CW – A Workout for Your Brain

For those of us who use it, the advantages of the CW mode are well known. It’s efficient and cuts through noise better than voice. CW is also well-suited for low-power (QRP) communications, enabling the use of modest equipment and power sources. Another important advantage is that learning and using Morse code is good for your brain.

It should come as no surprise that ham radio demographics skew heavily towards older adults. Folks over the age of 55 make up roughly 60% to 70% of the ham radio community.¹ It’s also widely known that cognitive decline often comes with age. I’ve always believed that Morse code is good exercise for your brain. In doing some research, I found that scientists have studied this, and there’s solid scientific evidence supporting my beliefs.

Five Ways Your Brain Benefits From Morse Code

Mental Exercise There are several studies out there that show the benefits of learning and using a new skill, such as a new language or playing a musical instrument. With Morse code, you are essentially learning and using a new language, since you are translating sound patterns into letters and words. This type of activity strengthens memory and attention.²

Promotes Neuroplasticity. There are studies that show measurable changes in CW operators’ brains related to listening and motor control. Activities like this have been shown to promote neuroplasticity, or the ability to adapt and create new pathways in the brain.³ ⁴ I’m no neuro-scientist, but I’m told this is a good thing for your brain.

Improved Auditory Processing. Copying Morse code by ear is all about recognizing patterns, rhythms, and differences in pitch. This can sharpen auditory discrimination and focus. It seems to me that recognizing patterns, rhythms, and pitches is pretty similar to playing a musical instrument.

Focus and Mindfulness. Copying CW requires our complete attention and sustained concentration. This exercises your brain, not unlike playing a challenging game or solving a puzzle.

Social Interaction. When you use Morse code to communicate with others, it keeps you socially engaged, which is increasingly important as we age. Social engagement is not limited to just Morse code; hams communicate with each other using a variety of modes. Belonging to a radio club or participating in nets also provides social interaction. During my 50-plus years in ham radio, I have had the pleasure of developing countless friendships, both on the air and in person.

It’s Never Too Late to Start

When I was an 18-year-old sailor training to become a U.S. Navy radio operator, I soaked up Morse code like a sponge. Studies show there’s a good reason for that. Younger brains work faster, while processing speed and working memory can decline with age. That doesn’t mean we older folks should throw in the towel on learning new skills. Au contraire! Remember that neuroplasticity I mentioned earlier? Well, science shows that the ability to form new pathways and connections in the brain continues well into our twilight years.⁵ Contrary to the old adage, it seems you can teach an old dog new tricks.

While younger brains have their speed advantage, older adults approach learning armed with a lifetime of experiences. Because of these accumulated experiences, older folks are often better at problem solving and pattern recognition. Also, our retention and conceptual understanding are often better. We just might need more repetition and smaller chunks of information while learning something new.

Take Your Brain to the Gym

If you don’t already use CW, consider giving it a shot. It can be challenging, but it’s certainly worth the effort. Just be patient and stick with it. I think you’ll find it’s a fun way to communicate.

If you’re already a CW aficionado, grab that key and join me on the air for a workout!

TUMD Stainless Steel Paddles

I mentioned in a previous posting that I have a fascination (obsession) with unusual CW paddles. These paddles are the last in a series of recent purchases (but I doubt it).

These rather industrial-looking paddles are not new; they have been around for a while. They are often sold under various brand names or no name at all. The eBay listing I purchased mine from didn’t specify a particular brand, but they came branded as “TUMD.” The paddles I ordered were shipped from China and took about a month to arrive.

I’m not providing a specific link, since these things are available all over the place. Just search on “stainless steel paddles” and you’re sure to find them.

The Tumd paddles attached to my clipboard. The three magnets are super strong.

Here’s what was included in the box:

The paddles, of course
A stereo cable with 3.5mm connectors
A two-piece plastic case large enough to hold the paddles and cable
Two Allen wrenches
A small adhesive metal disc for applying to the surface of your choice

The accessories I received with my Tumd stainless steel paddles.

The first thing that struck me was that these paddles are built like a tank. The base has three powerful magnets, which I like. At the rear of the paddles next to the 3.5mm jack, is a small slide switch for reversing the “dit” and “dah” paddles. They look great, but my purchase was not without a couple of minor issues right off the bat.

