Ham radio. You can get handheld radios these days for very little money. I'm not sure what ham radio licensing laws are where you are but you do need a license to operate a radio. I suggest this as your Father will be talking to real people. Just a warning though, ham radio is hard work and involves some learning. 2I0JXA
