[time-nuts] Datum TymServe TS2000 Manual now available

Hello Time-Nuts, Greg Dowd, one of the original engineers on the Datum TS2000 (and still with Symmetricom/MicroSemi), really came through! He found a CD with the TS2000 manual, and converted the Word Perfect file to a PDF. With his permission, I have uploaded the file to the KO4BB web site (it

[time-nuts] Sigtec GPS receiver

I've come across an old (2003) GPS receiver made by the Australian company Sigtec Navigation. Although this is old, it has some interest because it's a relatively open design and has been used as the basis for various open source and experimental receivers. It does seem to work (I'm getting NMEA

Perrier, The telecom Rubidiums don't leave much meat on the bone for improvements as they sacrificed pretty much everything else to be cheap, small, and low power consumption. Most of these tradeoffs work directly against trying to get better short term stability out of them. Bummer. Cheers,

[time-nuts] HP 5065A super

List, I've been following the ongoing mod process for the HP 5065A super on the list. Two questions: 1. Are any of these upgrades applicable to the Lucnet and other Rb units? 2. Are there any other Rb units available (that don't cost you your first born child IF they can be found) that could be

[time-nuts] Naked FEI FE-5650A

Well, Corby may have started something. I had the pieces to a Frequency Electronics FE-5650A lying around in a bag, so figured I would share as well. There are two photos. The first is an exploded view with the lamp (not dis-assembled) at the left. In the center is the microwave cavity with
