Hi -
I am a HAM radio operator and have a 2M (144MHz) / 440 MHz radio in my car.
I have not tried 440, but on 2M a transmission sometimes triggers the unit as if I had pressed the call button.
The phone goes into "Please say a command" state.
I put a clip on ferrite sleeve on the cable bundle into the unit, but that didn't seem to help.
Any ideas?
