K3: AGC misbehaving

[Ralph Parker]

While listening casually to the NA contest today, I noticed that the AGC
was behaving thusly:

In CW mode, the ACG is set to 'SLOW' (I prefer it that way). Firmware 2.72.
When receiving a relatively strong signal, the AGC seemed to be in 'FAST'
mode for the first 1-2 seconds, then in 'SLOW' mode for the rest of the
transmission. This would repeat for every received transmission.
I was not transmitting at any time.
Am I overlooking an AGC CONFIG setting?

Hi Ralph and Elecrafters

I believe I am experiencing the same issue as you as regards slow AGC. What
happens with a strong CW station is that the s meter peaks then falls away
rapidly for the first few characters before settling down. Is this what you
are experiencing Ralph ?

You may want to try setting AGC PLS=OFF. I notice the same thing when
this setting is on. With this setting on, It appears to me that the AGC
pulse rejection will cause the AGC to react too quickly on some CW
elements .
