In this Homebrew Workbench Roundtable, Adam K6ARK, Tobias KK7BCO, and I dig into QRP antenna tuners and workbench projects. We cover L-match and T-match concepts, Adam's K6ARK QRP Antenna Matching Unit, and the G0FUW HB-ATU based on the classic Heathkit HFT-9 circuit. Tobias built two scratch versions plus a kit. I just got my parts together.

On the antenna side, Tobias is working on a trapped vertical for 15, 17, and 20 meters, I added 60 meter legs to my linked dipole, and Adam built an aftermarket battery bank for the Yaesu FT-3DR and some tiny QRP bandpass filters.

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.
