Rick,
All the Spectracom WWVB and GPS receivers use the same serial protocol;
I have had one or more of these things running for almost 30 years. The
Netclock/2 is useless without its ferrite-stick loop antenna, and even
then the rising noise pollution due to the noisy electrical grid and
machine room UPS systems have rendered any WWVB receiver essentially
useless. An ironic fact is that my WWV receivers now outperform the wwvb
receivers and both are much inferior to a GPS receiver. Considering the
sometimes difficult problem of finding rooftop real estate for a GPS
antenna, a CDMA receiver, such as the EndRun CNTP, might be now the
easiest to deploy.

So, in a local "on its way to its final reward" pile I have come
across a Spectracom Netclock/2 and am wondering whether it might be
worth saving from the scrap heap. It does power-up and shows a time.
Unsurprisingly I suppose since it has no antenna connected and I'm in
an office building, the Antenna, Signal and Time Sync LEDs light red
:)
