[hpsdr] [GIBRALTAR] An interesting link on frequency locking and GPS disciplining

[Rick Hambly (W2GPS)]

Alex,

For (c) I suggest that provision be made for both 5 and 10 MHz inputs.  Many
of the best Rubidium, Cesium, and Hydrogen Masers have 5 MHz outputs. I use
a HP5065A (5 MHz) Rubidium steered to GPS with Tac32Plus, a Time Interval
Counter and a front panel control.  It is so stable that it takes a month's
worth of data to develop a calibration profile and it does not suffer the
discontinuities associated with electronic steering.  I distribute the
output all over my lab.

I think the answer is yes. It's a widget, we can use it for anything on the
presentation. 
I think GIBRALTAR will have a few options:

(a) OCXO - either buy a surplus one, buy a new one, or roll-your-own
(althought we might have a G8ACE-derived on onboard)
(b) GPS - either use the Trimble Resolution-T or get redundancy with the
iLotus M12M
(c) Plug in your own reference and not use GIBRALTAR

The RSGB slide presentation "Using GPS in Amateur Radio" looks
particularly interesting in trying to figure out just what we want
Gibralter to do. Which use cases do we want to serve?

I spotted this link to G4JNT's website on another SDR-related listserv.
