He Designs Free QRP Rigs Anyone Can Build — Barb WB2CBA Interview

Barb WB2CBA is a civil engineer by trade and an open source QRP designer by passion. Every circuit he's created has gone straight to GitHub with no paywalls and no kits he controls exclusively, and builders around the world have taken notice. In this episode Barb walks us through his major designs from the uSDX collaboration to the Pebble HF, talks about his experience at Four Days in May, and shares what it feels like to see strangers around the world building circuits he designed and released for free. If you're into QRP, digital modes, or homebrew radio, this one is worth your time.
