Well, Tim, 
	My one point here is that RF is not a "Black art".  It is simple
physics that anyone with full attention to detail can understand and
harness for a multiplicity of issues.  You use it or benefit from it
every day, from weather reports which rely on radar, satellite
communications, navigation and GPS, to Television, Cable TV and even
your lowly car radio, along with traffic alerts, and even some forms of
it for certain therapies.

	You probably even cook food with it, and eat food cooked with it or at
least defrosted with it when you eat out.  If you buy shelf stored
goods, it has most likely been treated to reduce bacterial content.
When you purchase something it is a pretty good bet that some portion of
the transaction occurred via and RF link.  If you make a long distance
phone call, you utilize RF.  If instead of light, if NASA published an
Earth at Night using the RF spectrum, it would look pretty much the same
as the one with light.

	People act like RF is some demon in the night, but it is all around us.
The galaxies and stars all generate it all over the place, that is how
radio astronomy works.  As you go up in frequency the physics become
bounded by the ability we have to express the real physical environment
accurately, and people who do not think detail matters always fail in
understanding RF because it is a pervasively detail oriented science.  

	And while I may not have an advanced degree in Electronics Engineering
I have a deep understanding of RF (intensive exposure via the military
and Ham radio let me learn a lot.)  Trust me, we are just beginning to
understand and harness RF.
