There's a seller on eBay selling what he says is Z3801A upgraded to 58503A. One or two things have made me a bit suspicious of that seller - nothing to do with his GPS things. Does anyone know what he does? He also have an 58503A, but that's a couple of hundred $'s more than an upgraded Z3801A.
I've been thinking of buying one of the Jackson Labs devices, which is obviously a more modern design, but I'm giving some consideration to buying a used GPSDO with an OCXO, rather than a TCXO. By the time I purchase the TCXO based unit, stick it in a box, build a buffer, add a power supply etc etc, it is not going to work out a lot cheaper than buying a used OCXO device. My mind is not made up about this. There are advantages and disadvantages of both.
