Hi,

I am fully aware that slow AGC has its limitations in the presence of static
crashes, although the K3 does a fairly good job of not "hanging" on those.
All I and others are asking is that the receiver not remember the signal
strength prior to transmitting, but rather reset it to a no-signal condition
when resuming receive. This is not asking the impossible.