Based on the picture in the eBay listing, I ordered a version of the paddles with smaller, square paddles. What I received, however, was a version with larger paddles reminiscent of the fins on a 1959 Cadillac. Instead of going through the hassle of returning them to China, I opted to keep them.

The next issue was adjusting the paddle spacing. As received, the paddles had different spacing. The paddles each have a hex bolt within a larger locknut of some sort. There were no instructions provided, and neither of the included Allen wrenches fit. Fortunately, Charlie NJ7V over at the Red Summit RF YouTube channel provided all the answers I needed. He has a video detailing how to adjust them and what size wrenches you need. I had the tools I needed in my toolbox, so I had the paddles adjusted to my liking in short order.

I’ve used these paddles on quite a few outings and have grown to like them a lot. Here are some pros and cons from my viewpoint—your mileage may vary:

Pros:

The three magnets on the bottom are seriously strong. They hold tight to the steel strips on my clipboard. I love that!
Once adjusted, they have a great feel and key reliably. They do, however, require a slightly heavier touch. That’s a matter of personal preference, so others may disagree.

Cons:

Weighing in at 3.8 ounces (106 grams), they are heavier than other paddles I use in the field. This is a minor issue or no issue at all, depending on how you operate.
You need two tools to adjust the paddle spacing. From what I’ve seen online, some sellers include both wrenches; mine did not. Again, this is also a minor issue, since the paddle adjustments hold very well and shouldn’t need further adjusting in the field.

Lately, these paddles have been my first choice for portable operation. For $50 (US) or less, they are a pretty decent value.

Playing with Paddles in the Park

I headed down to Ridley Creek State Park (US-1414, KFF-1414) this morning for a pre-Thanksgiving POTA/WWFF activation. While I was there, I wanted to field test a couple of paddles, one new ‌and one I slightly modified.

I mentioned in a previous post (or two) that I somehow damaged the paddles that came with my Elecraft KH1. In searching for an alternative, I came across the KH1 Pressure Paddles from K6ARK. The kits were selling for a mere $22 on Amazon, so I fired off an order.

I’m not as good at building kits with small parts as I used to be. My close-up vision hasn’t gotten any better with age. However, with the aid of my lighted magnifying glass, I assembled the kit in less than 30 minutes with no major issues. The only issue I ran into was the 3-D printed cover didn’t fit against the KH1 too well and needed a little sanding. Once I took care of that, the paddles worked great. Using pressure-sensitive paddles feels a little different at first, but I quickly adapted.

The other thing I did was glue two more magnets onto the bottom of my CWMouse paddles. The four I glued on initially weren’t quite enough to keep the paddles from moving when attached to my clipboard. Two additional magnets seemed to do the trick.

More magnets on my CWMouse paddles — The magnets on my CWMouse paddles. I recently added the two towards the middle.

When I rolled into my usual spot in the park, the place was deserted. I wasn’t too surprised, since it was a weekday and drizzling to boot. My original plan was to operate the KH1 handheld to give the K6ARK paddles a good workout. Given the lousy weather, I abandoned that plan and set up in the truck. I used my trusty 12-foot loaded vertical on the back of the truck.

KH1with the K6ARK Pressure Paddles attached

I started off trying to use the K6ARK paddles with the KH1 on the center console. After two contacts, I decided that wasn’t the most comfortable way to operate. The pressure paddles worked fine, though. I switched over to the CWMouse paddles attached to my clipboard, and the magnets held nicely. It helps that the CWMouse paddles have a light touch, so I’m not slamming them side to side.

On the air, the bands were as mediocre as the weather this morning. According to my band conditions app, we were experiencing an unsettled geomagnetic field. Starting out on 40M, it took longer than usual to make my first ten contacts. After I had 15 in the log, I switched to 20M and picked up a few more. I spent the rest of my time on 17M and 15M. As predicted, the band conditions up there were fair at best. I worked two domestic stations on 17M, and stations in Germany and Texas on 15M.

