I started with simple single band QRP kit in the 80's, and project after project I made different HF all mode radio home project. Ffor 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.
