I have a 58503 that occasionally is not able to track satellites. Usually I wait until the holdover expires but then the only fix seems to restart the 58503 (SYST:PRESET) better than power cycle. It seems there is a command to reset only the GPS receiver but it is not in the 58503 manual. On Tue,

[time-nuts] FE-2266A oscillator data

2013-07-16 Thread cdelect
I see an FE-2266A oscillator (120Mhz) on eBay. Does anyone know what it was used in. Just wanted to see if the pinout and power supply rating could be determined. I'm looking for a 60Mhz or 120 Mhz OCXO preferably with EFC Thanks, Corby ___
