[Elecraft] RX freq issue with ESSB 3k using KFL3A-6K

[N6JW]

Adrian:

I use the KFL3A-6K with "TX ESSB = On" from time to time.  I have 
never experienced anything like what you describe on SSB.

Admittedly, when I have tried it, I usually have the TX ESSB set to
3.2k since I don't have the new DSP board with extended low
frequency TX, but this should not make a difference.

However, what you describe as "receive audio shift" sounds 
suspiciously similar to what we have been noticing with sending
chained messages on FSK D mode (see threads on this topic).
Wayne has just reported, this afternoon, that he has found a fix
and that it has to do with the wrong RX filter being switched in
after transmitting a chained memory using FSK D mode.  Could
you be experiencing something related?  I don't know.  Seems
unlikely, but . . .  let's see.

I will be testing out the new potential fix shortly.
