K3 Loss of receive audio on SSB

Lee Trout
*I have experienced this problem four times now and I see from the archives
that others have experienced it too.  For no apparent reason there is a
total loss of receive audio in the SSB mode.

If the width is opened to above 3 kHz, receive audio returns to normal;
decrease the width below 3 kHz and the audio mutes again.

I have reset the filter offset, no help.  Although no changes have been made
in filters, have double checked all settings both in the radio and via the
K3 utility.  If, in the CONFIG menu, with FL1 ON showing in the LSB mode, I
cycle the mode switch to FL1 ON in CW, then back to FL1 ON LSB, the receive
audio comes back on.  But, after exiting the CONFIG menu, the audio mutes
again.

The only thing that restores the radio to normal operation is to do a
Restore Configuration from the K3 utility.  One time did a total radio reset
combined with a Restore Configuration. This problem has just cropped up
within the last month or so.  K3 is #1737, running version 4.25.  Filters:
2.7; 400.

This problem seems rare -- have seen only two other postings on it.

Any ideas?  Thanks, Lee (K9CM)*

Hi Lee,

So far I haven't been able to reproduce this. Please send me as much  
detail as possible on what you were doing (and how the radio was  
configured) just before it happened. Also include your firmware  
revision. If you try an older revision that does not exhibit this  
behavior, let me know.

Tnx
