[Elecraft] K2

[Don Wilhelm]

Andy,

Is this a K2 with the new VFO encoder?  In other words, does the encoder 
have a board attached to it?
If so, your problem is that the encoder board is touching the leads of 
the Control Board behind it.  Flush trim the encoder board and the area 
of the Control Board behind it.  I mean really *flush* trimming the 
leads, there is no extra space.
You might even put some insulating material (fiche paper) between the 
encoder and control board.

The only menu entry dealing with 40 meter VFO operation is the secondary 
menu D19 entry.  That should be set to "N" if the K60XV option is *not* 
installed (nor the Rework Eliminator wiring for the K60XV) - if that 
option *is* installed, set D19 = Y.

If you have the older encoder and the D19 menu setting is correct and 
the problem is only on 40 meters, do you have the KPA100?  If so, does 
it have the speaker magnet shield?  An unshielded speaker magnet in the 
KPA100 can interfere with the operation of relays K13, K14, and K15 in 
the base K2.  Remove the KPA100 and see if the base K2 behaves 
correctly.  You may need to upgrade the KPA100 shield with KPA100SHLDKT.
