I’m having the hardest time trying to figure out why I can’t program my F-4011 radios. I have the Icom OPC-478UC cable and software.
I am using the COM channel tied to the cable. what ever combination i use in connection order gets the same result. It always says cannot access COM. the cable is connected and the unit is on. the plug is inserted as far as it will go.
do i have a bad cable? what am i doing wrong?
I’m really getting frustrated at this point. I’ve 50 of these i need to program.
