Conrod, Sorry to hear of this issue. Really, it should not be a question. Where I fly, our frequency procedure calls for posession of the frequency clip before turning on the transmitter.

The only incident I have ever seen, where someone turned on a transmitter and shot someone down, involved two Ham operators. These guys can choose one of the 50 MHz transmitters, rather than the 72 MHz units the rest of us fly. The culprit was simply unaccustomed to having to look out for other 50 MHz guys, since he was the only one at his other club. When he turned his Tx on at his alternate club, there was another Ham operator taking off - on the same channel. His plane crashed at the end of the runway. Unfortunately, he had just finished repairing it from a prior crash.

The culprit was very apologetic and paid the other guy immediately, no doubt very embarrassed by the situation. It was a bad situation, but not nasty. Everyone understood what had happened, and all hope to never be involved in a similar case.

Good luck,
Dave Olson