My loaded whip at Ridley Creek State Park (US-1414, KFF-1414)

I was getting ready to call it quits, but I wanted to adjust the KH1’s real-time clock before shutting down. It had gained a minute or two over the past couple of months, so it just needed a tweak. As I navigated through the menus to set the clock, I heard a very loud IK1LBL calling me. I quickly exited out of the menu and completed the contact. After that, I set the KH1’s clock and packed everything up.

As activations go, this one was nothing special. However, my new KH1 paddles and my modified CWMouse paddles were a rousing success.

And finally, I’ll leave you to ponder this curious AI-generated image of a turkey operating a radio. It appears the turkey might be keying with his left foot (QLF?).

Happy Thanksgiving to you and yours.

Fun Morning at US-1351/KFF-1351

It’s been a busy week here, with a major ARES-RACES exercise, medical appointments, and some unexpected repairs on my truck. With all that behind me, I was more than ready for a QRP-portable outing.

When I drove up to Evansburg State Park (US-1351, KFF-1351) early this morning, the weather was dreary, and everything was wet from the rain we had overnight. I did a quick check of the band conditions app on my phone, which showed only fair conditions on the higher bands. Conditions can sometimes change minute to minute, so I don’t let those band predictions deter me from getting on the air.

I installed my trusty 12-foot loaded whip on the back of the truck and set up my Elecraft KH1 on the center console in the cab. I also used my CWMouse paddles, which are among my favorite paddles these days.

My Elecraft KH1 and CWMouse paddles in use at Evansburg State Park (US-1351, KFF-1351)

As I was setting up my antenna, a woman with a group of hikers yelled over to me, “What are you going to do with that big antenna?”. I gave her my 30 second explanation of ham radio and Parks on the Air. She told me to have fun and continued on her way. Normally, I just get curious stares, but now and then someone will ask about what I’m doing.

The 40M band was really hot this morning. I made my first 10 contacts in about eight minutes. I logged 24 contacts before the activity thinned out.

Like my last activation, I wanted to focus my attention on 20M through 15M. The 20M band was a little disappointing for me today, producing only two contacts. I spent the rest of my time on 17M and 15M. Even with the “fair” band conditions, these two bands did not disappoint. My 4.5 watts was getting some strong European hits on the Reverse Beacon Network.

Today’s DX contacts included:

17M: Italy (2), Slovak Republic, Finland, Germany (2)
15M: Spain, Czech Republic, Germany, Italy (2), Switzerland, France, Denmark, Poland (2)

The action wasn’t exactly fast and furious on 17M and 15M, but I definitely had fun working the DX stations. Many of them were hunters in the World-Wide Flora & Fauna (WWFF) parks program, who sent the traditional WWFF greeting, “44.”

I shut down after an hour and 50 minutes, which is a little longer than my usual activations. In the end, I had 56 contacts in my log, including two park-to-park contacts.

After more than 50 years in ham radio, I still find it amazing that a little radio running less than 5 watts can be heard thousands of miles away. I think that’s what has kept me interested in QRP all these years.

Unsettled Conditions at Evansburg State Park

I had some spare time this morning, so I made a trip to Evansburg State Park (US-1351, KFF-1351) for some radio time. Before I left, I took a quick peek at the band conditions and saw that we had some unsettled geomagnetic conditions. Despite the less-than-optimal conditions, I had a pretty good morning.

When I rolled into the parking lot, I was the only one there. That’s not too surprising for early in the day on a Wednesday, I suppose. I kept things simple and operated from the truck with my Penntek TR-35 (5 watts, CW) and a 12-foot base loaded whip. I was also using a set of paddles I purchased recently. (More about those in a future post.)

The new paddles I was trying out. I do a separate post on them soon. — The new paddles I was trying out. They’ll be the subject of a future post.

As is my usual practice, I started out on 40M. As I was tuning across the band, I heard N1BS in Rhode Island and had a quick park-to-park QSO with him. After that, I found a clear frequency and started calling CQ. Even though the band conditions app showed poor daytime conditions on 40M, I had my first ten contacts in about 15 minutes. Not too bad, actually.

Band conditions this morning. The 40M was pretty good, despite the predicted poor conditions.

