I think you are limited to the old Motorola Oncore type. The UT+ sells for about $15 on eBay. There are two versions of the UT. Get the timing one. These aren't to bad. The PPS one sigma error is about 50ns and the UT runs on 5 volts. The newer MT+ version is better but at least $30. Does it make sense to place thermal insolation on a TCXO? It does on an OCXO because there is a thermostat inside the device and the thermal insulation will help the OCXO maintain a constant temperature. But a TCXO will just run hotter. I think all you need is a box to keep drafts and direct sunlight off the TCXO. -- Chris Albertson Redondo Beach, California _______________________________________________ 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.
