[ICOM] IC 2730A

[Larry Hinton]

That is a very bad way to connect a radio. Power spikes from the starter can render a radio useless. You are better off connecting the radio directly to the battery and using the power ON/OFF switch on the radio once the vehicle is started. The battery provides a little filtration when you are directly connected to it but will not completely filter all the spikes.

On radio's of the past, there  was an ignition sense wire but no ext connections I see on this rig.  Is there a way to insure it powers on each time I crank my truck?? Hal/WB4AEG
