39.320 --> 21:40.600]  Show of hands quickly.
[21:40.840 --> 21:42.200]  Who's familiar with MeshTastic?
[21:43.740 --> 21:44.480]  Okay, good.
[21:44.740 --> 21:45.980]  This is not MeshTastic.
[21:45.980 --> 21:49.100]  I just want to make that... make that... make that point clear.
[21:49.580 --> 21:50.980]  But it's kind of a similar form factor.
[21:51.120 --> 21:59.180]  Basically what this is, it's like an SP32 device with like the low cost radio on a chip that you'd find in a Baofeng radio glued together.
[21:59.840 --> 22:09.160]  And basically you just take a USB-C cable, connect this to your smartphone, draws the power off of your phone, and it creates either a two meter or a 70 centimeter transceiver.
[22:09.900 --> 22:11.500]  You can communicate over voice.
[22:11.980 --> 22:14.200]  You can send and receive your GPS location.
[22:14.800 --> 22:16.400]  You can send little text messages.
[22:16.680 --> 22:17.560]  This is all off grid.
[22:18.020 --> 22:20.120]  So again, why say it's not MeshTastic.
[22:20.240 --> 22:21.040]  It doesn't use Mesh.
[22:21.140 --> 22:22.000]  It's not ISM.
[22:23.000 --> 22:24.040]  It's its own thing.
[22:24.220 --> 22:31.400]  But what's really cool about this is when this started about two years ago, this has grown really, really fast.
[22:31.600 --> 22:34.940]  And for like under 30 bucks, you can go and buy one of these.
[22:35.280 --> 22:37.800]  Now, yeah, you can also buy a full regular radio.
[22:37.800 --> 22:38.820]  But what fun is that?
[22:38.960 --> 22:40.420]  You know, this is something that you connect to your phone.
[22:40.800 --> 22:41.860]  And there's no air gap.
[22:41.980 --> 22:45.160]  You're not doing Bluetooth like MeshTastic to go Bluetooth to your device.
[22:45.600 --> 22:47.440]  So again, this is pretty cool.
[22:48.020 --> 22:56.460]  I was hoping to have this here in time for the presentation, but the old trick of I thought it was being shipped from New Jersey.
[22:56.720 --> 23:00.280]  Well, there was the shipping to New Jersey after it arrives from China.
[23:00.280 --> 23:02.660]  So it's somewhere in New Jersey now.
[23:02.860 --> 23:05.140]  I probably have it tomorrow, but that doesn't help us today.
[23:05.460 --> 23:07.520]  So anyway, it's still a pretty cool project.
[23:09.560 --> 23:11.580]  Highly expect people to look into this.
[23:12.180 --> 23:12.500]  All right.
[23:12.700 --> 23:13.680]  All in one cable.
[23:14.060 --> 23:16.380]  Make your $20 radio into a $200 radio.
[23:16.520 --> 23:17.920]  That is a tough feat.
[23:18.140 --> 23:20.520]  So whoever has like a basic Baofeng.
[23:20.660 --> 23:30.100]  Again, I just use that kind of as a generic term, but basically anything that has the speaker mic ports on the side, the two plugs, the 3.5 and 2.5 millimeter plug.
[23:30.440 --> 23:33.180]  This is both a combined hardware and software project.
[23:33.420 --> 23:36.640]  So basically what this is, is you plug this into the side of your radio.
[23:36.860 --> 23:42.800]  And that little circuit board has like a sound card and a keying circuit and converts it to USB-C.
[23:43.300 --> 23:50.160]  So what happens when you take a radio and you get this, you plug it in, take your USB-C cable, maybe you plug it into your smartphone or your computer.
[23:50.360 --> 23:51.600]  Now you have like full access.
[23:51.600 --> 23:56.900]  You can program the radio, you can send and receive messages and data and images and whatever.
[23:57.160 --> 24:00.180]  So that's what they call it, the all-in-one cable, because basically it does everything.
[24:00.400 --> 24:03.200]  In the past, you'd have to have like two different cables to do some of this.
