Ham Radio Life Style
I started with simple single band QRP kit in the 80's, and project after project I made different HF all mode radio home projects, for this result I have to thanks firstly my solder smoker friends and then my strong passion for RF projects allowed me to make even a complete Home made rtx for 50 mhz and 144 mhz SSB band.I also like AM modulation, medium wave and broadcasting low level AM TX until 100 watt power.

Any RF schematic, simple or complex, is for me a source of inspiration for new radio projects even if I have to read many technical books. Many old operators have today a home made rig, but we are a small % group in the Ham Radio panorama, though today with Internet, technical forum, schematic and application notes available on line, building a home made radio is more easy compared to the past, but a good senior teacher always helps.
