Re: [Elecraft] I've been thinking!

Having ran a couple of true SDR's I decided that I did not like one for a radio that I had to use all the time. They fell short on receivers for one thing and were tied to a computer for another. The computer caused another set of problems itself and the fact no power no radio. The last one I used