[24:03.280 --> 24:09.000]  So it's a really cool way that you can take low-end radio equipment and do other cool things with it.
[24:10.300 --> 24:12.260]  Again, also TOTA related there.
[24:12.700 --> 24:13.380]  All right, moving on.
[24:13.800 --> 24:15.680]  Here we have something called SDR++.
[24:15.880 --> 24:26.440]  So probably once you get past the GQRX and you're looking for something like the next level, probably you come across something like SDR Sharp, which is older software, but it got a little too bloaty.
[24:26.940 --> 24:31.080]  And so Alex started work on this a couple of years ago called SDR++.
[24:32.540 --> 24:35.180]  It's similar in look to other software.
[24:35.540 --> 24:41.160]  So it has the same look and feel as like GQRX and SDR Sharp.
[24:41.400 --> 24:43.160]  It's very different than SDR Angel.
[24:44.100 --> 24:51.100]  What's unique about the way that he's dev this, and he's still a young fella, went back to school, took a little bit of a break.
[24:51.260 --> 24:54.360]  Anyone who follows him probably knows the whole history of this.
[24:54.600 --> 25:01.980]  But what's weird is when you go on Git and you look at it and you say, oh, well, maybe he's still busy doing school stuff.
[25:02.120 --> 25:03.840]  Looks like it hasn't been updated since 2022.
[25:03.940 --> 25:04.920]  That's not the case.
[25:04.920 --> 25:11.840]  It's because the way that he has this where a release automatically updates after each commit is pushed to the master branch.
[25:12.620 --> 25:15.700]  I'm so glad everyone's familiar with Git, so I don't have to explain that.
[25:15.840 --> 25:17.160]  But you all know what I'm talking about.
[25:17.320 --> 25:22.580]  But why that's important is when you go there, it's like his latest revision is like dated in June.
[25:22.760 --> 25:24.320]  So it's constantly evolving.
[25:24.320 --> 25:25.620]  So don't go off the fact.
[25:25.700 --> 25:33.460]  And again, when I look at stars and velocity and stuff like this, I could have almost made the fact to say, oh, disqualify that because it hasn't been updated since 22.
[25:34.380 --> 25:37.620]  If a project's not been updated for three years, it's probably not too popular.
[25:37.700 --> 25:38.400]  But that's not the case.
[25:38.540 --> 25:41.700]  It's just the way that he's decided to craft his Git.
[25:41.920 --> 25:43.260]  So this is a really cool software.
[25:43.860 --> 25:46.980]  There's a lot of special features that he's built into this.
[25:47.080 --> 25:50.360]  And there's other people that integrate this into other projects.
[25:50.420 --> 25:52.980]  And so I would highly encourage people to check this out.
[25:53.160 --> 25:55.820]  It is way more advanced than he makes it look.
[25:56.460 --> 25:58.220]  So really hats off there.
[25:59.660 --> 26:01.640]  And this is the last of the eight.
[26:01.860 --> 26:05.960]  And we only have like three and a quarter slides before I take some Q&A.
[26:06.100 --> 26:07.860]  So this is the best of the best of the best.
[26:07.940 --> 26:08.620]  You really need this.
[26:08.700 --> 26:10.980]  This is called Universal Radio Hacker.
[26:11.060 --> 26:14.660]  If anyone remembers that big green stripe that just looked like it was going to pop through the roof.
[26:15.460 --> 26:20.380]  This is a project that's been around for a really long time and it continues to gain a lot of traction.
[26:20.380 --> 26:29.820]  Basically, what this is, is a way that if you're looking at data signals, you want to figure out what that data signals actually comprised of.
[26:30.240 --> 26:32.140]  This allows you to figure that out.
[26:32.400 --> 26:46.280]  And let's say if you wanted to clone that signal, let's say if you have like a temperature sensor that you bought and you want to ingest it into some custom home energy management dashboard or something like I have.
[26:46.280 --> 26:53.740]  I use Universal Radio Hacker to figure out the way that that signal is structured and it allowed me to figure out how I can ingest that.
[26:53.960 --> 26:57.620]  You can also use it for another purpose, which is a bit of a gray area.
