Radio Myths – “You’ve Got Too Many Radials!”

• • Leave a Comment

There’s been a surge of new antennas hitting the market lately—many of them verticals. And in my opinion, vertical antennas are fantastic, especially for portable operations.

When I head out to a park, I don’t always have a convenient tree available to hang an EFHW. Even when I do, time matters. I don’t want to spend half my activation wrestling with a throw bag, trying to get it over the right branch, and carefully positioning the antenna. EFHWs are excellent—but they take time. That’s why I often turn to verticals.

I’m not alone. Many activators are coming to the same conclusion, which explains the growing number of portable verticals on the market. Along with them comes a popular idea: using “resonant” or “tuned” radials. The logic usually goes something like this—use a certain number of radials for 20 meters, but when you switch to 40 meters, you need to add more.

At first glance, that sounds reasonable. But flip the logic around, and it starts to fall apart. If that were true, then when moving from 40 meters back to 20 meters, you would need to remove radials. And that should raise some red flags.

Rudy Severns, N6LF, addressed this very question in a QEX article (May/June 2009) titled *“How many radials does my vertical really need?”* His conclusion was simple: more radials are better. Period.

Now, there is a point of diminishing returns. As Severns notes, “You gain perhaps another fraction of a dB going to 32 radials, but by the time you reach 64 radials there isn’t much change. The broadcast standard of 120 radials, each 0.4 wavelengths long, is hard to justify for amateur use—especially at today’s copper prices”.

Still, the principle holds: additional radials continue to improve performance, even if the gains become small. Which means that once you’ve laid out radials for a lower band like 40 meters, removing some when switching to a higher band like 20 meters is actually counterproductive.

So don’t buy into the marketing hype. The idea that ground radials need to be “resonant” or “tuned” is largely a myth. And when someone asks how many radials your vertical needs, the simplest answer is still the best: 

More.

Note: This article is discussing ground radials only. Elevated radials, which play a different role in the antenna system, is a different beast all-together. Rudy Severns, N6LF, discusses these differences in another article written for QEX magazine Mar/Apr 2009. To gain a firm understanding of various ground systems and access to all his test data, I recommend all seven of his articles that can be found (for free) at “https://www.antennasbyn6lf.com/“

Make It Work!

Imagine you’re going on an adventure. A little out of state excursion, where nature abounds and state parks are plentiful. You have a couple full days allocated to grabbing your QRP rig, throwing a wire in a tree, and activating POTA parks to your heart’s content.

Sheer radio bliss.

You get to your first park, open your gear cases, and — much to your horror — realize that your wire antennas and ununs/baluns are in a bag you left on the bench at home. Your POTA dreams are over before they started.

Or are they?

This is where the trial and error experimentation aspect of the radio hobby really comes into play.

What I did have at my disposal was about 40 feet of 18 gauge speaker wire and a 4 foot section of 50 ohm coax with PL-259 connectors on each end.

One end of the speaker wire got shoved in the center pin hole of the SO-239 socket, careful to make sure the shielding covered the ground connector on the socket. Then the coax plug went in, holding the speaker wire in place, with the ground connector on the plug making as much contact as I could muster.

The other end of the coax ground ran to a grounded bolt on the car body, and the speaker wire got stretched out to a tree where I folded it back to as close to 33 feet as I could guess… And that reached a whopping 8 feet in the air at its absolute highest point.

The real star of this setup is the Xiegu G-90 transceiver. This radio will tune a vertical. It will tune a dipole. Heck, it’ll even tuna fish!

This setup tuned up to about 1.35:1, and dropped my 20 watts max down to about 16 watts going out the wire.

Voice modes were absolutely not going to happen with this rigging unless anyone was nearby to do some NVIS work, but I didn’t have the time to really invest in that today. The only real option was FT8 — and these situations are exactly what low signal strength digital modes were created for.

The result? 15 contacts in about a 30 minute window. Enough to activate a park!

If I have enough time tomorrow, I’ll hop on the local repeater network and see if anyone wants to try some NVIS phone on 20 meters… Or maybe I’ll see if I can cram enough Morse code refresher to operate CW… Or, better yet, maybe there’s someone in the area that can rustle up a spare 49:1 for me to buy.

The point, though, is that even with far less than ideal circumstances and gear, there’s always a way to enjoy a day playing radio.

Here are a few photos of what I managed to cobble together.

More Watts, Less Gear: Chasing Power Without Losing Portability

• • 1 Comment

To say this has been a difficult solar cycle feels like an understatement. Not that I claim to be an authority—I’m still relatively new to amateur radio. I was licensed in May of 2020, and early on I heard plenty of “Old Timers” talk about how terrible the bands were.

