Hi Steve,
Is the problem on both 20 and 40? If only one band check the band
crystal on the filter board.
C2 on the filter board is a fixed cap - no tweaking! ;-)
Also check connectors J6 and J7 on filter board. Bad connection - use
some DeOxit5 cleaner.
Start with alignment according to the manual, if you haven't done that.
Good luck!

I'm suddenly out of a signal. I get hiss but no signal. I'm using a k1 fil 2
40/20 board.
I was getting weak gain on the 40m side so went in to peak the L1/L2 L5/L6
Inductors.
I messed about with them but was unable to peak them as I heard no change in the
volume of the hiss.
I also tried C2 Gain tweak and not joy there either. I hear no change in the
hiss volume
as I turn it.
I rigged up my 7300 with a dummy load and xmitted on 7050 and 14050 and heard a
signal
but still no effect by changing L1/L2 or L5/L6
I pulled the band board looking for any issues with soldering or whatever and
found
nothing. Put the board back in and now I get zip. No receive at all, just
hissing.
It was working fine yesterday although I felt the gain was very low and needed
adjustment
which led me to this point in time.
Suggestions on how to get it going again?