[26:58.040 --> 27:07.720]  So let's say if you had like a garage door opener and you wanted to clone that signal and use an SDR to transmit your garage door signal as like a replay.
[27:07.920 --> 27:09.840]  You can use Universal Radio Hacker for that.
[27:09.940 --> 27:14.500]  And again, I'm just touching on the surface, but that's not just me being a fan of this.
[27:14.500 --> 27:18.280]  This is another like 11,000 people that have already said that this is really cool.
[27:18.820 --> 27:22.700]  So Universal Radio Hacker, like I said, something you really need this.
[27:23.360 --> 27:26.400]  Another project out here, just for a quick shout out, RTL 433.
[27:26.920 --> 27:33.260]  If anyone's tried to decode like tire pressure monitor sensors and weather things and whatever.
[27:34.040 --> 27:35.480]  It's kind of a fun thing.
[27:35.680 --> 27:38.120]  It's third most stars, six highest velocity overall.
[27:38.380 --> 27:40.440]  The two of them kind of go hand in hand, sort of.
[27:41.020 --> 27:44.360]  But again, URH, Universal Radio Hacker, super cool.
[27:45.120 --> 27:47.540]  Finding all sorts of things in all sorts of spectrum.
[27:48.500 --> 27:48.820]  All right.
[27:49.020 --> 27:56.500]  So as we start to close things up, I'm sure some of you out there are like, man, how come there are some other common ones that haven't been talked about?
[27:56.840 --> 28:00.380]  And that's where we come to our friend HackRF.
[28:01.640 --> 28:06.520]  Then we're going to talk about something related to that called Mayhem or Portapack.
[28:06.720 --> 28:09.100]  Depends on who you ask, but I'll clarify that in a second.
[28:09.540 --> 28:12.380]  Then we have the last one on here called Open Wi-Fi.
[28:12.620 --> 28:13.000]  So that's cool.
[28:13.140 --> 28:18.660]  But again, the takeaway from this chart, number one through ten, highest velocities.
[28:18.880 --> 28:19.840]  And then where do they rank?
[28:20.040 --> 28:23.340]  So again, like I said earlier, SDR as an abbreviation.
[28:23.340 --> 28:30.160]  Almost everything that is thought to be the coolest things based off of stars, it's clear right here.
[28:30.760 --> 28:32.700]  All but two are in that category.
[28:33.080 --> 28:48.560]  One from Software Defined Radio, which is a make your own cellular base station type of project at the bottom called SRS RAN 4G, which I'm not going to cover because I'm not getting in trouble with like Verizon and T-Mobile by saying how to make cell phone mini base stations.
[28:48.560 --> 28:49.260]  But you can do that.
[28:49.460 --> 28:49.740]  That's cool.
[28:50.260 --> 28:52.620]  And then we already talked about KV4P.
[28:53.280 --> 28:54.980]  So, all right, here we are.
[28:55.180 --> 28:56.800]  HackRF, super big news.
[28:56.940 --> 28:58.100]  This I'm super excited about.
[28:58.300 --> 29:04.280]  So since 2014, when they came out with the original, Michael Osmond came out with their original HackRF, it changed the game.
[29:04.480 --> 29:15.100]  I think it's hysterical that when you go to Git and people put descriptions on projects, this is the official description of HackRF, low cost software radio platform.
[29:15.500 --> 29:16.100]  Less is more.
[29:16.100 --> 29:17.500]  That's all he has.
[29:17.780 --> 29:21.320]  I had to actually come up with more words just figuring that somebody might want to see this.
[29:21.420 --> 29:23.680]  So this is the official project description, 2014.
[29:24.040 --> 29:24.820]  This was true.
[29:24.940 --> 29:27.720]  And 10 years later, it's still pretty based off of what the HackRF can do.
[29:27.980 --> 29:32.500]  However, now here we are in 2025, that hardware has been getting long in the tooth.
[29:32.780 --> 29:35.580]  And so now he has an updated version called the HackRF Pro.
[29:35.840 --> 29:38.560]  It's targeted for official release in like October.
