Steve,
The quickest way to do the alignment is to use an RF Probe or an
oscilloscope with a 10X probe.
First probe band board P1 pin 6 and peak for maximum RF on both bands.
The can be done in receive.
Then connect a dummy load and do a TUNE at about 1.5 watts.
Connect a probe to band board
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.

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
