I've bought a couple of two way radios, and when I read the owners manual for them it said I needed a radio license from the FCC before using the radio. Anyone have any idea how much this will cost? Is it a one-time payment, or does it have to be redone every year? The radios are motorola "Talkabout" that operate at 1 watt. I looked around the FCC web site but I think I have to register with them before they tell me how much I owe for a license. Anyone have any input?
