Hi guys,
Today I received a shiny new (to me anyway) FRS-C Rb from one of the usual
sellers in China. It locked after roughly 2 minutes. Comparing it to my
Thunderbolt I saw that it was running at a very slightly different rate. I
adjusted the c-field pot and made it slightly better but I ran out of range
on the pot! It's fully counter-clockwise and one trace is moving past the
other very slowly. I can speed it up by turning it all the way to the
right but it never stops or changes direction.
Is there anything I can do that isn't too difficult to remedy the
situation? Should I let it warm up overnight before messing with this? (my
other unit does not have this problem -at least it didn't before I killed
it).
Thank you for any suggestions,
Bob
(ps, the thunderbolt has been on for over a year so I don't think that's the
issue but I really don't have any way to verify it. Lady Heather thinks
it's okay.
