On HF I only operate QRP except when operating a contesting station provided by someone else.
At home my setup is simple but not optimal due to our relatively small city lot. My rig is an Elecraft K2 I put together about 10 years ago (great fun!), antenna is a relatively random length long wire in a suboptimal installation, and a tuner. It doesn't work great but works well enough in some bands and I've had CW and SSB contacts on 5W into Europe, South Pacific, Australia, and plenty from Japan, not to mention most regions of North America and to the south. I do OK on 40M for local communications. The K2 is fun to use.
I've done a little portable QRP while camping and love being able to string up a 20M dipole properly.
Once I build my deck out back I'm going to put up a tower mostly for UHF, maybe some high speed GHz data, and perhaps finally I can get a better inverted V going. That would get me on CW more.
PS: We live atop one of the higher hills in the city. I'm open to thoughts on putting up a vertical antenna given my space challenges at present; any other space challenged hams doing (relatively) well with one?
