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.

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.

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.

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.

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.

WES & POTA at Ridley Creek

I made some contacts in the monthly Straight Key Century Club (SKCC) Weekend Sprintathon (WES) this morning and completed a POTA activation while I was at it. My operating site today was Ridley Creek State Park (US-1414, KFF-1414).

I rolled into one of my favorite spots and set up my table and chair in the grass behind my truck. From previous activations, I knew this spot always has lots of shade. Of course, with the heavily overcast skies this morning, sun exposure wasn’t much of an issue.

I mounted a 17-foot whip and my homebrew loading coil on my truck and ran some coax back to my operating position. Rig-wise, I used my Penntek TR-35 (5 watts, CW), Elecraft T1 tuner and my little American Morse MS2 straight key.

My strategy today was to operate in the WES for an hour. If I hadn’t reached 10 contacts by then, I planned to break out the paddles and finish up as a POTA activator.

It was a good thing I had a “Plan B.” After an hour, I had only scratched together six WES contacts. I don’t know if it was the unsettled geomagnetic conditions or just a lack of early morning participants, but I didn’t hear much WES activity on 40M and 20M.

After spotting myself on the POTA and WWFF websites, I easily made the requisite 10 contacts on 20M plus three more for good measure. One of those contacts was a park-to-park.

It wasn’t my best outing, but far from my worst. Even with the humid weather and the occasional mosquito, it was nice to do a little outdoor operating and log some familiar SKCC and POTA callsigns.

Puppy Sitting Again

I recently spent six days out in Central Pennsylvania on house- & puppy sitting duty again. I got to spend some quality time with my grand-dog, Belle, and got in some radio time, too.

PA State Game Land 246 (US-8941, KFF-5862)

My first radio outing was early on a Friday morning. Pennsylvania State Game Lands 246 is only about 10 minutes away, so it’s perfect for a quick activation. With an active geomagnetic field, the propagation didn’t look at all promising. I ignored all that and headed out the door. As I was leaving, Belle thought we were going for another walk. Needless to say, I had a very disappointed German shepherd at the window watching me leave.

The parking lot at SGL246 was empty when I got there. I set up my 12-foot whip and homebrew loading coil, along with my trusty Penntek TR-35 (5 watts, CW). I spent the whole activation—and it was a short one—on 40M.

My truck at PA State Game Lands 246 — State Game Lands 246 (US-8941, KFF-5862)

Given the band conditions and the early hour (around 0745 local) on a weekday, I got off to a slow start. My big issue was the local power line noise. Before I started, I tuned around 40M to find a frequency where the noise was lower. Despite the band conditions and noise, I seemed to be getting out well enough, and the received signals were fairly strong.

After 30 minutes on the air, I finished up with 14 contacts. I packed up my gear and headed back to take Belle for that walk. After that, I think she forgave me for leaving without her.

And Then the Rains Came

Bright and early Saturday morning, I took Belle through the basement to let her out in the backyard. I found myself splashing through puddles of water in the rec room, and the sump pump was running like crazy.

We had some severe thunderstorms the previous night, and according to the local news, we received close to two inches of rain overnight. So, much of the day was spent cleaning up and drying out instead of playing radio. Fortunately, my (far) better half drove out for the weekend and helped with the cleanup effort.

Capt. John Smith Chesapeake National Historic Trail (US-4567)

When I woke up Sunday morning, I saw we were in the midst of a severe geomagnetic storm. Some hams on a local repeater were complaining about the poor conditions on the HF bands. So, what did I do? I headed out for an early morning QRP POTA activation.

For this water trail, I went to a public boat launch on the Susquehanna River. The river was still slightly flooded from the recent rainstorms, but the water hadn’t reached the parking lot.

Some minor flooding of the Susquehanna River — Some minor flooding on the Susquehanna River

Given the poor band conditions, I used my homebrew loading coil and a 17-foot whip instead of my usual 12-foot whip. I was hoping the additional five feet would help my 5 watt signal punch through the geomagnetic storm.

I also used my brand new Pocket Paddles from CWMorse. I neglected to order one with magnets, so I couldn’t attach it to my clipboard. However, I think I have a plan to address that as a future project. On the air, the Pocket Paddles performed flawlessly, and I’m looking forward to using them a lot more in the future.

After my third CQ call on 40M, I quickly logged my first two contacts. The contacts kept coming, but at a slow pace. After nine contacts, I thought that the tenth one might never come. Fortunately, it did. After 45 minutes, I ended up with 12 contacts, including one park-to-park. Not bad for a severe geomagnetic storm. I packed up and headed to a grocery store to pick up a few things for breakfast back at the house.

And Back to PA SGL246

On Monday morning I made another trip over to PA State Game Lands 246. There was a major geomagnetic storm in progress, so I knew this would be another challenging activation.

The parking lot was empty the whole time I was there. No big surprise, given that it was early on a weekday. I went with the same set-up as yesterday, opting for the 17-ft whip.

With a K Index of six and the usual power line noise, it was slow going on 40M. It took a few minutes of continuous CQing to log my first contact. It took almost 45 minutes to get seven in the log. At that point, things stalled for a bit. Around that time, I received a NOAA email alert saying the K Index had increased to seven.

I had allotted an hour for this activation, and I was getting close to the end. Then, out of nowhere, I had three callers in rapid succession that got me to 10 contacts. For good measure, there were three more after that.

