[time-nuts] FE-5680A won't lock

[Bob Camp]

Hi

I had the same issue with one unit (out of three) from the same seller. As
mentioned elsewhere, it locked up after about 20 or 30 minutes on power. It
seems reasonably stable and does not pull excess current on either supply
rail.

Just got my 3 in from nichegeek.  Paid Thursday, shipped Friday, 
arrived this evening.  Wow.  (Actually arrived too quickly--I don't 
have my t-bolt running, so I can't easily do an accurate frequency check.)

Two power up and lock in <3 minutes.  One powers up, gets toasty, and 
gives 10MHz, but no lock and no PPS.

The tuning config on all three read back as 0.  I've set the problem 
child to near +/- FS and about +/- 25% of tuning range: still no lock.

Any suggestions on what I should look for or try?  I'm not quite 
ready to throw in the towel and contact the seller.
