[Elecraft] K2 with no TX or RX help please

[Don Wilhelm]

Denis,

 From that information, all I can say with certainty is that the problem 
is somewhere inside the enclosure :-) .

My first guess is that one or more of the connectors on the option 
modules has developed a bit of oxidation during its period of non-use.  
I would remove and re-insert all the option modules.  If you have the 
KAF2 or KDSP2, I would start with that because it is directly in the 
audio path, then proceed to the KSB2, then the KNB2, then K60XV if 
installed and lastly the K160RX.

If that does not help, please give a more complete description of what 
you hear on RX - for example, do you hear receiver noise if you turn the 
AF gain up?  Does the noise level change with the preamp and attenuator 
in and out?

73,
Don W3FPR
