50 Years Licensed and Still Building — Gary W0MNA & Martha W0ERI

Gary W0MNA and Martha W0ERI have been licensed for over 50 years each and are still building, activating, and teaching others to do the same. Based in Leavenworth, Kansas, they are regulars at Four Days in May and Ozark Con, where they mentor the Friday evening build session and beta test new kit designs for the Four State QRP Group.In this episode we talk about how they each got into ham radio, their decades of kit building and homebrew projects, their SOTA activations as a team, and the very active club they run in Leavenworth where monthly build sessions, outdoor operating events, and ARES work keep a growing membership engaged year round.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.**SolderSmoke DISCORD INVITE**: https://discord.gg/GYVRZSBVFCConnect with us:* Discord: https://discord.gg/WVE3vVveWU* YouTube: https://www.youtube.com/c/redsummitrf* TikTok: @redsummitrf* X (formerly Twitter): @NJ7V_Support the channel:* Buy us a Coke: https://www.buymeacoffee.com/RedSummitRF* Red Summit RF Amazon Storefront: https://www.amazon.com/shop/redsummitrf#apdz #HamRadio #QRP #Workbench #Electronics #homebrewradio #amateurradio #hamradiopodcast #SOTA #POTA #PortableOps #kitbuilding #ARES #FourDaysinMay #OzarkCon #elmering #hamradioclub

Homebrew Transceivers Designed for the Trail — Paul VK3HN

Paul VK3HN has been building homebrew radio gear since the late 1970s and activating SOTA summits in the Australian bush since around 2015 — and he'll tell you the two pursuits feed off each other perfectly. His Summit Prowler series of homebrew superhet transceivers were designed specifically for backpacking and activating, with every design decision driven by the constraints of the trail.In this episode Paul walks through his journey from a scratch built 2 meter FM receiver as a teenager to a series of increasingly refined portable CW and SSB transceivers, shares how his 20 year career as a software engineer made the jump to Arduino and Si5351 easier than most, and talks about choosing to stay a builder rather than become a full time YouTuber.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).

Homebrew Radio from 1950s Crystals to Satellite - Stuart M0SGV

Stuart M0SGV started soldering at age 8 in the 1950s, building crystal sets with a copper tip heated over a gas cooker. Nearly 70 years later he is still at the bench, building tube transmitters from 1949 magazine circuits, Hans Summers QMX and QDX rigs, a Michigan Mighty Mite, and a high voltage power supply built from scratch to power all of it.In this episode Stuart walks us through a dozen homebrew projects, shares his philosophy on project selection, and offers hard won advice on soldering and why leaded solder is non-negotiable. We also talk about his connections to the Michigan QRP Club and G QRP Club, and his next big project: a QO-100 geostationary satellite transceiver.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).
