BULLETIN # 910
MODEL: TS-940S
SUBJECT: AGC CIRCUIT IMPROVEMENTS 

The following changes will improve the adjacent channel rejection of 
the TS-940S when a relatively strong nearby signal is present (S-4 or above).
The AGC switch should remain in the SLOW position for all but high speed 
data communications. Most CW operations will also benefit from operation 
in the SLOW position.

Parts Required:

	15K ohm 1/4 watt resistor	    RD14CB2E153J
	1 uF 16v Electrolytic	            CE04BWlE010M
	lS1555 diode            	    V1S1555
	.047 uF capacitor	            C91-0119-05

Procedure:

RF UNIT

1. Remove jumper wire JP7 and replace it with the parallel combination 
   of the 15 k ohm resistor and the 1S1555 diode. Pay close attention 
   to polarity. The cathode goes TWORD Q15.

2. Add the 1 uF capacitor from the added resistor/diode junction (cathode
   end) to ground.

IF UNIT

Change capacitor C75 from a 1 uF 50 v capacitor to a .047 uF 50v capacitor.
