Must agree strongly with Niteflite .It was Thanks to a genuine Radio Amateur who managed to record some of the 'interferers' transmissions and help get a solid case for conviction.
The person in question was calling aircraft on an operational frequency and asking them to change frequencies to 123.45. Once the Pilots realised what was going on they quickly changed back. His stupid actions could have resulted in a vital genuine ATC transmission being missed.
This person should have received the strongest punishment possible and be made an example of . There should also be some action taken to prevent the sale of airband tranceivers to the general public before something occurs with a more tragic outcome
