I figure that you could get at most a 40KC wide band segment on a CD for one
hour. Is that right? As a demo of the concept, that isn't bad at all.

And a lot of us military radio people think having a
nation-wide net of WWII BC-611 handie-talkies,
all able to talk to each other in real time, would be an absolute gas.


True. But I haven't yet figured out how the *transmit* side of this would
work.
If you can put up a transmitting antenna, then you could transmit normally thru
it, and your antenna changeover relay would select the Virtual antenna for
receive.

But the walkie-talkies wouldn't be that flexible, and you've noted the physical
and legal problems with putting up any antenna, let alone transmitting.

Would your Virtual terminal include a receiver that samples the output of your
(real) transmitter, (fed into a dummy load?), and digitize that and add it into
the Spectrum that everyone else receives?

Other than dynamic range and bandwidth practical limits, I think your idea has
merit. At least it doesn't belong in the April issue. 73, Mike K. AA1UK
