Hi, Indeed, vibration in mobile transport creates triboelectricity, a charge build up by friction of wires insulations against conductors. It could be not the foam of the box, (which usually is grey or black indicating carbon content) but the wiring inside the radio.
It is always good practice to short a cable before connecting it to other electronics to remove any residual charge. 73, Stuart K5KVH _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
