Re:Get an Amateur Radio License (Score 1)

Excellent advice (glad someone thought of it). There are many digital modes available in the Amateur Radio Service. It would provide an excellent learning foundation on Spread Spectrum and other modes as people have already listed. The commercial nature of the traffic, or it's encryption, cannot be broadcast in the spectrum allocated to amateurs, but you will sure find lots of people with encryption experience from the commercial radio side within your hobby. Maybe look up your local amateur radio club and ask around...
