My friend with Falcon Reconnaissance and a ham for many years has been telling me about sending code data as far as 10,000 miles with a 1mw transmitter. Simply a matter of the receiver filtering out with hi-speed digital precision everything except exactly the signal it's looking for, eliminating everything else.
Yup, that sounds right. Pretty astounding,
isn't it?
I remember being shocked about the
Yoyager probes that were sent out in
the early 1970s. I think those spacecraft
only ran about 10 or 20 watts. I know one
of them has finally left the solar system -
because it is not detecting the solar wind
anymore.
I'll have to look that up. That's pretty amazing
too. That spacecraft must be 2 or 3 billion
miles away now. And yet the Deep Space Network
is still hearing it.
Well, I THINK anyway.
