Me too.

I have two 545A's, one of which works and the other of which has issues with
Band 3, failing to read in a very interesting pattern suggesting a YIG
filter issue, probably the control circuit.

Just no time to chase it right now.

Please post the resolution.

I have an EIP counter with a problem, stashed, that I need to look at 
eventually. So have been following the thread a bit.

If you guys get somewhere conclusive (or not), might be nice to post a 
summary of all important details, techniques, or circuit notes beyond 
the manual, found, to this thread for closing to posterity searchers. 
(And me.)

And, in the mean time, good luck, bon debugging.
