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
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.
