[time-nuts] No GPS satellites

Hi Tom and list,

I joined the list a few days ago after getting my HP Z3801 back running 
after a couple of years of it being off-line.  I'm using it as a 10 MHz 
frequency standard for my various ham-radio activities.

I'm going to have to build one of these.  Assume you have some sort of 
circuit that converts low-voltage AC from a transformer secondary to a 
pulse train, start a timer, and count x amount of pulses?

Very interesting.

thanks much,
