Several States Have Made It A Criminal Offense
To Broadcast With "PIRATE" Radio Equipment
What does the FCC say about penalties
for operation of unlicensed equipment?

The Commission considers unauthorized broadcast operation to be a serious matter. Presently, the maximum penalty for operating an unlicensed or "pirate" broadcast station (one which is not permitted under Part 15 or is not a Carrier Current Station) is set at $10,000 for a single violation or a single day of operation, up to a total maximum amount of $75,000. Adjustments may be made upwards or downwards depending on the circumstances involved. Equipment used for an unauthorized operation may also be confiscated.

There are also criminal penalties (fine and/or imprisonment) for "willfully and knowingly" operating a radio station without a license.       DON'T DO IT!

Using Non-FCC Approved Equipment
in New Jersey and Florida is now a CRIME
