Just picked up an interesting piece of hardware on eBay that I hadn't encountered before, an Oscilloquartz 4532 GPS receiver as described here:
http://www.oscilloquartz.com/index.php?pageid=37 It was selling for about the same price that Thunderbolts from China have been fetching, but it uses a nice OSA 8663 DOCXO with 1E-10/day holdover specs. I powered it up with a standard Trimble patch antenna and it appears to be serviceable. The all-important 1-pps LED started flashing green after spending about 30 minutes in various red/green states. However, while the 10 MHz output is clean and reasonably stable (ADEV near 4E-12 at t=1s), it's about 5 Hz too low. Possibly it's using a grossly-incorrect stored position. It looks like the so-called "GUI-based Configuration and Monitoring" software mentioned on the web page will be needed to get the unit to lock properly. Is that available anywhere, freely or otherwise? -- 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.
