Ray –

A Cesium would be an overkill. Besides, the cost for a new one would be extremely high and a used on more than likely has a tube that is dead or depleted. A Rubidium is a lot more cost effective and lasts longer. BTW, there are distribution amps for video that are pretty cheap on eBay. You can get about 12 outputs from one. They are also 75 ohms, but that is not a bid deal for most equipment. I bought several of them years ago when I was into the “time-nut” mode. I also have 3 or 4 Cesiums, and dozens of Rubidiums. 73 – Mike

Subject: [MRCA] GPS disciplined oscillators

Not relay looking for big improvement or anything with the big Harris radios, just maybe trying to find another reason to justify the purchase and next building of the distribution for the box. Have a Motorola service monitor and Agilent spectrum analyzer that I use all the time and think they are accurate to within maybe ten or one hundred cycles and not wanting to send them out for annual calibration I figure that with this box I can get to one cycle or so that would be good.

A Cesium Beam standard would be perhaps the coolest method, but a  GPS disciplined oscillator got to be next and way better than my old method of beating the oscillators against WWV.
