[Elecraft] K3 SSB Audio Issue

[T. David Yarnes]

Hi All,

I have had something rather strange occur a couple of times. 
While I don't get on SSB very much, I have been chatting 
with my friend Jay, W5JAY, on 40 meter SSB on occasion. 
Typically he has indicated that my audio sounds excellent. 
However, a couple of times he noted that my modulation went 
"south", and sounded like I was transmitting through a 
narrower filter.  This occured most recently the other 
evening.  I had not changed any settings that I know of. 
However, the "fix" seemed to be to go to the TX Filter 
setting (which was set for the 2.7 khz filter), and simply 
rotate the dial to another filter and then back  to the 2.7 
khz setting.  That's it!  The problem was solved.  My audio 
returned to its former "excellent" state.  Anyone else had 
such an occurance?
