[time-nuts] nuts about position

I did another test to see if the M8T offered any positioning advantage over the old (and cheap) LEA-4T and LEA-5T devices. I drove the M8T and LEA-4T with the same antenna, collected data for 12 hours, beamed the RINEX files to Canada. The results matched to within 3mm... so, again, the M8

Hi We ran 5335’s in “long gate” mode via the gate open / gate close commands. It worked, but you had to compensate for rollovers. My guess is that you would run into similar stuff on the 5370A. Simple answer is to try it and see … That’s what we did on the 5335 and then worked through all the

Re: [time-nuts] HP 5370 A to B conversion?

HP once offered a field conversion kit. One of my 5370Bs began life as an A. I believe that it was mostly in the firmware. John Seamons, j...@jks.com, developed a replacement processor board that uses a BeagleBone Black or BeagleBone Green to emulate the 6800 processor of the later 5370s. (Ear

Re: [time-nuts] HP 5370B using manual start-stop
