I got my novice class license in 1982 at the age of 13, and upgraded to general class in 1984. My favourite mode is cw because of the modest equipment requirements, having never had more than 100w and random wires or dipoles. I was active up to about 1992, when I went QRT because of my studies. Between 1992 and 2011 I worked probably about 20 QSOs in total. I never left the hobby though, it was just centered on radio theory, not on the bands.

For the past 30 years I have spent on average at least a few hours per week reading about RF. I built an Elecraft K2 in 2002, when I also started collecting proper RF tools. My pride and joy is now a small RF testbench with some high-end (although slightly dated) equipment, amongst others a Rohde&Schwartz spectrum analyzer, a signal generator, a R&S radiocommunications analyser and a DG8SAQ vector analyzer. The more sophisticated my equipment, the less complicated are the things I build, at present I am just testing different simple amplifier circuits for s-parameters, IMD performance and noise figure, all of which I can now finally measure. I am motivated by, and greatly respect the great RF gurus like Wes Hayward and Ulrich Rohde, and the many hams who pioneer technology for us in QEX. My ultimate receiver is the R&S spectrum analyzer as a front end, with a QS1R SDR connected to its IF output. It goes from 9kHz to 3,5GHz with an astounding dynamic range and all modes.

Last year my very close friend Ari OH5VA built me a 24m telescoping tower, on top of it is an Optibeam for 20-15m. I am located on the side of a hill (nearly on the top) with a great unobtructed path to Asia. The beam has opened up the hobby in a completely different way. Having previously only had access to wire antennas, the difference is staggering.

I work as a family doctor or general practitioner, work takes up lots of my time, so I dont get to spend all that much time on the bands, but when I do, I enjoy the ham spirit that I have known since my early teens. Coming back on band feels like I was never gone. Give a shout (or the equivalent in cw) if you hear me!