[29:38.860 --> 29:41.340]  There's some pre-samples floating around out there.
[29:41.340 --> 29:44.600]  But basically, this offers wider frequency coverage.
[29:44.800 --> 29:48.840]  So it goes up to like six gigahertz instead of, I think, like three and a half gigahertz.
[29:49.020 --> 29:55.020]  It has a USB-C interface because we're probably starting to not know where our stash of USB micro cords is hidden.
[29:55.680 --> 29:57.660]  And overall, it's basically the same thing.
[29:57.760 --> 29:59.180]  There's a lot of other things that have changed.
[29:59.180 --> 30:02.220]  But for the most part, those are like the two biggest like ahas.
[30:02.380 --> 30:04.980]  More spectrum and faster interface.
[30:05.640 --> 30:07.320]  And again, this is a piece of hardware.
[30:07.540 --> 30:09.460]  You need to connect it to a compute device.
[30:09.780 --> 30:13.380]  And you need to run software like the GNU logo is that orange one.
[30:14.380 --> 30:18.820]  One of my favorite ones, which I couldn't talk about because again, I didn't want to show bias here.
[30:18.900 --> 30:24.020]  Something called SDR Angel, even though it's in the list, but not in the way that I've structured this.
[30:24.020 --> 30:26.040]  So there's lots of cool software that you would use.
[30:26.160 --> 30:35.520]  I have a HackRF at the RF Village, which is transmitting nine simultaneous signals on different frequencies at the same time.
[30:35.600 --> 30:39.140]  So if anyone wants to figure how I'm doing that, come on by.
[30:39.140 --> 30:41.040]  I'm doing that with SDR Angel.
[30:41.720 --> 30:46.220]  And then we get to something called Portapack or the Mayhem firmware.
[30:46.720 --> 30:57.260]  So basically if anyone remembers like an iPod or a Zune, that's like an obscurity from like Microsoft before iPod, Apple iPod took over the world.
[30:57.500 --> 30:58.760]  Basically, this is like a hat.
[30:58.860 --> 31:03.980]  You attach this to the RF deck and it has a screen and a jog wheel and the processing power.
[31:04.100 --> 31:09.640]  And basically you can do a lot of cool RF things right in the palm of your hand has built in battery and everything.
[31:09.640 --> 31:22.060]  So if you want to like monitor spectrum or do replay attacks or, you know, mess with like your neighbors, Tesla and open its, you know, gas door or whatever, there's like all sorts of cool things, you know.
[31:22.680 --> 31:24.400]  So you can buy these online.
[31:24.820 --> 31:27.140]  The cost has come down since the original Portapack.
[31:28.060 --> 31:29.840]  So this is what it looks like.
[31:30.380 --> 31:35.980]  But I think the big takeaway on this is expect the increase in stars as the HackRF Pro is released.
[31:35.980 --> 31:41.000]  So even though it's held its own over the years, I think now we're coming to like the next generation.
[31:41.000 --> 31:42.780]  So there's going to be a lot of extra development.
[31:42.940 --> 31:55.940]  I really think that everything beyond HackRF that Michael Osmond has done for Swap Dr. Define Radio, he's like one of the original guys that's like hacked the drivers and figured out how to take these TV tuners and create like what we know is like hobbyist SDR devices.
[31:56.980 --> 31:58.880]  I think this is going to really blow up.
[31:59.000 --> 32:00.460]  It's going to gain velocity.
[32:00.460 --> 32:02.920]  So I'll keep that page active.
[32:03.160 --> 32:10.580]  And I think much like we saw with Universal Radio Hacker, I think you're going to see this really start to take off even more as that comes out.
[32:10.760 --> 32:12.900]  And again, this is like both hardware and software.
[32:13.120 --> 32:17.160]  So the Mayhem firmware really added a lot that the original Portapack did not do.
[32:17.880 --> 32:23.000]  And again, very TOTA related because I'm broadcasting TOTA related contact stuff over at RF Village.
[32:23.000 --> 32:27.980]  And the last one, this is kind of like very different than like everything.
