When I first got it was set off quite often when I was transmitting. There was a notice posted in one of the magazines that if this happened the unit was to be sent back to ACK. I sent mine back to them and they put a ferrite (?) on the telephone type cable that goes to the control unit and some internal changes. The unit has never gone off since except for tests. I did have lots of RF related problems when my plane was new. Mostly caused by the cheap intercom I was using. RF even lit my gear lights. The RV guys don't have RF problems in their planes because the antennae are outside and RF won't go through Al. I still set off my gear warning horn when I transmit sometime. I dismissed Marvs concern about the crushing of fiberfax too quickly, because the 235 only called for 1 layer of fiberfax, and that did not distort the SS. Bill N7WB
