Hi Magnus,
Thanks for your further comments. As you probably saw in my reply to Mark
Sims, I am proposing
to check the swing limits 'before and after' inverting the unit, to check
out the theory before I open it up and try tweaking C217.
Cheers,
Jim

Hi Magnus,
Thanks again for those further suggestions. I do have a GPSDO, and I had
been able to use it with a counter to check that the FE-5680A was
swinging either side of 10MHz. But I didn't make sure that it was
swinging evenly each side of 10MHz . According to my notes it was
swinging between 9.999770 and 10.000036MHz -- i.e., about 230Hz low and
about 36Hz high. But it was spending more of the time below 10MHz than
above -- does this suggest to you that I should tweak C217 until it
swings by about the same amount either way?
Yes, that is exactly what I would do.
Cheers,
Magnus
