[Elecraft] 20 meter problem on new K2

[Rich McCabe]

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
