In this episode of Guy & Gus Ham Radio Gizmos, we explore the RIGHT way to use dummy loads after Gus learns the hard way. Plus: Norwegian WWII resistance radio operators, Aerial's Q&A on power handling, and Guy's "This Week in Ham Radio History."============================ I have received a number of emails asking about what they can do to support the podcast.And I don't believe in asking for donations so I decided the best thing to do is to let Guy and Gus do this for me. I am continue to expand the line of products and use Guy and Gus to help.Customize with YOUR Name & Callsignhttps://Store.HamRadioGizmos.com============================What You'll Learn:Dummy load power ratings and why they matterSWR basics and proper impedance matchingOil-filled vs resistor-type dummy loadsHow to safely test transmitters and amplifiersAmazing WWII ham radio resistance story

Gus spent $175 on a vintage Fender Deluxe Reverb transformer to repair his Heathkit Warrior. There was just one problem: it's a guitar amp transformer. Guy tries to explain why impedance ratios matter. Gus tests it anyway. Even Mr. Whiskers knows this is bad.Meanwhile, Guy reveals the surprising origin of Q-signals (spoiler: British ships and railroad operators invented them, not hams), and Aerial attempts humor while answering listener questions about first HF antennas, tuners, and apartment operating.

⚠️ DISCLAIMER:If you order vintage audio transformers on eBay, attempt to use guitar amp parts in ham radios, or test questionable equipment at your brother's house, this program may cause spontaneous understanding of why specifications actually matter. We are not responsible for terrified cats, strongly worded feedback from spouses, or neighborhood power outages. Don't try Gus's methods at home.HISTORY OF Q-SIGNALS https://youtu.be/PTDhrAvVhFUWelcome to Ham Radio Gizmos, where you Laugh and Learn—because twin brothers Guy and Gus can't agree on anything about amateur radio, and you'll learn everything while they argue about it.⚡ IN THIS EPISODE:🔧 The Transformer Disaster:Gus explains why a 1967 Fender guitar amp transformer is "basically the same" as an AM modulation transformer (it's not). Guy explains impedance matching. Gus tests it at Guy's house. The results are... distinctive.📻 The Real History of Q-Signals:Guy reveals that hams didn't invent QSL, QTH, QRM, or QRP. British merchant ships did in 1909. Then railroad telegraph operators influenced them. Then we borrowed them. Indefinitely.🤖 Aerial's Q&A Debut:Our AI assistant answers real listener questions:Mike in Sacramento: Best first HF antenna for new Generals?Sarah in Portland: Resonant antennas vs. tuners—what's the difference?Tom in Atlanta: Should you buy an expensive radio or invest in your antenna?Jason in Chicago: Realistic apartment HF solutions that actually workPlus, Aerial attempts her first jokes. Guy encourages her. Gus provides commentary.

This week on Guy & Gus Ham Radio Gizmos: Gus's homebrew radio combiner takes down the entire neighborhood's power, we uncover the secret WWII ham radio operators who intercepted Nazi communications, and our AI assistant shocks Gus by matching his vintage radio expertise!In Episode 2, we explore the incredible story of the Voluntary Interceptors—over 1,500 amateur radio operators (many just teenagers) who secretly helped win World War II by listening to Nazi transmissions from their garden sheds. Most didn't learn what they were REALLY doing until 30 years later!Plus, Gus attempts to build a $15,000 radio combiner for $50 using salvaged TV parts. What could go wrong? (Hint: The power company got involved.)And in our Ask Aerial segment, Gus tests our AI assistant with a technical question about selenium rectifier replacement in vintage Hallicrafters receivers—and gets an answer that leaves him speechless.

Everyone's talking about how AI is going to ruin jobs, kill creativity, and replace everything we love. But here’s the thing—they said the same about the printing press, railroads, electricity… even ham radio. In this video, we take a ride through history’s greatest tech freakouts—and uncover what they all missed. Whether you're a ham, a skeptic, or just tech-curious, this one might change your frequency.Reference Sources1.

During World War II, radios were confiscated from civilians across Britain. Yet somehow… a few were quietly given back.Why? Because hidden in the static were signals the military couldn’t afford to miss—coded transmissions from the German intelligence services.While Enigma was being cracked at Bletchley Park, another ultra-secret operation was underway. A ghost army of ordinary hams, teenagers, and even a few women sat in their bedrooms and garden sheds, pulling faint Morse code out of the ether. They logged everything. They asked no questions. And for decades, they told no one.The truth only began to surface in the last 40 years. Until then, even their families had no idea.Who were these “secret listeners”?Why did the government trust amateurs with a task so critical to the war?And how close did they come to being forgotten entirely?This is the hidden story behind ham radio’s most secret chapter.To learn more check out The Secret Listeners by Sinclair McKayhttps://amzn.to/4mt5BwRResources & References used to write this story.BBC News – “The teenage radio enthusiasts who helped win World War II”Katia Moskvitch, BBC Technology Reporter (2013).👉 https://www.bbc.com/news/technology-23162846RSGB RadCom – Voluntary Interceptors Tribute (September 2018)Article adapted by John Swartz, WA9AQN.👉 https://rsgb.org/main/blog/news/gb2rs/headlines/2018/09/07/voluntary-interceptors-tribute/BBC Documentary – “The Secret Listeners” (1979)First public reveal of the Voluntary Interceptors after decades of secrecy.

In this episode, we crack open the dusty files of radio history and dive into the long, complicated, and sometimes quirky relationship between the Federal Communications Commission (FCC) and the ham radio community.

From terrifying exam rooms with stone-faced government testers, to modern RDF vans chasing down rogue signals, it’s been a wild ride since 1934.

I’ll share my own firsthand memories of getting licensed back when the code test wasn’t optional—and intimidation was part of the deal. We’ll explore how the FCC tracks down interference (yes, with spy-van-looking trucks), the strange mystery of number stations, and how policy changes like dropping the Morse code requirement have shaped the hobby for new generations.

If you've ever wondered what the FCC actually does for hams—or how close they might be to your QTH when someone fires up a jammer—this one’s for you.

So grab your headphones and settle in. You might just come away with a new appreciation for the folks who issue us our license... and keep us honest.
