[Elecraft] K3 no SSB receive

[Hank P]

On any band   CW/DATA/AM receive normal  both main and sub dead on SSB 
either sideband. Can watch the P3 and signals obviously still coming out of 
the IF but rx goes dead when MODE is tapped to USB . And I mean DEAD - not a 
whisper phones or speaker RF and AF gain wide open. NB/NR on or off no 
change.

Saw that W4BQF has same issue - but could not find any responses.
