[Elecraft] This will effect pilots and Hams throughout the Western US

[Wes Stewart]

How times have changed.  Back in 1997, when I was working as a contractor for my 
old company, Hughes Missile Systems (now Raytheon), I worked on implementing 
some jamming tests on the Tomahawk missile GPS.  FWIW, we put the missile 
section on a wooden pedestal covered in RF absorber on top of the rotating plate 
(also covered in absorber cones) under "The Arc" as seen here:

Just for giggles, I climbed (took the stairs) "The Red Tower", the top of which 
would contain a good sized ham shack.  The tower is completely wooden and held 
together by fiberglass bolts.  The "dish" that is behind the guy being 
interviewed is actually a shaped reflector that in combination with a horn 
located below ground level forms a folded "compact" range, for those who 
understand such things. The leaning airfoil shaped tower holds the test subject 
at the plane-wave focal point of the reflector.  An M1 Abrams tank can be 
supported and rotated on top of this tower.

We had to do our testing in the wee hours of the morning, with secure 
communications links to range people who could tell us to shut down at a moments 
notice and our jammers were on a, few minutes on-lots of minutes off schedule.
