[time-nuts] Oscilloquartz 4532 GPS receiver

[John Miles]

Just picked up an interesting piece of hardware on eBay that I hadn't
encountered before, an Oscilloquartz 4532 GPS receiver as described here:

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?
