[time-nuts] New GPSDO on EBAY From China

I remember seeing this same unit here on this list some weeks ago.  As I
remember it is built from some plans that were published.   You can see
that it uses a surplus OCXO.  The seller is good to claim the specs of his
GPSDO as being "two orders of magnitude above the OCXO".  because we don't
know what surplus OCXO this unit will be shipped with.   If you just want a
low cost GPSDO you can build one for maybe $50 total and then it is
repairable and should last "forever".  If you want predictable performance
you'll have to buy a name brand commercial unit.  This Chinese built unit
looks to be aimed at someone who needs a lab bench reference to keep his
frequency counter on calibration and does not want to do any soldering.
