Hello Albert,

I was attracted to the Temic wwvb/dcf77 receiver chips because they
draw 30 microamps...so, a receiver that draws 4 microamps is indeed
low power and is very promising.

AFAIK many "atomic clocks" listen to WWVB briefly and then turn off the
receiver again. With a very low on/off duty cycle the power consumption
of the receiver wouldn't matter so much.

Regards, Joerg
