This is an interesting topic. Most replies say that they never even thought of letting their Amateur license go. Some, let it go, but got back in later. I have had mine since the early 70's. At first, I wanted to talk on the local 2 meter repeater, but that wore off pretty quickly. Then, got interested in 2 meter sideband, but lacked the funds to build a station that could compete. Lost interest in ham radio, but worked in the electronics/telecommunications fields. For probably the last 20 years, the only band I have been interested in is 900 MHz. I have done a bit of experimentation there, and enjoyed most of it. I don't really care about talking anymore, and keep the license just to be able to legally transmit on my favorite band. I am getting on in years, so probably one more renewal will be it for me. Amateur radio is an interesting hobby. There is something there for almost anyone. You don't have to be interested in HF, or DXing. There are a lot of very specific fields of interest one can pursue. I have found microwave and weak signal to be fascinating, but never had the time to devote to them. Kind of wish I had.
