[Elecraft] K1 No power out on 2 of 4 bands

[Don Wilhelm]

Kieth,

Glad to hear you have it working.

If your reception gets louder by just gently touching the top of the 
case, I would look for a problem in your antenna system - likely a 
broken shield connection in the coax.  OTOH, if it takes a solid tap to 
change the volume, I would look for the unsoldered (or badly soldered) 
connection in the K1.  If you are absolutely certain it does not happen 
on 40 and 30, then the bad connection would likely be found on the 4 
band board.

As far as the frequency coverage, re-do the VCO adjustment 
(spread/squeeze the turns of L1), and place the VFO frequency as close 
to 3090 kHz as possible - but not below that frequency (that condition 
must be satisfied *after* you tighten the nylon screw).  You may be able 
to achieve the proper adjustment simply by moving the last turn of wire 
without loosening the L1 mounting hardware.

73,
