I own an Icom IC-746 and it seems to me the 6 prong power cord made by Icom is the worse power cord ever. One problem is only two prongs are used. The other four have no connectors. I have to purchase a new one about twice a year but they are always intermittent. I believe the high current deforms the plastic casing which makes the device intermittent. The metal to metal clips don't touch correctly and there is nothing to make them do so. Does anyone know a way to make the Icom power cords more usable?
