[Elecraft] How to demo P3/K3?

[David Gilbert]

Makes sense.

I guess someone wanting a cheap and dirty solution would have to use a 
down-converting mixer and record to a file via a sound card, and then 
mix back to a ham band (assuming, as I suspect would be the case, that 
for a demo they'd be willing to put up with the image and carrier).
