QCX AGC Module: Value of R204

R204 is a zero ohm (short circuit) installed only if you want the AGC to stay on all the time. Leave it open circuit if you want to control the AGC on/off via the firmware ... 73 ... Ron

QCX AGC Module: Value of R204

Hello, the AGC Module is out of stock and so I would build it on the expansion board or on small stripboard. But I don't know what's the value of resistor R204 for the switching circuit? Can somebody

Ivan, as a start, I think you should use your DVM and make sure all is well with the installation. So. with the unit OFF, use the ohm meter and look for continuity from pin 1 of IC10 to the "AF Out" p

I have experienced similar situations. The issue comes with trying to break the 'short' by 'nudging'. I find the best solution is to use a solder sucker to remove the solder from the through hole devi
