Of the longwave radio frequencies used for time standards, 40kHz (JJY,
Japan), 77.5kHz (DCF, Germany) and 60 kHz (WWVB and MSF) crystals are
off-the-shelf items in the Digikey catalog at less than a dollar each.

Really...! Hmm... perhaps time to re-visit the "WWVB receiver using op-amps
and a small microcontroller" ida? One of the regular contributors to
Circuit Cellar Ink tried it a while back (4 years?), but wasn't successful.
A successful project would be worth a write-up in some hobbyist magazine (of
what's left... Nuts & Volts seems to be about it in the US...)

Anyone know which time service folks in Oz or the Kiwis use?
