I can just see the Marshalls riding around in a panel van with a radio direction finder on top, homing in on the State Kriminal.
I think shortwave broadcast is licensed,ANY transmitting requires meeting rules as set forth in the CFR (Code of Federal Regulations, specifically, the 'FCC rules and regs') and may require proper licensing AND requires the use of 'Type Accepted' equipment.
Many of these 'militia types' have taken to using Amatuer HF radios to do their own 'broadcasting' just above or below the 40 Meter Amatuer band - this band has good propagation characteristics and a minimal antenna (simple dipole) and a 100 Watt radio can achieve surprising results ...
Most of these would-be pirates wanna immitate Alex Jones and his *legal* (although insane) broadcasts on 6890 KHz.
The difference here is - Alex legally purchases his airtime from WWRB ...
