Well thats a heck of a tidbit to learn.
I built up hack multipliers and such to get some of the old GPS receivers
going.
The best was austron 2001. I did retire it as it was really getting to be a
pain to operate.
You had to know what your doing. Not sure I like that. Neo's have spoiled
me.

These were the typical separate mixer and antenna systems. The first LO was
1500 MHz.
That is an expensive way

Given that the output is not specified into a defined impedance,
termination or even cable-leng
On Peter Vince's topic, *does anybody in the group know what part of the*
*waveforms transmitted by WWV & WWVB mark the second boundaries?*
I was once comparing the timing of PPS pulses from a GPS receiver with
WWV's ticks, and saw about 5 msec delay to the ticks (in south central
Texas).

I was astonished to see the pulse-width in the document defined from the
base of the (sharp-cornered!) edges, and not the mid-point - totally
impractical! Near the top of the previous page it says: "If required for
testing purposes, the pulse width at the 50% level may be determined by
extrapolati
