Re: [time-nuts] WWVB paper in May 2014 IEEE communications...
I guess several comments here. I checked the xtendwave web site and its alive. But noticed no press releases or anything since last year. So sent an email just to see if it bounces back. Yes indeed since the great new formats sort of useless. Wonder if NIST could simply turn it off the PSK and go back to the old format? Gosh that would be the end of the d-psk-r project. But all of the old phase tracking receivers would work again. On the chips there was a time-nut who had I think 25 of one of the chips very reasonable in cost, and the other chip was still available at least as samples from the manufacturer. I posted that some time ago on time-nuts. Or easier to build was the receiver and that I shared and a search of google reveals others. So getting a 60 Khz rcvr in some aspects very do-able if you have a soldering iron.

[time-nuts] Oscillator help
I have a board marked DMEC M1 Supply that contains a Toyocom TCO-929A oscillator. This probably came from some type of small aircraft navigation equipment. The oscillator has a date code of 8922. It has 4 pins and a trimming capacitor on the side. The frequency is 10MHz. From the part number I would guess that it is temperature controlled. A search shows nothing for this part number. Does anyone have any further information on his oscillator as to stability, accuracy or similar?

Re: [time-nuts] combining same frequency for redundancy
Quoting Tony Greene tonygreen...@inbox.com: About 50 years ago I ran into a Frequency Division Multiplexer that used a redundant master frequency system. I beleive they combined the same frequency for the master oscillator, but it was something like a special hybrid combiner. I remember that they used a phase angle of 135 degrees - and then if they lost one signal, the power went down by 3 db on the main pilot. Anybody no any details on this type of system ? What I am looking for is to have an input to a distribution amplifier where I can connect and disconnect two different inputs and keep the output systems up and running. It seems that the HP 58502A distribution has this feature : From the documentation : The controller block input select line state (at power on from the factory) selects input A over B, if valid signals are present at both connectors, but will switch to input B automatically, if the signal at input A fails. If input B fails and input A signal reappears, the controller block will select input A again as the valid input signal source. If both inputs fail, no select line state change will occur. Claude.
