I Built a Bi-Directional QRP Wattmeter from Scratch — Stockton Bridge Manhattan Style
In this video I build the Stockton Bi-Directional Wattmeter and SWR Indicator from the G-QRP Club Telford Buildathon 2023 kit, designed by David Stockton GM4ZNX and originally published in SPRAT 61 back in 1989. The Stockton bridge is a deceptively simple circuit using just a BN43-202 binocular ferrite core and a handful of components, built here using Manhattan style construction. A great little project for any QRP station!

Homebrew Radio Roundtable: Stockton Wattmeter + DIY RF Amplifier
In this episode, Tobias KK7BCO and I continue our discussion on the Stockton Bidirectional Wattmeter and SWR Indicator project, covering our progress, build experiences, and what we’ve learned along the way. With Adam K6ARK unavailable this month, Mitch NK3H joins the roundtable and shares details from his RF power amplifier build, including design considerations, challenges, and lessons learned from the project.
If you enjoy QRP, portable operations, electronics, and building your own gear, this episode is for you. We also announce our next scratch-build project, so be sure to follow along as we continue building, experimenting, and learning together over the coming episodes.
This episode wraps up the Stockton Bidirectional Wattmeter / SWR Indicator build and kicks off the next project in our ongoing scratch-build series.

In this episode, we take a roundtable approach as each host brings a topic to the discussion. Brian shares insights from the Rookie Roundup and what makes it a great entry point into contesting. Dan talks about coordinating an ARISS contact, working with educators and local hams to connect students with an astronaut aboard the International Space Station. I wrap things up with a look at a VHF/UHF book I’ve been reading and what I’m taking away from it. If you’re interested in ham radio events, educational outreach, or building your knowledge of VHF and UHF operation, there’s something here for you.

I picked up a free Cheaper Beeper at Ozarkcon 2026. This simple circuit is a fun Morse code practice oscillator made from just five components – plus a power source, speaker, and 3.5mm jack.

He Builds DIY Radios… And Leads a 300+ Member Ham Club (KM4UDX)
In this episode, we sit down with Don Taylor, KM4UDX, to talk through his approach to homebrew radio and hands-on experimentation. From uBITX modifications to scratch-built projects and antenna work, Don shares what he’s building, what’s working, and what he’s learned along the way. We also discuss his role as president of the Vienna Wireless Society and how the club supports operators through activities, mentorship, and getting people on the air. If you’re interested in building, experimenting, or getting more involved in a local ham radio community, there’s a lot to take away from this conversation.
