I just revceived an ICOM F4S-A but it didnt come with a charger. I plugged a 12V into it and it said high voltage, but a 6.5 V AC adapter was not enough. What do I need to charge/use the radio? Also, what cable and software do i need to program this, and where does the cable to program it plug into? Do I need a cable to program it, or can I do it manually without one? thanks! -nick
