[Elecraft] K2 deaf on 40 m

[Don Wilhelm]

Svend,

Is this a newly built K2, or one that used to work and has now failed.  
Do you have the K60XV option?
If it is newly built, check to be certain you have installed C6 (on the 
bottom of the RF Board near the rear panel) correctly.  Its leads should 
be in the outer holes of the set of 3 holes between L1 and L2.

If you installed the headers for the K60XV option (or the rework 
eliminators), you must insert the board into J15.  Does it receive on 60 
meters?

If this is a K2 that worked before, there is likely some failure in 
either in the Bandpass Filter or the Low Pass Filter.
Does it transmit on 40 meters?

73,