After logging 20 contacts on 40M, I gave 20M a go. That band was good for another 22 contacts, including three European hunters. I moved up to 17M and made six more contacts, five of which were European stations. I seemed to have a pipeline into Poland this morning on 17M.

After 90 minutes of operating, I had 48 in the log. The DX stations included:

20M: Sweden, Belgium, and Denmark
17M: Finland, Poland (3), and Switzerland

Even with an unsettled geomagnetic field, I was pleased with my results. Of course, a QRP-portable outing with questionable band conditions is better than not getting out at all.

The Ashi Paddle 45

After my inexpensive QU-21C paddles started acting up again during a recent activation, I went on a paddle binge, ordering some new, reasonably-priced paddles to try out. First up was the CWMouse paddles, which I really like. Next was the Ashi Paddle 45 purchased from N6ARA Electronics.

The paddles are designed and built by 7L4WVU in Japan and imported by N6ARA. I’ve had my eye on these paddles for a while, so I thought I’d buy them and give them a go.

After using the Ashi paddles on a few POTA/WWFF activations, I thought I’d document my impressions.

General: I was looking for small paddles to keep in my Elecraft KH1 kit, and the Ashi Paddle 45 fits the bill. They measure approximately 1-1/16″ x 2-1/8″ x 1″ (27mm x 54mm x 25.4mm) and weigh just 1.1 ounce (32g) with the magnetic mount attached. They are constructed from high quality 3D printing, and come with two mounting options: a magnetic mount and a leg strap. Two screws are provided for attaching the paddles to the mount you choose.

The Ashi Paddle 45 leg mount (left), the paddles with the magnetic mount attached (upper right), and the protective case for the paddles.

Overall Feel: Like the CWMouse paddles, the Ashi Paddle 45 uses microswitches for the contacts. Thus, the tension and throw are not adjustable. Of course, paddle spacing and tension are matters of personal preference. Being an Iambic Mode B user, timing is critical, so I prefer narrow spacing and light tension. The Ashi paddles’ spacing seems slightly wider than the CWMouse paddles, and the tension feels just a bit heavier.

When I first started using the Ashi paddles, I would occasionally get an extraneous “dit” when forming characters with a single squeeze, like the letter K. My guess is the microswitches are a little slow breaking contact after releasing the paddles. I have to send more deliberately and remove my fingers completely from the paddles after each character. Fortunately, it didn’t take long to get used to the feel, and I had no issues sending with the paddles. Of course, this is all based on my personal preferences, so your mileage may—and probably will—vary.

The Ashi paddles attached magnetically to my clipboard

Mounting: My preferred method of sending is with the paddles attached magnetically to my little clipboard or a kneeboard for my KH1. So, naturally, I tried the magnetic mount first. Like my QU-21C paddles, the body of the key is small relative to the paddles. This makes magnetic mounting problematic. When I attach the paddles to a steel surface (like on my clipboard), they have a tendency to move side to side when keying. I have to use my hand to keep them steady. Not a huge thing, but I’d prefer they didn’t move at all. I have an idea in mind for an improved magnetic mount. If that works out, I’ll do a separate post on it.

Using the Ashi paddles on a KH1 kneeboard

I haven’t used the leg mount in the field, but it worked great in the shack. That would probably be a great mounting option in some situations. The leg mount is cleverly designed so that you can angle the paddles to the left or right, if you like.

Overall, I like these paddles. Once I adapted to the feel, they worked reliably in the field. So, the Ashi paddles definitely replaced my quirky QU-21C paddles in my backpack.

KH1 Picnic Table Ops

My (far) better half and I had plans to go watch our grandson’s soccer game yesterday, but I still squeezed in a short, early morning activation. I headed over to nearby Valley Forge National Historical Park (US-0761, KFF-0761) and allotted myself an hour of operating time. While I was there, I tried out a few things with my Elecraft KH1.

I set up the KH1 at a picnic table and used the whip antenna and AXE1 extender coil. I supported the antenna with a right-angle adapter from Tufteln. This was the first opportunity I had to use the adapter, so I was anxious to try it out. For my counterpoise, I used a homebrew setup with a 13-ft wire and a 20-foot extension for 40M.

The KH1 with the AXE1 loading coil for 40M/30M and the Tufteln right-angle adapter.

