The Interceptor® measures deviation (wide and narrow band), relative signal strength, and signaling tones (CTCSS, DCS, and DTMF) using the companion DC440 Decoder. The R10 can be used for any measurement requiring demodulated FM. The R10 is ideal for testing VHF, UHF and Cellular transmitters and can be a low cost, highly portable substitute for a service monitor in some applications.

New Technology

The Interceptor® responds to any strong signal present, unlike a conventional radio receiver or scanner. Conventional receivers are stabilized and tuned to a particular frequency by an internal oscillator. The Interceptor® is stabilized by the signal it is receiving. The advantage of this process is that the Interceptor® does not have to be tuned to a frequency in order to receive a signal. Any FM signal from 30MHz to over 2GHz can be intercepted without gaps in coverage. The Interceptor is completely automatic for hands free operation.

Security & Counter Surveillance Applications

The Interceptor's® great sensitivity to Near Field signals makes it ideal for RF security and counter surveillance applications. The signal strength bargraph is useful in locating stuck transmitters or listening devices concealed in a room or automobile.

Communications Monitoring in the Near Field

Unlike scanners and receivers that must be tuned to a specific frequency or scanned through a fixed frequency range, the Interceptor® will provide an exciting new dimension to recreational monitoring with near instant response to strong signals. Communications monitoring hobbyists will be able to take the Interceptor® on cruise ships, to military bases, theme and amusement parks, zoos, airports, to space shuttle launches, parades, sporting events, car races, and anywhere else two-way FM communication is used.

• Pocket Sized
• For test applications, demodulated audio output is available from a stereo phone jack
• Built in speaker
• An earphone is supplied and optional personal stereo headphones are available for discrete monitoring
• Thumb wheel volume control/power switch is mounted on the top of the instrument
• Audio output is maintained down to 50Hz for tone measurements with a counter or decoder
• A thumb wheel squelch control is mounted in parallel with the volume adjust pot
• Skip push-button frees the Interceptor® to lock on to a different signal. This function is very useful when several relatively strong signals are present. Most Near Field instruments can only lock onto one strong signal while the Interceptor® is able to be released to intercept additional signals
• Dual 10 segment bargraphs provide deviation and relative signal level indication
• A push-button switch selects wide band or narrow band bargraph calibration
• High intensity LED bargraph
• Lock indicator to indicate signal interception
• The interceptor is supplied with a telescoping whip antenna with a BNC connector, and internal NiCad battery pack for up to 6 hours of operation before recharge becomes necessary and an AC wall plug charger is supplied that will also permit operation from the AC power line
• Low battery indicator

Antennas - Maximize performance for a particular band.
Filters      - Eliminate unwanted signals outside the desired band.
