Time-nuts,
Seems like a bad batch of HP10811's was dumped on e-bay over the holidays... Some (at least
2) won't tune up to 10MHz: one won't adjust above 9,999,530 and the other peaks around
9,999,920 after warming up for a day or so. It seems to stay on frequency (albeit the wrong
one...)
I did some preliminary checks (internal reference voltages, OK, etc.) I'm thinking that it
must be a bad crystal to be this far off.
C'est une cause perdue? (I.e. did I buy a "parts" unit?)