[32:28.200 --> 32:35.700]  And again, when you kind of dig into data on things, you kind of start to discover like these neat little trends like the key V4P.
[32:36.120 --> 32:37.320]  Here's open Wi-Fi.
[32:37.520 --> 32:39.040]  This is the fourth highest velocity.
[32:39.200 --> 32:41.600]  And that's out of the 40 things that I've reviewed.
[32:41.940 --> 32:42.780]  Well, 10 of them today.
[32:44.000 --> 32:52.700]  But basically, this is using software to find radio hardware and creating your own Wi-Fi type devices.
[32:52.700 --> 32:57.720]  Now you think, well, Steve, you can buy a Wi-Fi chipset dev board for like nine bucks.
[32:58.120 --> 33:01.120]  Why do you need to spend like $180 on HackRF?
[33:01.720 --> 33:02.500]  Well, because you do.
[33:02.840 --> 33:04.280]  So that's what you do it, right?
[33:05.160 --> 33:08.960]  But joking aside, there's other things, especially those into amateur radio.
[33:09.120 --> 33:16.120]  Now, when we think of Wi-Fi, we often think about like 2.4 gigahertz or 5.8, or now we have 5.9 and 6.0 gigahertz.
[33:16.720 --> 33:23.900]  But let's say if you're an amateur radio person, you want to do Wi-Fi, like as like an 802.11 based standard over 900 megahertz.
[33:24.300 --> 33:26.100]  Here's your development platform for that.
[33:26.200 --> 33:31.780]  And there's other devices that address that 900 megahertz gap, which is its own topic for a different day.
[33:32.180 --> 33:34.260]  But I think that this is really cool.
[33:34.500 --> 33:38.740]  And since I mentioned it before, the RAND 4G project.
[33:38.940 --> 33:51.580]  Now, let's say if you wanted to make like your own cellular base station and your own like software emulated Wi-Fi, if anyone's like an aspiring network dev or you want to do cool stuff, this is like, like leading edge.
[33:51.780 --> 33:54.520]  And again, the fact that overall, this kind of sneaks in there.
[33:54.660 --> 33:58.540]  This is technically hidden under SDR.
[33:59.060 --> 34:01.060]  And again, like I said, it's the fourth highest velocity.
[34:01.180 --> 34:04.860]  So this is something that's come on fairly quick and gained a lot of popularity.
[34:04.860 --> 34:08.840]  Not the total stars, but again, how fast is it gaining a popularity?
[34:09.040 --> 34:10.660]  So something definitely to take a look at.
[34:11.820 --> 34:16.420]  And as we kind of wrap things up here, like I said, Git search matters.
[34:17.120 --> 34:20.440]  Don't just apply this like, you know, SDR compared to software defined radio.
[34:20.680 --> 34:31.360]  If you're doing a search for like application security versus AppSec or operational security or OpSec, do different variations because you're going to pick up different things.
[34:31.520 --> 34:32.980]  It doesn't have a relative search.
[34:32.980 --> 34:35.420]  So if you're looking for something, get creative.
[34:35.560 --> 34:36.860]  You might find some other things.
[34:37.960 --> 34:41.420]  Also, just because a project's been around for a long time doesn't mean it's the best.
[34:41.660 --> 34:49.740]  This is kind of an issue within the amateur radio repositories where there's things that have been out there for like forever, but like they've pretty much stayed flat.
[34:49.940 --> 34:53.740]  Like nobody's really cared, even though they're like, they're underpinnings of a lot of other things.
[34:54.120 --> 35:01.380]  So again, showing just because a project's been around for a long time doesn't mean it's the best, but also just because it's the newest doesn't mean that it's the best.
[35:01.380 --> 35:03.880]  So that's probably making your brains hurt a little bit.
[35:04.600 --> 35:11.920]  But again, just because it's newest, maybe they need to develop it kind of like with CloudLog got forked into WaveLog.
[35:12.020 --> 35:18.160]  If we look at like HackRF and Portapack and Mayhem, again, people learn, people fork, things always get better.
[35:18.300 --> 35:20.500]  But like keeping an eye on things, it's always exciting.
