A long time ago (>15yrs) I did project that for a supply did

Bob, Fluke.1, is selling these on Ebay, for example item # 290313671907,
and supplies the FRS module itself with an interface board containing the
FRS connector, plus another PCB containing a 15MHz oscillator and assorted
other parts that the FRS interface board plugs into.

Hi J
I'm not sure if this has been asked before but don't recall seeing it, does
anybody have a general specification please for the crystal oscillator used in
the Thunderbolt?
I'm interested in the later one, badged Trimble, rather than the earlier
Piezo version, as I've recently bought one of

Hi,
Anyone got a PDF of the manual for this synthized 1GHz generator?
I picked on up but it's about 5 MHz off at 500MHZ and unlocked.
