[Elecraft] [K3] Strange S meter behaviour

[ab2tc]

Hi,

Is the K3 with the crazy S-meter really old and without the HAGC
modification? If so, doing the HAGC modification will improve this but in my
case did not fix it entirely. Anyway, you should be able to correct the
situation by doing the RX gain calibration with the optional S9+40dB step.
The bad news is that your XG2 is will not provide this signal. The XG3
however, will.

PS. At 0F temperature this morning my remote KAT500 was still doing fine
with no perceptible change in tuning.
