Since this occurs only in SSB, the problem is on your KSB2 board.
1st try receiving with the SSB filter set to something other than the
OP1 filter. If my current guess is correct, the KSB2 firmware is not
switching the filter properly - and if that guess is correct, it will
receive when the ba
Doing a Master Reset is not a step to be taken lightly. It will wipe
out all your menu settings including your CAL PLL and CAL FIL settings.
If you feel you need to do a Master Reset, write down all your menu
settings beforehand so you can restore your K2 after the reset. Don't
forget that t

Fixing it by changing bands and weak reception afterwards is the key to this.
No SSB is also a clue. I would say you have a problem in the switching
between TX and RX. It is not the RF side of things (e.g. switching diodes)
as it would not reset, it must be in the control signals. Somehow the +TX

Tony,
I have never seen a problem like that before, but I would suggest
starting with the 8R and 8T voltage rails on the control board. If they
are not switching properly between transmit and receive it could
conceivably create a problem like you describe.
OTOH, hearing your SSB signal in t

ask on here in case someone has seen this problem before.
It receives fine on all bands. When I transmit (does not matter what power
level or what band)
