Re: [time-nuts] The Symmetricom GPS Antenna's (Export licenses? are there any needed?)

Does anyone know of any issue with licensing (export licenses) for these? I seldom hesitate to ship old computer stuff I have, but that GPS is technically a military tool gives me pause to step up. The vendor may have such things ironed out, but individuals that step up here may have a hassle

Re: [time-nuts] KS-24361 REF-0 standalone

Hi If indeed you are into a professional system, where holdover matters then a lashup on a bunch of surplus gear likely isn’t going to measure up. Based on about 10,000 previous posts on the list I’d say that holdover does not appear to matter to Time Nuts. It would be difficult to find a

Re: [time-nuts] The Symmetricom GPS Antenna's (Export licenses? are there any needed?)

Hi These antennas are in the same league as a automotive GPS. Since they don’t even have the GPS receiver in them, they actually have fewer regulations on them. As such there are no restrictions on exporting them. That said, I don’t think I would ship anything (even a bottle of milk) to some

Re: [time-nuts] KS-24361 REF-0 standalone

Hi There are a number of papers out there (check the NIST archive) on GPS vs Gloanss timing. The simple answer at this point is “don’t bother”. Bob > On Oct 3, 2015, at 1:28 AM, Hal Murray wrote: > > > kb...@n1k.org said: >> The main thing you get with the 7’s (vs

[time-nuts] Symmetricom sa.31m serial protocol

Hi. Sorry for messing up the last post. I try again: Does anyone have the specification of the serial port protocol for the Symmetricom / Microsemi sa.31m ? I could only download the datasheet which does not give any information on the syntax or the available commands. Thanks in advance, Bernd

Re: [time-nuts] Looking for ECL divide by 3 with symmetry

After studying the various divide by 3 circuits, I decided to try designing one that would be simpler in terms of package count, using available ECL DIPs on-hand. Instead of the JK-FF version followed by duty cycle-fixing circuitry, I opted for two 10131 dual D-FFs to provide the state

Re: [time-nuts] KS-24361 REF-0 standalone

Dan it looks like the thread has re-developed. As my early test of your simple solution demonstrated. Better PPS better stability (Used a TBolt to test this) in the form of semi-short term jitter. The beauty of Dans solution is the user can select the quality and cost of the receiver used.

Hi, would anyone here have a user manual for the TM7000 unit as a pdf? Or the configuration software for the RS232 port? Thanks Linden ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to
