including honking a horn and seeing if the camera picked it up.

We did this once when trying to find someone's house who was transmitting on a CB. it was my first transmitter hunt and i learned 2 lessons: people don't like it when you honk your horn to see if you can hear it through their microphone (but really it was to see if they said 'is that you honking, what a jerk'); and secondly, if the person switches to a handheld transmitter when they think you're getting close, it completely throws you off.
