[Elecraft] setting KPA 100 page 48 problem

[Don Wilhelm]

Christophe,

K13 and K15 should have continuity between pins 2 and 3 also pins 8 and 9
You should also determine that there is an open between pins 3 and 4 
also 7 and 8.
K14 should have continuity between pins 3 and 4 also 7 and 8.  It should 
b open between pins 2 and 3 also between pins 8 and 9.

For comparison with the VFO chart on the schematic key, use the low end 
of each band - 3500, 7000, 10,000, 14,000, 18,000, 21000, 24,890, and 
28,000 kHz.

73,
Don W3FPR
