[Elecraft] K2 Lo p on 10 12m when its cold outside.

Ed,

Since those easy steps did not reveal the problem, you will have to 
resort to some Transmit Signal Tracing to find the problem.
Use the stage-by-stage points shown in the manual Appendix A page 14 
starting at the middle of the left column.
BUT you will have to deviate from the instruction to set the K2 on the 
40 meter band - use a failing band instead.
If the measured RF voltage is greater than the expected value, that is 
OK.  What you are looking for is the 1st stage in the sequence where the 
RF voltage is significantly *less* than the expected value.  That is the 
output of the failing stage.
