Thanks Don. Yes, I had a senior moment on the resistor va
A couple of people have posed a question to me off the reflector that speaks
to a point I think is important: when checking to see if the volume changes
when switching the AGC on and off, do it with *no antenna*! Best, a 50 ohm
dummy load connected!

Roy,
You must have misread something (or did a typo). The stock value for
Control Board R1 on the older boards is 51k. A 50k pot will do the task
for you, or a 20k pot in series with a 33k resistor. I typically find that
a 39k, 36k or 33k resistor will set the proper level, but I have also fou
After reading Don's (W3FPR) AGC procedure, curiosity got the best of me. I set
up my parameters as he stated and was surprised to find a considerable
difference between AGC ON and AGC OFF with AGC OFF being considerably louder.
I am going to remove R1 (71K) from the Control Board and substitut
Paul,
You are correct, there is no well defined procedure, and part of the real
procedure depends on 1)whether you set the pre-amp on or off, 2) the band
that you use to optimize the AGC, and 3) the sensation in your ears as you
listen to the result - An AGC Threshold setting that is higher than

Hello All:
What is the proper way to set AGC in the K2?
The manual suggests adjusting R1 for 3.80V at U2-5 as a starting point, but
then gives no other information.
