[Elecraft] not receiving PSK or any SSB audio

[Julie Royster]

I had written about my husband's new problem of no longer receiving PSK
signals, and we had thought it was the FLdigi setup.
This morning I removed the computer hookups, removed the KXPA100 via the
menu following Matt's suggestion, got the latest firmware, and tried to
receive SSB, but nothing is heard.  So evidently we are not receiving
amateur radio signals of any kind at present.  With the audio all the way up
I can barely detect a commercial radio station.  Does anyone have any clues
what might be going on?
Cheers and 73,
