I have e-mailed ICOM support to get the real scoop. Probably they are off today. If I dont get a reply back soon I'll call them. At any rate I will post my findings. Someone had a good point about the loading. The rating could be a resitive and not inductive as a relay coil might be in an amplifier. If anyone has contacted ICOM for the real scoop....speak! :-) John N1JM
