[Walter Shawlee 2]

Hans,

I have yet to see a manual anywhere for these references, but they 
consist of the "cal" generator (0dBm) from the 435A power meter, and a 
10544A OCXO for the frequency reference.

in my -K26 units, the 15 pin (double sided) pcb connector takes a 10544A 
OCXO.

it's possible that EFC (via a trimmer pot) is added in your variant. can 
you install a 10544A?
is the power/return wiring correct?  that may allow you to figure out 
the rest.

regards,
walter
