Two way radios

[Moristans]

If you're REALLY serious you could get a HAM radio license. I don't think the requirements are anything like what they used to be, although I'm sure it's still a step above going out to the store and buying a radio and antenna.

We had a HAM radio operator in my neighborhod when I was a kid. He pissed everybody off because our TV rabbit ears would pick up his signal.
