I recently bought 2 LPRO-101's. The first worked perfectly, locking up
within 5 minutes.
The second one would not lock within 15 minutes, so I returned it (to China)
for a replacement. As I didn't have a heatsink, I didn't want to leave it
any longer. Besides, if it doesn't lock within 5 minutes, then I assume it
is faulty. Instead of the frequency sweeping up & down, the Xtal volts
started at around 6V2, then swept down to 0V & stayed there, leaving the
frequency about 180Hz low, as seen on a HP 8591E analyzer.
Out of interest, did your unit sweep up & down, or was it similar to mine?

I fired it up last night and it took about 2 hours to lock.
This morning it only took about 20 minutes to lock.
I guess I need to stir the electrons a bit more ??
It's sitting there on the counter, with a 1000 sec Gate time
and it is as accurate as I can measure (BTW, the counter
reference is a GPSDO - TrueTime).
Looks like a keeper.
