These new little software based radios are amazing! I'm traveling in the UK now now with a truSDX -- I've run it from all sorts of places with a wire hanging out hotel windows.

I've been an Extra since 1977, and I've never seen a better time to be a radio hobbiest! So many things are possible today. I still run mostly CW, copying in my head, but I enjoy the digital modes when doing "hotel room" operations with makeshift antennas.
