To be more precise, the guest was Tom O'Brien, Chief of the NIST Time and Frequency Division. In any case, I should have known the message would not propagate out the list in time for people to catch the live broadcast. Surely there will be a rebroadcast and/or webcast available soon, though...

The OXCOs are identical on the schematic, but pinout patterns vary. At least mine did, which can be cobbled around, but not fun. Pete Rawson On Sep 24, 2010, at 6:18 PM, Bob Camp wrote: Hi The new-er ocxo's are available on the e place for about $50. Replacement tbolts are $60 to$120 on
