I have correct cable, the one that doesn't req. the special USB driver you have to d/l. I hook it up, got the correct port #, the display is flashing and the thing will not update. It says it can't communicate with the radio. I even held my foot up in the air to see if that would work. Anyone has any ideas? Icom support says I could send it in, that will cost me around 90 something bucks an hour.
