I decided that when I got my license and set up my own station I would try to work on the audio to get the best quality that I could. It took me a long time to be able to afford/assemble the components needed but finally I am happy with my audio quality.
For a description of my audio chain, see this page.
For whatever reason, I have always found Icom HF radios to suit me more than any of the alternatives (that I can afford). Oddly enough I seem to get along better with Yaesu VHF/UHF hand-held and mobile.

For a brief overview of the HF antenna see this page.
For a description of some of the signal monitoring tools I use, see here.
I also have an Elecraft KX3 which I use for portable, and some digital work, see here.
When we moved to the USA, after getting settled it, I dropped in on a local exam session to see if I could get a US license. I took the tech test and passed that with no problem, so asked if I could try others. They said I could keep taking them as long as I continued to pass. I passed General, Advanced and Extra. Of course, at that time, they were of little use without the CW test to go with them. So I setteled for my tech license: KC7FWB.
When the CW requirement was dropped, I re-took the Extra test, and my licensse was upgraded to match. I kept an eye open for a vanity call sign, and when I saw K7UF become available jumped on that.
