Second Hand Amateur Radio Gear. The American Radio Relay League (ARRL) Amateur Radio Handbook is published every year and has (nearly) everything you need to know. I encourage all to make a little radio for yourself or build with your kids. Much like shooting, ham radio is expensive. NW Amateur Radio Society - see the TECH TOPICS section for some great homebrew tips. The circuit works through VHF and lower UHF, but it can not easily be calibrated for more than a single ham band. My 40m HF station is a complete Amateur Radio Station from scratch, with a 600W amplifier.
