[time-nuts] New WWVB modulation format receivers (NOT)

I have a wave analyzer which for those who may be unfamiliar with such an 
instrument is a super het receiver that tunes from 0 to 50 kHz.  Mine has 
enough extra range on the high end to hit 60 kHz.    I can connect a 40 foot 
wire antenna in my attic to its input and receive WWVB here in Kentucky.  I 
can see the variations on the meter or look at the frequency restored output 
on a scope.

Regards.
