Only to the extent of running a short (10-minute) HDEV test after a ~2 hour
warmup, to see if it was capable of anything interesting near t=10s to
t=30s.  It showed about 2E-12, and the PN was nothing special, so I didn't
do anything else with it.  I'll leave one running for a few days and try it.

They would probably be good for homebrew GPSDOs, given their small size.
Perhaps a Thunderbolt refit.
