[R-390] WWV Shutdown

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.
