Hi,Jim said:I assume that you must totally shut the souce down fast, listen for harmonic
then?
[snip]
Only if you're listening for fundamental. A harmonic receiver would
allow for continuous transmission, although it might be easier to
decode an event if the transmitter were pulsed, and that pulsing acted
as system clock.

I tried this once, 'ham radio' days. Two tuned circuits with a diode
between them. Listening for the second harmonic on a shortwave
receiver, I got a definite signal. Maybe 1 or 2 foot range.
