I wish it was easier to do things like that... Has anyone made any progress with networking over unliscensed radio spectrum?
Why worry about unliscensed? I believe I've seen a laser (low power Helium/Neon), possibly in the Edmund Scientific catalog, that you can modulate. You'd have a nearly impenetrable, highly directional signal. Failing that, stick to 250mw or less; unless I'm mistaken, that's almost completely unregulated, and certainly doesn't require a license. Lots of hand held CB units, and the Maxon headsets fall in this category. For higher powers, you might consider getting a Ham license, probably at the technician grade. It's true that you aren't permitted to send encrypted messages...but did you know that many hams use SSTV (Slow scan Television) to send still photographs around the *_World_* on long wave (i.e. 10 meter) bands? Of course, only a shamefully irresponsible person would think of violating their duties as a Citizen-Unit (per Mr. May) and use Stegonography to include an encrypted message... You can also legally send unencrypted teletype messages over the Ham waves. Darn modems...sometimes we all have a "bad modem" day when everything comes out garbage. Must be the cables. Regards..
