[Elecraft] Update: K3 Hard of Hearing

[John Unger]

Wow, guys, thank you all for the suggestions of things to check, but still
no joy...

Here's your suggestions that I have checked:
voltage - 13.6
RX ANT not on
I uploaded a couple of old config files - not change
Turning RF GAIN fully CCW puts SWR meter at full scale
My other K3 hears FB on all the antennas
This K3 doesn't have an ATU
Switching an antenna in and out makes no apparent difference in received
signals
No change in BP filters; they have been working fine for long time.

I do operate SO2R. The last time radio was working OK was during the NAQP
CW contest where I was running 100W. I have operated KW amps in the past on
each radio without any front end problems (but there's always the first
time, right?).

Thanks again for the help