[35:20.500 --> 35:27.980]  Like when you find something early, and it becomes to be like a really popular thing, kind of makes everyone feel good that they were like an early adopter.
[35:28.180 --> 35:30.580]  And like I said earlier, go meet people here.
[35:30.580 --> 35:35.040]  You know, we all have unique talents and skills and knowledge and stuff.
[35:35.280 --> 35:36.120]  Don't be afraid.
[35:36.380 --> 35:42.520]  Some of us are afraid to interact with people, but we all have goofy hats and other trinkets with us to strike up a conversation.
[35:42.740 --> 35:45.000]  So hopefully everyone gets to meet some new friends here.
[35:45.280 --> 35:49.500]  And because I have to say it, you know, get your ham radio license because you need it.
[35:49.700 --> 35:51.140]  So that is it.
[35:51.820 --> 35:52.580]  Thank you.
[35:52.800 --> 35:54.100]  And questions?
[35:55.100 --> 35:56.720]  We're good on time for questions?
[35:56.720 --> 35:57.540]  We're so good on time.
[35:57.560 --> 35:57.820]  All right.
[35:57.880 --> 35:58.200]  I thought so.
[36:05.330 --> 36:07.030]  I'm going to ask the first question.
[36:08.390 --> 36:09.030]  Hey, everyone.
[36:09.110 --> 36:10.190]  I'm going to ask the first question.
[36:10.650 --> 36:11.810]  I haven't had lunch.
[36:12.190 --> 36:21.390]  So a question that I have is, it might be slightly adjacent to everything that you've been talking about, but I've got this RTL-SDR and it's the V4 version of it.
[36:21.510 --> 36:27.430]  And I know that there are, the drivers are slightly different from like the Osmocom ones.
[36:28.430 --> 36:34.590]  What is your understanding of like which tools are compatible with this new driver and hardware?
[36:35.150 --> 36:35.710]  All right.
[36:35.850 --> 36:36.630]  So that's a good question.
[36:36.790 --> 36:39.630]  And I'm glad it's a question that I could actually answer in pretty good depth.
[36:39.790 --> 36:45.710]  So for what Moon asks, RTL-SDR or RTL-SDR.com.
[36:45.930 --> 36:51.790]  So like in the early days of like when people started to find these little TV tuner dongles, they want to find something.
[36:51.790 --> 36:56.650]  Well, you got to have drivers for it to convert it to do things that we want them to do.
[36:57.350 --> 37:00.130]  So there was RTL-SDR version three.
[37:00.730 --> 37:02.350]  It's been around for a long time.
[37:02.670 --> 37:05.210]  The chipsets actually getting a little harder to source.
[37:05.410 --> 37:07.170]  And so they found a different one.
[37:07.250 --> 37:12.790]  It's actually a better quality chipset, which is what rolls into what's called RTL-SDR version four.
[37:12.790 --> 37:20.470]  The difference is, and again, like you could search for RTL-SDR.com and there's like a wiki that kind of covers some of this.
[37:21.370 --> 37:25.550]  Some of the benefits of the V4 hardware is that it runs lower temperature.
[37:25.550 --> 37:29.710]  If anyone has an SDR, they know that it runs pretty hot after a while.
[37:30.170 --> 37:31.550]  The V4 runs a bit cooler.
[37:31.710 --> 37:36.410]  It also has better what's called signal to noise ratio in certain areas of spectrum.
[37:36.410 --> 37:39.750]  The exciting thing is it's like areas that actually are fun to explore.
[37:39.970 --> 37:49.550]  Like what I call ISM spectrum is license free, where you're probably going to be doing most of your, you know, exploring anyway around 433 and 900 megahertz.
[37:49.950 --> 37:54.590]  So it actually has like a little bit better oomph is the way that I call it.
[37:54.710 --> 37:55.550]  So the hardware is better.
[37:55.670 --> 37:59.530]  Now the problem is, as Moon asks, it needs a different driver.
[37:59.870 --> 38:03.230]  When it first came out, it was hard to get this thing to work.
