[time-nuts] Degaussing Unit For An HP5061B

I am looking for an HP 10638A degausser for an HP5061B Cesium Beam Standard.   Does anyone have one that they are willing to sell?   Short of that, does anyone have a schematic for the degausser they're willing to share with me?   Thanks!   Jeff Jeffrey K. Okamitsu, PhD, MBA +1-609-638-5402

Re: [time-nuts] Degaussing Unit For An HP5061B

I've been looking for one for ages. They're out there, but at outrageous prices. ManualsPlus sells a very nice reprint manual with schematics. If you're patient, I just started building a replacement using most of the original circuitry. I'd be happy to make board files available, or a board

Skip, I've successfully converted my TS2100 IRIG to a GPS model along with several other people. As far as I know, the Oncore module was never used (maybe a planned future upgrade), but the ACE-III modules work just fine. The trick is you need to make a temporary interface with your ACE-III and

Gerhard -- the discussion between you and Bruce has been very interesting. I asked a VLBI colleague to look over your design and he had this comment. In VLBI, H-Maser frequency standards used to generate local oscillators at microwave frequencies. We have problems with amplitude

[time-nuts] Naive question on WWW stations

Hi, I listened today the WWW station and I've found it on 9.996 Mhz instead of 10.000Mhz and my receiver is fairly well calibrated and I was within the narrow CW filter. I thought the WWW was precisely on 10Mhz. Do you have some explaination? How many WWW station worldwilde are there and what

In message [EMAIL PROTECTED], Gerhard Hoffmann write s: The question is more if the 100r * 100u do anything to de-noise the LED voltage. Close to the carrier probably not. The problem is that you nowhere get exact numbers to base a decision on. Be aware that LED's work both ways: current-light

Re: [time-nuts] Naive question on WWW stations

You don't normally listen to a CW signal at zero beat, so many receivers apply a BFO offset to make the CW tone audible at a comfortable frequency. This is usually more like 800 Hz than 4 kHz, though, so you could still have a calibration error somewhere. -- john, KE5FX -Original

Re: [time-nuts] Naive question on WWW stations

You heard the Russian station RWM (.-. .-- --) which transmits on 4996, 9996, 14996 and maybe 19996. It is the easiest to receive station in Europe, quite strong signal. 73, Antonio I8IOV Hi, I listened today the WWW station and I've found it on 9.996 Mhz instead of 10.000Mhz and my
