[Elecraft] K2 RF Gain control

[Robert Greenwalt]

I have a K2 with almost all of the add-ons (everything but DSP - and the
100 watt amplifier has just been added) and all elecraft mods that has
functioned well for over a year - but I recently noticed that the RF
gain control doesn't change signal levels coming out of the speaker.
The control has been left at max until I played with it recently, and I
was surprised to notice that its only function seems to be changing the
number of illuminated LEDs in the S-meter.  I tried it with various AF
gain control levels and with the AGC both active and turned off - no
difference.  Before I get into massive troubleshooting, is it possible
over time and changing various internal settings several times I have
misadjusted something?  I get signals on the bands.