“Just wait,” they’d say. “In a few years, you won’t believe how good it gets.”

Well… here we are.

A few years later, we’ve ridden up through the peak of the cycle and are now heading down the other side. And honestly? I find myself almost looking forward to solar minimum. That probably sounds backwards, but this cycle hasn’t quite lived up to the hype I was sold.

In fact, it’s been frustrating enough that I started looking into amplifiers for my Elecraft KX2. Nothing crazy—just something modest to bump my QRP signal up into the 35–50 watt range during what’s supposed to be the best part of the cycle.

Naturally, I started with Elecraft. If I’m running their radio, it makes sense to see what they offer. That led me to the Elecraft KXPA100 amplifier, which would effectively turn my KX2 into a full 100-watt station. It sounds perfect… until you see the price.

As of April 2026: $1,470.

That stopped me cold. For that kind of money, I could buy two Yaesu FT-891 radios. Which, as of right now, are about $730 each and already deliver 100 watts out of the box. It’s hard to justify spending more on an accessory than on a complete, capable transceiver.

So I kept looking.

However, what I found didn’t get much better. The only reasonably priced option was a kit from QRP Labs—a simple amplifier for about $30 that can push a QRP rig up to 50 watts… but only if you feed it 20 volts. If it is run from a typical 12.8V battery, you’re realistically getting around 25 watts. On top of that, it’s single-band.

Now, I love the price. But if I need multiple units for different bands, plus additional power considerations, the simplicity and portability of a QRP setup start to disappear pretty quickly. For the savings in price, I would need to expand my station to include a separate power supply and multiple amplifiers to cart to the parks.

And that’s where the frustration really set in.

Every amplifier I found that could take the KX2 to 50 watts or more ended up costing as much as—or more than—just buying a 100-watt radio outright. I completely understand paying a premium for a high-power amplifier that pushes well beyond what a typical QRO rig can do. But paying that same premium just to reach QRO levels? That’s a tougher sell.

At some point, you have to ask what problem you’re actually trying to solve.

If the goal is simply more power, then surely the easy answer is to buy something like a Yaesu FT-891 and call it a day. But for me, that’s not really the point. I chose the Elecraft KX2 for its portability, efficiency, and the flexibility it gives me in the field. I don’t want to replace that—I want to build on it.

So the search continues.

Somewhere out there has to be a balance between a portable, reasonably priced amplifier that doesn’t force one to bring an abundance of extra components and cables. Maybe it’s a kit. Maybe it’s something lesser-known. Maybe it’s something I haven’t even considered yet.

Either way, I’m not done looking. Because while the portability of the KX2 is great, there are times when a little extra power makes all the difference—and finding the right way to get there is part of the journey.

5 Things Every OP Should Know

• • Leave a Comment

Even as I typed this title, I remember back to my years as an ISO auditor. There was a saying that rang through my circles, “Don’t ‘should’ on people.” It is obviously a play on words that are not appropriate in all circles, but this speaks to our tendency to make everyone “conform to the way I do it” or the way I think it should be done.

And even in typing this explanation leads to a whole other discussion that may one day grace my blog. But to keep our focus, even as I realize I mustn’t “should” on people, there are just some basic things we all should understand about this hobby. From new to old OPs, let’s jump into this list, and learn what we can.

1. You don’t need expensive gear to have fun!

I remember when I first thought about getting my license in amateur radio. I had so many questions that I struggled to get answered. But one thing that I was told was that I could spend $15 to $15,000 in this hobby.

When I first got my license, the Baofeng UV-5R was only 15 bucks. This cheap handie-talkie was an easy and simple way to get on the air. For me, I was interested in CW from the very start of my journey and so a purchase of a simple 20m QMX mini (for about $50 as a kit) to start making HF contacts was an easy decision.

This meant that for under $100 I had 2 radios covering VHF/UHF and 20m HF, that could reach just about everyone in the world, if propagation would allow. I had a blast with that QCX mini, and although I have purchased much more robust radios since then, I still use that QCX today.

And as technology continues to develop, one can now purchase a QMX multi-band multi-mode transceiver (that does CW, Digital and SSB) for just a bit over $100! Which knowing this makes me think… I might need a new radio!

2. Clubs and Mentors are INCREDIBLY Valuable

Amateur radio is the one hobby that have a special name for their mentors. Elmers are so valuable to your journey, and to have a good one is greatly coveted. Don’t skip this part. Sure, YouTube is your friend, absolutely there is a lot of info on the internet, but there is no comparison to being able to sit down with a good Elmer and ask specific questions.

