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.

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.
