[Elecraft] K1 Problems

[Stephen Roberts]

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?
