[Elecraft] K3 - Can't hear 40m sigs in sub rx

[Don Wilhelm]

John,

The most common cause of that problem is the SubRX antenna selection - 
that is a per band setting.

Go to 40 meters and get into BSET - then tap the RX ANT button.

If that does not restore proper operation, contact Elecraft support.

If I turn up the Sub RX gain a LOT, I hear a little noise, but I think it’s just receiver noise. The problem is only on 40 meters, in all modes. All other bands are working just fine.
