Suggest getting one of these, or another one like it: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180419218430 There are several cheaper ones for sale but make sure you get the 3.00 firmware and Trimble-labelled OCXO if possible, as they are better performers than the older ones. E.g., avoid item 290308733659 as it's not doing well in either the phase noise or ADEV departments, going by the photos he's posted. -- john, KE5FX _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
