I just picked up a Star Box for $10. It has an Allstar DGPS board inside. I
saw several mentions of similar boards in the archives and I have found
some documentation on the net. Has anyone actually used one of these in a
GPSDO? Does it work any better than the usual Motorola, Rockwell, or other

Hi Bob,
No biggie - just wanted to make sure I was calculating it right! :)
Thanks,

This is how I calculated it:
13939010/13939 = 1000.000717411579022885429371
answer/1000 = 1.00717411579022885429371
answer-1 = 7.1741157902288542937083004519693e-11
answer*1e9 = 0.071741157902288542937083004519693
Thanks,

Hi
So your Rb is 0.71 ppb off frequency.
That's far enough that's it's worth adjusting. You should be able to get it 10X
better than that without a lot of work.

I think they were only intended as a backup if the XO section or GPS
failed. The XO section does discipline but I don't know the details.

Hi Chris,
I've posted this before, but it's worth saying again. I use the PocketPC
version of Lady Heather on an IPAQ. These are available for next to nothing on
Ebay and can run in a dock on the bench or you can gut it and embed it in a
cased Thunderbolt. worn out batteries are not an issue as
Yes, but not for technical reasons. I'm opting to build my own for the $15
in parts. Not quite free, but at the same time this isn't new to me and it
won't take long and I'll probably learn a little.

Hi Everyone,
I've only got the RFTGm-II-Rb module. I found an interface cable

The fundamental issue was that the same code that worked elsewhere could
not decode the 0x8F-AB packet data 100% of the time. I saw the length of
this packet vary by a few bits at the code level, so I used a logic
analyzer with serial decode to examine the raw data coming in to the