I also gave my CWMouse paddles another go. I glued four small magnets to them the night before, so I wanted to see how they worked with my clipboard. KE8PTX had a Facebook post recently in which he mentioned using painter’s tape on the metal surface of his knee board to give his paddles a little extra traction. As luck would have it, I was doing some painting this week and had some tape handy. I put some on the steel strips on my clipboard right before I left the house.

I glued some magnets to my CWMouse paddles. The blue painter's tape helps the magnets get a better grip. You can see the notation I made in my log for my 10th contact. — I glued some magnets to my CWMouse paddles. The blue painter’s tape helps the magnets get a better grip on the steel strips glued to the clipboard. You can also see the notation I made in my log for my 10th contact.

With everything set up, I tuned up the KH1 and got started. My results on 40M really surprised me. Although my signal reports were on the low side, I was getting some decent spots on the Reverse Beacon Network. It took only 13 minutes to log my first 10 contacts. I continued making contacts for 30 minutes, while brushing ants off of my log. (I think there was an anthill under the picnic table. Doh!)

I spent the rest of my hour-long activation on 30M and 20M. There was less activity there, but I picked up a few more contacts on each band.

When my hour was up, I packed up and gave the ants exclusive use of the picnic table. I finished up with 25 contacts in my log; I’ve done much worse with much better antennas. The KH1 did an amazing job with just the whip antenna, and my modified CWMouse paddles worked great attached to my clipboard.

As you can probably tell, I’m having fun with my new rig.

POTA with the CWMouse Paddles

I did a POTA/WWFF activation this morning and used it as an opportunity to try out a new set of paddles. During a recent activation, I encountered a recurring problem with the cheap QU-21C paddles I keep in my backpack as a backup. As a result, the finicky paddles have lost out on their role as my backup.

Always a sucker for unusual paddles, I came across an interesting offering I couldn’t resist. I fired off an order for the CWMouse paddles and had them in my hot little hands two days later. Mike KN6FQM designed the CWMouse paddles, which are currently selling on Amazon for $39.00 (US).

The CWMouse paddles are made from 3D-printed parts and include sealed ball bearing races, two sealed microswitches, and an ⅛-inch stereo jack. One thing that drew me to these paddles was the small size: 74mm/2.9in L x 36mm/1.4in W x 28mm/1.1in H. They weigh a mere 1.5oz/45g, making them ideal for portable use. See the CWMouse website for the complete specifications.

My destination this morning was Marsh Creek State Park (US-1380, KFF-1380). I usually operate near one of the boat launches, which can sometimes get crowded during the summer. Given that it was a weekday in September, there was plenty of room in the parking lot.

My rig today was my Elecraft KH1 into a 12-foot whip and homebrew loading coil. Starting out on 40M, I found lots of strong signals. I made a couple of quick park-to-park contacts before settling on a frequency and calling CQ. I quickly achieved the required 10 contacts and then some.

My KH1 fit nicely on the center console of my truck.

After 20 minutes, the activity on 40M tapered off, so I moved up to 20M. The action wasn’t as busy on 20M, but I made 11 contacts. One of those was with a station in California—I like when that happens. The 17M band produced three more before I called it quits. After a bit more than an hour, I had logged 32 contacts with six park-to-park contacts.

The CWMouse paddles performed flawlessly. Because of the microswitches, there are no adjustments for throw or tension. However, they felt great right out of the box. They have a nice, light touch, which is what I prefer.

One potential issue is the plastic used for the 3D printing. The website is very clear that the paddles should not be stored at temperatures above 100F. This could easily happen in a closed vehicle, so I’ll have to keep that in mind.

I used the “two-handed” technique with the paddles this morning, which is not my preferred way of operating. I’ll probably glue on some magnets, so I can attach the paddles to my clipboard.

Overall, however, I really like these paddles. It was a pleasure operating with them this morning.

Paddle Problems & POTA

My (far) better half and I spent the past weekend with family out in central Pennsylvania. During the weekend, I squeezed in a quick, early morning POTA activation. The great band conditions made for a fun activation, but paddle problems made it challenging at one point.

