[Elecraft] Finished KPA100; problem HiCur and Hirefl

[Don Wilhelm]

Koert,

Make a quick continuity check first - from the center conductor of the 
J1 coax to the center of the SO239 antenna jack.  There should be 
continuity on all bands (the ribbon cable should be connected for this 
test).

Next, be certain R26 and R27 are set at their midpoint.  If the problem 
persists, check T4 very carefully for correct lead positioning and 
properly tinned and soldered leads.  Be certain the red wire goes 
through the center of T4 and the bare wire from the SO239 center 
connects to T4-6.
