Uncle Sam has multiple hi-power transmitter sites
which can all be controlled from a central site
and used in any combination
(I was a SHARES op and worked them on many occasions).
Each could be controlled independantly for power,
mode, directivity etc.
Given the large spread of frequencies used,
the power levels and, most telling,
the obvious switching between multiple transmitter
locations when I last heard them on 10 MC,
I still believe YS was an excercise in DFing,
probably run for the benefit of multiple agencies.
You've all heard pirates. Compare their flea-fart
transmissions to what you've heard from Sam.
Just one guy's opinion, but an informed one.

I never heard (or read) anything about multiple locations. As best as I and others
could determine is that the signal was (is) coming from northern New Mexico. And
narrowed down specifically to the Albuquerque area.

I've seen nothing much regarding this return to the original frequencies versus the
operation under WWV, but monitoring observations here would indicate that it's
operating from the same general area based upon propagation.
