I would forget checking relays for the moment. Take a look at the coupling
capacitors for the 20m/30m circuit, the ones installed on the bottom of the
board. Make sure solder flowed through to the top of the board for good
connection to the traces up there. This was my 20m problem.
73, Joe, aa4nn
I just noticed that my K2 build 43xx is almost totally dead on 20 meters. I
think all the other bands are OK.
I hooked up my N-Gen and could not hear anything on 20. I thought I could
use a scope to follow the generators noise signal but the scope makes
about as much noise as the generator when going through the bandpass
circuit.
I am guessing it is probably bandpass or low pass and I need to start
checking to make sure the relays are making contact, etc.??
It worked when I built it a couple months ago and am not sure when it quit
as I dont use 20 often. This K2 is totally optioned and I have removed
the 100 watt PA to make sure it is not the culprit.
Any comments on the best way to trouble shoot this?
Thanks and 73,
Rich
