I've tried calibrating with WWV, but I get about 2-3Hz doppler drift
here in the east, so I bought a Nortel GPSDO, plus it puts out 10MHz
that I can feed to my Moto Service monitor and also my TS-2000. I bought
a little circuit from OZ that does that for some rigs. Trouble is the
DSP is off by about 1.7Hz The new digital TV stations put out a GPS
locked carrier signal, but some are offset by a small amount.
I used to work at Goddard back in the 70's, right next to the towers for
WWV. There had those big Amperex multi channel recorders from satellites
that one track was dedicated to the WWV signal. Somewhere I've got a WWV
QSL card for the time they switched to Ft.Collins. I remember even back
then some of the technicians thought the moon walk was faked.
Don't know what a new GPSDO sells for these days but I would think one
could be had for $100 or less? I've got a Rb standard, LPRO-101, if
anyone wants to buy it pretty reasonably.