And although this journey that you are on has a lot of individual opportunities, to have a club, a group of like minded individuals to have your back is priceless. If you ever had a bad experience with a club, or don’t grasp the value, please read my post below. Too many people underestimate the value of a good Elmer and Clubs, and the hobby suffers for it.

3. Listening is an Important Skill

This is probably the most important thing in my list! I could literally write a thousand word essay on this point alone! So many situations I have been in that listening either got the person a contact, or the lack of listening caused them to miss a contact.

Now I understand that not everyone is chasing rare DX, or even POTA entities. I know Hams that are only after a good rag chew. But even those “rag chewers” need to develop the skill of listening. As someone who runs a lot of QRP, I have had multiple people just move on to my frequency and start calling CQ. And I understand they may not have been able to hear me… but they never even asked if the frequency was in use. 

So do the hobby a favor and learn to listen. Listen before calling CQ, Listen before answering a CQ. Listen before assuming the station calling CQ is answering you. In other words, just listen! It is a very important skill.

4. Portable Operation Changes Everything

I know it is a lot of fun chasing DX in the comfort of your home with a KW station pumping through your 7 element beam. I also understand that to resort to a simple 100w (or less) and a wire, seems like stepping backwards at first—like trading horsepower for humility.

But give it time, and you’ll realize it’s not a downgrade at all. It’s a different kind of challenge. One that sharpens your ears, refines your patience, and reminds you that this hobby was never just about power—it’s about skill, creativity, and the thrill of making something small go a very long way.

And for those who think that in order to experience portable operation you must join in with POTA or SOTA or some other program… Remember that Summer and Winter Field Days are also possible portable activities, and can also be supplemented with a good Elmer or Club (refer back to #2 on this list).

5. This Hobby is Bigger Than You Think

I know of no one who has plumbed the depths of this hobby. The longer you’re in it, the more you realize you’re only scratching the surface. Just when you think you’ve “figured it out,” you discover another corner—another mode, another band, another challenge—that pulls you in.

Maybe you started with a handheld and a local repeater. Then it was HF. Then digital modes. Then portable ops, POTA activations, contesting, satellites, building antennas, chasing DX, emergency communications, or tinkering with homebrew gear. Each layer opens up a dozen more paths you could take.

And the truth is—you don’t have to do it all.

That’s part of what makes this hobby so great. You can go as deep or as wide as you want. You can be the guy with a modest setup making contacts from a park bench, or the operator with a full station chasing rare entities across the globe. You can build, operate, experiment, serve, or just enjoy the conversations.

But here’s the takeaway: don’t box yourself in too early.

If you’re new, give yourself permission to explore. Try something that feels out of your comfort zone. If you’ve been around a while, maybe it’s time to revisit that area you’ve always been curious about but never pursued. There’s always more to learn, more to build, more to experience.

This hobby isn’t a straight line—it’s a wide open landscape.

And no matter how far you’ve come, there’s always another horizon waiting.

———

So there is my list of 5 things every OP should know. What do you think? Did I miss one, or two? Is there something you think should be on this list. Leave a comment and let me know! And finally, Stay curious, keep experimenting, and enjoy the journey.

Club Build Event and VE Testing

• • Leave a Comment

[Note: updated from original with corrected mailing address and additional information]

We will also be conducting testing at the build event location starting at noon.
Please contact any club member to let them know you’re interested!

Calling All Hams,

You are invited to build the Pacific Antenna Micro Attenuator kit at the Defiance County Amateur Radio Club project day.

Fox Hunts will be coming up and having an antenna attenuator is a must have.  This attenuator provides up to 40dB in 4 steps of 10dB.  If you have never soldered, this is a great first time kit to learn how.  If you’re an old hand at it, it’s still a fun build.

With the kit the DCARC is providing a 3D printed base that can also be used to mount it to an antenna.  If you already have an antenna and handheld 2M radio, bring them.  If not, we will have some available for you to test the operation of the attenuator after construction with a couple of live fox hunt transmitters placed some distance away.

The construction project will take place on April 11th at 2 PM.  Location:

Ney Church of God
03413 OH-15
Ney, OH 43549

The cost to participate is $30 with a deposit of $15 due by March 21st. For the deposit, please make out a check to the Defiance County Amateur Radio Club and mail it to:

Defiance Amateur Radio Club
925 S Clinton St  #21
Defiance  OH  43512

Or drop off cash or check at the next DCARC meeting on March 9th. The balance is due, cash or check, the day of the event.

Lastly, building kits works up an appetite.  After all, the DCARC is the ‘Crock Pot’ club.  So if you would like to bring a dish to pass that would be great. Let me know in the email.

Hope to see you there,

73 John KD8JSP
