[Elecraft] K3 Sub RX stopped working on 20/17 meters

Reload your saved firmware?  I have run into issue solved by reloading firmware.  It is like your PC doesn't work so well when a restart dumps all the memory and reloads the OS.

Hi Folks,

Just learning my way around the KRX3A.  For reasons I can't determine, it stopped working on 20 and 17 meters.  Works fine on the other bands.  I have tried with both main and AUX antennas.  I know it worked when first installed.  B_SET settings all seem normal, mode, bw, atten, etc.  I can't get it work work again. It has static when the AF Gain(SUB) is advanced, but no indication on the S-Meter when B_SET selected on an S-9 signal and no signal in the headphones on the Sub side.  Have I somehow got it confused and it's trying to use a different band's lo pass?  I have not experimented with "cross-band" sub rx operation.  Maybe I inadvertently switched bands with SUB enabled and got it mixed up???  Dunno.

The manual is open on my desk.  Can't find anything that might be wrong.
Firmware is all up to date.

Any ideas?

Chris