[38:03.230 --> 38:05.510]  And I was part of like an early dev on it.
[38:06.450 --> 38:09.910]  Today, a lot of it's all went downstream.
[38:10.230 --> 38:12.930]  So it's integrated for things easier.
[38:13.170 --> 38:21.410]  But if you do run into issues with like a driver, if you plug, if you buy a V4 within the differences, the V3s are silver and the V4s are black.
[38:22.590 --> 38:35.390]  If you buy a V4 and you plug it in and you go to GQRX as an example, and it says no worky, you go to the RTL SDR website, and they have their own Git repository, you can download updated drivers from there.
[38:35.390 --> 38:39.570]  But they also have that integrated into the Osmocom ones now.
[38:39.750 --> 38:40.830]  So it's all downstream.
[38:41.210 --> 38:46.230]  And so if you haven't tried it in a while, Moon, try it again, and it should probably work pretty easy.
[38:46.390 --> 38:46.630]  Cool.
[38:46.930 --> 38:47.090]  Thank you.
[38:47.210 --> 38:47.690]  Good question.
[38:47.910 --> 38:49.510]  And that was not seeded, I swear.
[38:49.930 --> 38:50.810]  Not seeded.
[38:50.890 --> 38:52.410]  We just met each other like a few minutes ago.
[38:56.610 --> 38:57.390]  Question in the back?
[38:58.750 --> 39:00.210]  I had a question about the Flipper Zero.
[39:01.570 --> 39:02.510]  I'm kind of curious.
[39:02.850 --> 39:03.730]  I think it's open-source.
[39:03.910 --> 39:06.710]  I'm kind of curious if you have any thoughts about why it wasn't popular.
[39:07.170 --> 39:09.630]  But also, do you know how that compares to the Mayhem?
[39:09.750 --> 39:11.430]  Is that kind of like the same type of thing?
[39:11.690 --> 39:12.810]  Or is that I totally understand?
[39:13.230 --> 39:14.150]  No, you need both.
[39:15.650 --> 39:22.090]  So the question for those that didn't hear it is asking about the Flipper Zero, which is a really cool device.
[39:22.930 --> 39:24.670]  Question is, why was that not covered?
[39:24.850 --> 39:25.550]  I'll get to that.
[39:25.750 --> 39:29.950]  And then how does it compare to like a Portapak or a Mayhem?
[39:31.490 --> 39:33.750]  So one, why it was not covered?
[39:34.090 --> 39:37.470]  Because again, I went like full on democratic mode.
[39:38.230 --> 39:40.050]  It's not tagged.
[39:40.310 --> 39:45.670]  And I think this is what's interesting is like the Flipper Zero is kind of a weird little side area.
[39:45.670 --> 39:47.590]  It's not really SDR.
[39:48.510 --> 39:49.790]  Certainly not ham radio.
[39:49.930 --> 39:51.150]  Can it be used for both things?
[39:51.310 --> 39:51.570]  Probably.
[39:51.870 --> 39:57.810]  But on git, whatever the key tag words are, that's why it didn't come up.
[39:58.390 --> 40:06.670]  I think if we expanded it like to see like what are the tags for Flipper, like probably CC1101 is one of the ISM chips that are in there.
[40:06.810 --> 40:13.130]  I bet if we did a search for CC1101, I bet it's probably going to be in there and it's probably going to be super high.
[40:13.830 --> 40:16.970]  But they do totally different things.
[40:18.470 --> 40:23.430]  That's a presentation for the two of us to collab on next year, I think.
[40:25.990 --> 40:28.650]  But it's a unique device with unique capabilities.
[40:28.950 --> 40:32.070]  I think both do different things different.
[40:33.910 --> 40:37.350]  There's also another type of device that's like a Flipper.
[40:37.530 --> 40:40.490]  There's a few of them like on CrowdSupply and a couple of the other...
[40:40.490 --> 40:43.430]  You know, my Kickstarter has like a few other ones that are kind of similar.
[40:44.330 --> 40:47.270]  It's a hard question to ask, but that's why it didn't trigger.
[40:47.850 --> 40:48.950]  And they're very different.
