This is not my personal idea of amateur radio. My QDX is about a fiftieth of the size and very inexpensive as a kit. Even built it is not expensive. As I said, each to their own.
Having said all this I would happily accept one if someone bought me one! Probably very very unlikely!
By the way what does this mean please?
