Part 3 of the Chuck Adams W1AW Direct Conversion Receiver build — and it’s receiving. I tuned the receiver using both a 14.0480 and a 14.0475 MHz crystal, and both worked well. With the radio on, I pulled in W1AW live out of Connecticut. The signal drifts in and out, but that’s band conditions — closer stations come in noticeably stronger. Three stages, three shorts, one working receiver.

In Part 2 of my W1AW Direct Conversion Receiver build, I tackle the audio stage using the LM386 IC. Once the circuit was complete, I connected a speaker and touched an open pad at R7 — and the static jumped dramatically, confirming the audio stage is alive and amplifying. The Chuck Adams W1AW receiver is coming together one stage at a time.

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!

In this episode, I sit down with Rick N3FJZ — a prolific homebrew builder known in the SolderSmoke community for his meticulous construction, clean schematics, and commitment to all-discrete analog design. We trace his journey from his first scratch build projects to his current tranciever with a custom front panel digital display.

Join us as we explore how you can get involved in portable radio, QRP, and more in this episode of the All Portable Discussion Zone (AP/DZ). Every aspect of portable operations is covered in this biweekly podcast, from news and gear to achievements, the workbench, contests, awards, and beyond.

Tried tuning the W1AW 20m Direct Conversion Receiver local oscillator with an oscilloscope and got strange readings — so I grabbed my Yaesu FTdx10 instead. Tuned to 14.047MHz, listened for the carrier, and adjusted trimmer C1 until I had a nice ~600Hz beat note. Sometimes your HF rig is better test equipment than your test equipment! Part of my W1AW Direct Conversion Receiver build series.

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.
