there are others. depending on acceleration and duration, GPS + APRS
tracking can be unreliable. it seems most COS parts fail at over 15Gs
acceleration; the ITAR limits come in at 6 feet and/or mach 1.
so, additionall
not at all. read the summary, they are playing with group delay.
oh and by the way, there is some effect working with "cold fusion". we
don't know what it is.
that's why it's called basic research. "if we knew what we were doing
it wouldn't be called research"
one more thing, people need
that is awesome! with "Transistorized Binary Unit" and up to 1.1
megacycles. wow!

Nice photos. Thanks. GAS building up.

two thumbs up for Radio Shack - they sure have their problems but they
are all we have in a lot of places. with the new Velleman and Arduino
and Basic Stamp kits, they are clearly trying. they have a ways to go,
but I try to vote with my $$$ a little bit. Cliff K6CLS

It seems that a commercial venture is driving this. Probably with all of
the research at taxpayer expense.

wow, in the document - this really bothers me
First and only receiver for the new WWVB signal (
