They run a custom vendor-locked distro named QTS, so they're not really as easy to modify as a normal system, I don't think you can even install programs like that.

It's funny, I was JUST hankering to take my SW out to browse the airwaves, and then I log on to see this post.
I have a Halicrafters S-119, still runs on tubes. Picks up 2-16MHz.
I already spent some time rummaging around for my antenna, but I can't find it and don't have a spool of wire handy, so I'll need to work on that. Last time I had it set up was a couple years and 2 moves ago.
