Re: [time-nuts] PPS sync

That makes complete sense, it’s not disciplining anything, just pumping out the PPS and reporting the variance. I don’t know why I didn’t think of it. It’s interesting how it jumps around from PPS to PPS. Thank you, Jerry > On Jun 7, 2017, at 2:57 AM, Hal Murray <hmur...@megapathd

It was off 7.5KM, that’s a little beyond groggy, no? More like a trip to Vegas. I’ll let it rerun the survey and see if it gets closer. > On Jun 4, 2017, at 9:50 PM, Mark Sims wrote: > > Be careful when using one unit's location to set a different model's > location...

Greg, Funny. Some of the lucent boxes have been in strange places as well. Can you please check your PPS to see if you get a signal when in that other mode (where it needs at least one sat locked)? > On Jun 2, 2017, at 5:13 PM, Gregory Beat wrote: > > Received a note from

Re: [time-nuts] The future of Telecom Frequency Standard surplus

Tom, Another question is will the surplus equipment have the same value to the hobbyist? I have a lot of old gear like spectrum analyzers, scopes, signal generators, etc that was outdated and sold for cheap. I keep wondering if the same economics will apply to the equipment that is for

Re: [time-nuts] GPS Kit Plates

Greg, to which adapter cable are you referring? From the PC to the DB9? What I did in the meantime was use breadboarding jumpers. The square female ends typically will press onto the DB9 male pins. Glad they fit your need. Steve, sounds like there won’t be another round? Jerry > On May

You shouldn’t have to enlarge the holes. I trial-fit the lenses from the unit I received in the holes that I drilled to specifications in the document at approximately .28”. The lenses add a professional look to the front plate. Jerry > On May 21, 2017, at 3:42 PM, Steve - Home <st
