Audio Nulling in my K3 in Diversity

Hi All,

For the last few weeks I have used the Diversity on the low bands with good
success.  

Tonight I came into the shack and found my K3 acting strange.  While in
diversity, 4SQ hooked to main RX antenna port and Beverages hook to AUX port,
the same configuration I had for weeks.  As I tune the band, the audio nulls out

about every 0.5KHz where the audio gets very low.  The S meter seems unchanged,
only the audio is affected.  I switched back to Normal receive and sounds fine.
 Then back into Diversity and I get this nulling of the audio again.  Sounds as
if a
Auto notch was enabled, buts its OFF.

The radio has been left for three weeks continuously.  I recycled power without
change.  I am running the latest MCU 4.22 / DSP 2.70 / FPF 1.14, 11-15-2010

I could speculate what it might but I bet this has been seen before.  Maybe a
operator thing but nothing was changed in the radio from the last time I used it

and it worked fine.

Suggestions?

Thanks in advance,
