[time-nuts] GPDSO is working

[Bob Stewart]

Hi Chris,

I ordered a similar one today, along with a 10ft Male-Male serial cable.  I'm looking forward to getting the hardware finished.  I put a ZIF on the VE2ZAZ board, so next I'll probably be playing with the software.  Someone on the list talked about FLL vs PLL with this card, so I'll examine that for awhile.  I have a few ideas I'd like to try out that probably only apply to the OCXO I'm using.

Bob