I finished up with 13 in the log, with one known park-to-park contact. So, my little five-watt station managed to pull it off again. Take that, Mr. Sun!

And with that, I wrapped up my activations out here. Radio-wise, the band conditions were challenging, but it was still fun. I might be back in central Pennsylvania for another round of puppy sitting next month—with better band conditions, I hope!

No-Name Mini Straight Key

I needed another mini straight key like a hole in the head. With my fascination for these things, however, I just couldn’t help myself.

The key in question came from AliExpress and cost me about $18 USD. Although it has no markings on it, it appears to be from the same manufacturer as the QU-21C paddles I bought a while back. The basic design is the same as the QU-21C, and it came with identical packaging and accessories. After modifying the magnetic base, the paddles have served me well. So I took a chance on the look-alike straight key.

The key is magnetically attached to steel strips I glued to my clipboard. — My no-name mini straight key from AliExpress during a recent portable outing. The key is magnetically attached to steel strips I glued to my clipboard.

Out of the box, the straight key’s contact spacing was a little wide for my taste. Using the included Allen wrench, I adjusted the key more to my liking. For a cheap key, it has a pretty good feel to it, and it keys cleanly.

The accessories that came with the mini straight key. (Not shown is an adhesive rubber square that I attached to the bottom of the key.)

Based on my experience with the QU-21C paddles, I had some reservations about the highly polished square magnet on the bottom. However, since the motion of the straight key is the vertical plane instead of side-to-side, the magnet is less of an issue.

I used the key during a recent outing, and I had no major issues with it. I have some a couple of steel strips glued to my clipboard, and I stuck the key there. There was a little movement, but nowhere near as bad as the paddles. I just needed to make sure I didn’t get too vigorous with my keying. After I use them some more, I’ll decide if I want to modify them like I did with the paddles.

Most of the time I get what I pay for, but in this case, I think I got a decent product for the price. I let you know if my opinion changes with time.

Captain John Smith Trail

I was out in central Pennsylvania over the past weekend for our family’s belated Thanksgiving get-together. Before we left for home on Sunday, I squeezed in a quick early-morning POTA activation. This time, I drove down to Falmouth Boat Launch to activate the Captain John Smith Chesapeake National Historic Trail (US-4567).

The Falmouth launch is about two miles downstream from the infamous Three Mile Island Nuclear Generating Station. I was here once before back in 2018. However, I had forgotten that this water trail includes the entire length of the Susquehanna River. (I have since uploaded that log to the POTA website.)

It was about 20F (-7C) when I headed out for the 15-minute drive to the site. The parking lot was nearly empty, so I was able to park in a spot that fell within the 100 feet guideline. I had previously used Google Earth to measure the distance to the river.

I quickly put up my 12-foot loaded whip (before my fingers got numb) and set up my Penntek TR-35 (5 watts CW). Thankfully, the sun and my body heat brought the cab of the truck up to 40F (4C) in short order.

The conditions on 40M were amazing. The first two stations answered my CQs before I had even spotted myself. When I finally posted my spot, I had a huge pile-up. There were a lot of early risers out there, so Craig was a very busy boy for the first 15 minutes or so.

I gave the cheap QU-21C paddles a real workout this morning. My quick and dirty magnetic mount held perfectly, and the paddles worked great. They’ll be seeing a lot more use in the future.

After 33 minutes on the air, I had worked 32 stations, all of them on 40M. I had one known park-to-park.

Then, it was time to head back to my daughter’s house for breakfast. On the way, I pulled over to take some pictures of Three Mile Island. I also saw another boat launch that I’ll have to check out further.

Hacking the QU-21 Mini Paddles

When I bought the QU-21C Mini Paddles a while back, I wasn’t crazy about the small square magnet attached to the base. It didn’t seem to hold very well. When subjected to vigorous keying, the paddles would sometimes move side-to-side. I came up with a quick and dirty hack that resolved the issue for me.

A little backstory is in order. I’ve never been a big fan of “two-handed” keying; that is, holding the paddles in one hand while sending with the other. I modified a small clipboard by gluing two steel washers to it, such that they lined up with the two magnets in my Palm Mini paddles. The clipboard securely holds the paddles and gives me a nice writing surface for logging in the field. I’ve been using clipboards like this for about 10 years now.

In just a few minutes, I modified my QU-21C paddles to adapt them to my clipboards and make them more suitable for “single-handed” keying. The first order of business was to remove the square magnet from the bottom of the paddles. That was almost too easy. I wedged a knife blade between the base and the magnet, and the magnet popped right off.

Magnets glued to the underside of the perf board to line up with the steel washers on my clipboard

Next, I took some perf board from my junk box and cut off a 3.5 x 1 inch piece. I used some Goop® adhesive to attach two magnets on one side of the board. I placed them so they had the same spacing as the magnets on my Palm paddles. Then I glued the QU-21C paddles to the other side of the perf board. Except for the drying time for the adhesive, I completed the project in about 10 minutes.

The QU-21 paddles glued to the perf board and ready for use

The magnets I used are really strong and probably overkill for this application. But, I had a bunch of them on hand, so I put them to use.

Admittedly, this cheesy little hack doesn’t look like much. If I feel ambitious sometime, I might come up with something more elaborate. Maybe something like the base I made for my little MS2 straight key. For now, though, this will suffice.
