[Elecraft] K3 - NO SSB RX

[Bruce Meier]

Now that this problem has occurred twice it is time to ask if I am alone.

One of my K3s lost all audio on SSB RX.  It still worked fine on CW.  TX was
fine on both modes.  However, if I increased the Width beyond 3.0kc SSB RX
audio came back.  When the Width was decreased below 3.0kc the audio was
again gone.  The problem was not band specific - it occurred on all bands.
This happened last week during the IARU and again about 10 minutes ago.
Last week it occurred while the K3 was powered up and being used.   This
week, when I it was powered on, it came up in this condition.

The fix appears to be a RESET.  (Push NORM - power up - EE INIT) Then I run
the RESTORE CONFIGURATION from the K3 utility program.    The K3 is then
back to normal. 

My concern here is two fold.  1. This should not be happening. 2. This issue
could be the beginning of a larger issue that won't be fixable with a RESET.

Has anyone else had this issue?