[40:49.690 --> 40:52.470]  I would highly encourage you to just buy both.
[40:52.670 --> 40:53.550]  You'll be very happy.
[40:53.710 --> 40:55.810]  And I do not get any kickbacks from these companies.
[41:00.090 --> 41:01.490]  Yes, in the back.
[41:02.410 --> 41:03.030]  Yes, Steve.
[41:03.310 --> 41:08.170]  Also to your point about the version 3, version 4 for RKL, you're right, it did get downstream.
[41:08.170 --> 41:13.270]  I know on the Ubuntu repo, at least for 24.04, it's all updated.
[41:14.470 --> 41:17.530]  We discovered that when we were doing the update to the SIGFI.
[41:19.570 --> 41:21.370]  So Joe and I actually know each other.
[41:22.650 --> 41:25.910]  So that was more like a validating thing, but was there a question in there, Joe?
[41:27.170 --> 41:28.710]  I'm just validating what you're saying.
[41:28.710 --> 41:29.370]  Okay, all right.
[41:29.530 --> 41:32.270]  Yeah, so basically for those that didn't hear what Joe said was...
[41:33.010 --> 41:45.110]  Joe and I worked together on quite a few projects, but one of them, which was kind of fun timing, was we worked on a project called SIGFI, which as its name sounds, involves signals and Raspberry Pi.
[41:45.110 --> 41:51.510]  And it was kind of fun timing because many of these projects, like SDR Angel, continue to update.
[41:51.770 --> 42:00.950]  And then hardware was updating, and it was really starting to irritate us, because sort of going back to Moon's question was, where are the drivers?
[42:01.150 --> 42:07.970]  And one of the things that we struggled with was, as we were building in other applications into our project, things weren't working.
[42:07.970 --> 42:13.570]  And it was really kind of a daunting task to get the V4 to get supported.
[42:14.290 --> 42:20.410]  And then literally, if we just said, you know what, let's just take a vacation from this and come back in three weeks, that's basically all it took.
[42:20.550 --> 42:22.010]  We just had to wait for it to just trickle down.
[42:22.270 --> 42:26.770]  So again, if anyone had a V4 and got annoyed, go back.
[42:26.930 --> 42:29.730]  It's pretty much supported in like any mainstream app now.
[42:29.890 --> 42:30.870]  But thank you for that, Joe.
[42:35.490 --> 42:36.210]  Any others?
[42:37.550 --> 42:37.950]  Yes.
[42:38.410 --> 42:41.490]  Would it be just possible at the end to flip back from the QR code?
[42:41.630 --> 42:43.510]  I couldn't quite get it from here, so sorry.
[42:44.170 --> 42:45.850]  Do you want the big one or the small one?
[42:45.950 --> 42:46.850]  I guess it's possible.
[42:47.390 --> 42:47.770]  All right.
[42:47.850 --> 42:48.330]  Tiny one.
[42:49.590 --> 42:49.970]  All right.
[42:50.050 --> 42:51.350]  Let's see if you can get it from that angle.
[42:52.490 --> 42:53.790]  I guess I'll speak it.
[42:53.910 --> 42:58.630]  It's hvdn.org backslash hope16.
[42:59.050 --> 43:00.730]  I think that's the URL that I made.
[43:01.150 --> 43:01.650]  Good to go.
[43:01.790 --> 43:02.110]  Thank you.
[43:02.250 --> 43:02.430]  Yeah.
[43:02.630 --> 43:03.250]  You got it.
[43:05.490 --> 43:06.010]  All right.
[43:06.010 --> 43:07.870]  I see people are moving on to the next.
[43:08.230 --> 43:10.070]  So any other questions or?
[43:11.830 --> 43:12.490]  We're good.
[43:13.910 --> 43:14.470]  We're good.
[43:14.650 --> 43:16.630]  I got an official thumbs up from the gentleman in the front.
[43:16.830 --> 43:17.470]  Double thumbs up.
[43:17.610 --> 43:18.190]  Triple thumbs up.
[43:18.310 --> 43:18.550]  Thank you.