On Saturday morning, I was up before everyone else. After downing a cup of coffee, I took a short drive to a boat launch on the Susquehanna River to activate the Captain John Smith Chesapeake National Historic Trail (US-4567).

We drove out in my (far) better half’s car, so I used a simple antenna setup that produced decent results in the past. I used my Gabil GRA-7350TC on a small magnetic mount. Like the last time I used it on my (far) better half’s car, I easily adjusted it for a 1.3:1 SWR on 40M. I fed the coax through the passenger side window.

Gabil GRA-7350TC antenna on a magnetic mount

Inside the car, I set my Elecraft KH1 on the center console. I used my cheap QU-21C paddles attached to a clipboard with a homebrew magnetic mount I made for them.

The 40M band was hot with no trace of the QRM I experienced the last time I was there. It only took 14 minutes to log my first 10 contacts, the contacts came in steadily for the next 45 minutes.

I was cruising right along for about 30 minutes until my cheap paddles decided to start dropping “dits” here and there. Based on my crazy sending, I’m sure some folks thought I was experiencing some sort of medical emergency.

I frantically searched for my N6ARA Tiny Paddle that I always carry as a backup. Of course, they were nowhere to be found. I ended up using the stock KH1 paddles attached to the radio, with the KH1 on the center armrest. This setup was an ergonomic nightmare, with my elbow in the backseat area. Despite the awkward position I was in, I was able to finish up my activation.

My setup after my paddle problems started. On hindsight, I could have arranged things better to make my operating position a little less awkward.

After an hour, I had 39 contacts in my log. I was so occupied on 40M, I never got around to trying the higher bands. My log included 7 park-to-park contacts. One of those was with N4JAW (aka Ham on a Bike). It’s always fun working Jim down in Kentucky.

I also heard from my friend, Greg WA3GM. It had been a while since our last QSO, so it was great to hear him again.

The Gabil antenna and mag mount setup once again proved to be a great antenna when using my (far) better half’s car. With about 4.5 watts out on 40M, I worked stations up and down eastern U.S. and Canada and out to several mid-west states.

The QU-21C paddles, however, are a different story. This is the second time I have had issues with them. A squirt or two of contact cleaner will usually fix the problem—for a while, anyway. As they say: You buy cheap, you get cheap.

And, of course, I found my N6ARA paddles as I was packing up. Doh!

Going with Plan C

I set off this morning to activate Norristown Farm State Park (US-4363, KFF-4363) with a specific plan in mind. We’re talking about me, of course; so things don’t always go as planned. Today was a good example of that.

If a specific parking space was available, I planned to use a loaded whip on my truck and operate from a nearby park bench. Failing that, I figured I would set up at one of the picnic pavilions with a vertical of some sort. When I rolled in, however, the parking lot was crowded and people were setting up for an event under the pavilions. So, I was off to come up with a Plan C.

I drove back up the road a bit and pulled into a mostly empty trailhead parking lot. Off to one side, I found a secluded picnic table tucked away in a wooded area. About five minutes later, I was on the air.

My Elecraft KH1 with the antenna off in the distance

I sometimes think that my 50+ years of ham radio have been an ongoing quest to simplify my operations. My recently acquired KH1 is definitely a giant step in that direction. Everything I need (except for my earbuds) is attached to the radio.

Looking at the propagation forecast, I opted to forego the KH1’s whip antenna and go with something larger. So, I went with the 9:1 end-fed random wire from AD8HK Antenna Systems mounted on a cheap 19-foot telescopic pole. The ground was a little soft, so it took me a few tries with my homebrew ground mount to get the antenna reasonably vertical.

Even with a vertical just under 18 feet, the 40M band was productive today. After eight quick‌ contacts, things slowed down, and I changed bands. The 30M band produced one contact, while 20M was good for a half-dozen more. I went back down to 40M to pick up a few more before calling it quits. After about an hour, I ended up with 18 contacts, five of which were park-to-park.

My Elecraft KH1 at Norristown Farm State Park (US-4353, KFF-4363)

I have to say I’m really having fun with the KH1. It’s ideal for the short activations I tend to do. The battery life is nothing short of exceptional. This was the second activation since I last charged it, and I could probably do four or five more.
