The Lost Art of Understanding Our Radios

A contrast between advanced HF radio manufacturing overseas and U.S. amateur radio operators using finished equipment, symbolizing the gap between radio design knowledge and radio operation.

The Bad Place: Before the Radio Theory was known by Operators

At the dawn of the 20th century, radio was mysterious, fragile, and poorly understood. Communication over distance relied on cables, messengers, and guesswork. Early wireless systems were unstable, interference-prone, and often unreliable.

Radio existed, but understanding our radio would take a while.

This was the bad place: a world that knew radio was powerful, but didn’t yet understand how to control it, refine it, or trust it.


Pride: Mastery Through Hands-On Radio

Following World War I—and through the rise of the British Empire’s global communications network—radio entered a golden age of understanding.

By the early 20th century, radio was no longer confined to governments and industry. It became a technology that individuals could build, modify, repair, and improve—often with parts and knowledge they acquired themselves.

In the United States especially, amateurs were:

  • Winding coils by hand
  • Building transmitters from discrete components
  • Repairing receivers at home or in the field
  • Understanding circuits because they had to

Radios were not sealed products; they were instruments. Accessories, antennas, tuners, and power supplies were designed, shared, and iterated on locally.

This was a time of justified pride:

  • Pride in skill
  • Pride in understanding
  • Pride in independence

Amateur radio wasn’t about owning technology. It was about knowing it.


The Warning: Convenience Replaces Curiosity

As decades passed, radios improved rapidly. Reliability increased. Miniaturization accelerated. Eventually, radios became consumer products.

The warning signs were subtle:

  • Schematics became harder to obtain
  • Repairs shifted from component-level to board replacement
  • Surface-mount parts replaced accessible through-hole designs
  • Firmware replaced circuits

The hobby didn’t collapse—but something quietly changed.

Understanding became optional.

As long as the radio worked, curiosity was no longer required.


The Fall: When Repair Leaves the Community

The fall didn’t happen all at once. It happened when radios stopped being repairable by their owners.

Today, a large percentage of amateur radio operators can no longer work on their own equipment—not because they lack intelligence, but because the ecosystem no longer supports it.

I live in a region dense with technical talent and higher education—multiple colleges, engineering programs, and skilled professionals. Yet when my 1994 Yaesu HF transceiver failed, the prevailing advice wasn’t local troubleshooting or schematic analysis.

It was:
“Send it to a repair shop in Florida.”

A decades-old amateur radio.
Shipped across the country.
Because no one nearby could fix it.

That moment marks the fall.


The Worse Place: Where We Are Now

This is the worse place—and it’s where we are today.

Modern amateur radio is dominated by extraordinary equipment designed by companies like Yaesu, Icom, and Kenwood—companies that hold decades of accumulated HF intellectual property. Understanding our radio or anyone else’s for that matter is pipe-dream.

The radios are brilliant.
The performance is stunning.
The knowledge is sealed away.

Much of the global East now creates and maintains the understanding, while most of the U.S. amateur community just consumes the results.

We buy the radios.
We compare features.
We are satisfied—as long as they work.

But when they don’t, the answer is no longer “Let’s fix it.”
The answer is “Where do we get it fixed?”

Like every other consumer electronic device, we buy another one. This doesn’t feel right.

That is not where amateur radio began—and it is not where it thrives.


Why This Matters to Clubs and the Future

At Johnston Amateur Radio Society, like many clubs across the country, we’re focused on membership growth and engaging new operators.

Younger, technically curious people want more than polished tools. They want to be captured by the technology.

  • To understand how our radios work
  • To trace signals
  • To be able to repair what breaks
  • To customize and build what doesn’t exist

Remember the Erector Set? Radios don’t engage this kind of behavior today. What they do is put a seal on the enclosure and tell you your warranty will be voided if you break it.

If amateur radio becomes only an appliance hobby, it loses the very spark that once made it revolutionary.


My Goal: Reversing the Arc

With my HF SSB radio project, I’m not trying to recreate the entire body of global RF knowledge. That would be unrealistic.

What I am trying to do is interrupt the fall:

  • Bring schematics back into the conversation
  • Treat RF as something understandable, not mystical
  • Talk about models, stability, noise, and tradeoffs
  • Encourage building, not just buying

If we can reclaim even part of this understanding locally, repairability—and pride—returns with it.


Why This Article Uses the “Pride and Fall” Story Model

This article follows the Pride and Fall narrative structure described in Storyteller Tactics by Steve Rawling (Pipdecks):

Bad Place – Radio existed but wasn’t understood

Pride – Mastery through hands-on experimentation (1918–1939)

Warning – Convenience quietly replaces understanding

Fall – Operators lose the ability to repair their own tools

Worse Place – We rely on distant experts and sealed knowledge

This structure matters because it mirrors reality:
Progress without participation doesn’t lead upward—it leads outward, away from us.

Understanding our radios is not nostalgia.
It’s the foundation of resilience.

And amateur radio deserves to stand on it again.

    David,
    When I fell in love with radio back in the early 60’s, I met my first Amateur radio operator. He was just a block away from my house and my dad had given me a set of hand held radios which I fell in love with. My friends and I were so excited being able to talk back and forth several houses from each other. I already was enfatchuated with AM radio and had my own collection made by Hitachi and even a Transoceanic radio from Zenith. Sadly, the would be “Elmer” was not friendly or even helpful to me as excited as I was to see his wall of glowing tubes and to hear the long distance signals coming out of his speaker. He basically said that I needed to get a degree in electronics to understand what he was doing and that I shouldn’t be using my walkie talkies and interfering with his hobby.
    I kinda felt like I was doing something wrong and shouldn’t even use the equipment after that. He also said that I could get into real trouble if I interfered with the taxi cab drivers that also used the bands. It literally took another decade before I started to reestablish my connection to the hobby and once again I was hooked. So what you are doing for the youth and others really means a lot to me. Sharing your time, efforts and talent with a straight forward approach and keeping things understandable and doable. Using today’s tools and a convoluted highway of roadblocks to get your ideas accomplished is not an easy task even for large companies let alone an amateur radio operator with a dream. I know your efforts will be appreciated and if nothing else they will inspire others to keep trying and forge ahead. Thank you 😊
    Best Regards,

      Mike,
      I appreciate the kind words. I’m certainly trying. I got busted by several people on Reddit claiming I had put out “AI slop”. I did post something that was incorrect because I used a range of years from a book about radios in the British empire. The sentence was saying that radios went from governments and industry and into the general population in the early 20th century. I shouldn’t have used the year range from that book. Anyhow, I’m using every tool I can get to make my dream happen.

      Again, my heart is in the right place. I want to spark an interest with young folks where they might get involved in DIY and homebrew within our hobby.
