K3: AF Gain delay?

[Joel R. Hallas]

Folks,

I notice a significant delay in response to the AF Gain control while in
receive so far just one receiver here!). I'm not sure if it has always been
this way and I hadn't observed it b4, but certainly for the last few F/W
upgrades. I haven't done the most recent beta version since my radio PC is
currently "casters up."

It doesn't matter the mode, BW, AGC or NR setting. With a loud signal
present, turning the AG Gain down seems to have no effect until it is down
way too far, likewise when bringing it back up to compensate. I finally
decided it was working, just exhibiting a delay of somewhere around 1/4 -
1/2 second.

Have others noted this and/or, better yet, found a way to avoid it?

Thanks much!

Regards, Joel

I had the same problem several weeks ago.  Check the AF knob and see if it's
cracked and slipping on the shaft.  My unit was a factory built unit.

Mine [#642, home built, 2.13 FW] doesn't exhibit any delay that I can tell.
