No-Name CW Paddles

Once a day, I receive an email from eBay showing the latest listings for CW keys. In one of those emails, a small and inexpensive set of 3D-printed paddles caught grabbed my attention. My curiosity got the better of me, and I ordered some.

The primary reason for my interest was the size. I normally use Palm Mini paddles attached to a clipboard, when I’m out operating portable. The eBay listing offered paddles that were a bit smaller than my Palm Mini paddles. The Palm paddles are no longer available (much to my chagrin), so I was curious if these cheap paddles might be a viable alternative. Given the low price (around $15, shipping included), I had no delusions that the no-name paddles would be as good, though.

The paddles are “unbranded” and listed on eBay under the awkward title, “Cw key automatic key short wave automatic key double paddle radio report NEW.” There are numerous listings for these paddles. Most of them ship from Hong Kong but there are some U.S.-based sources. Some are available in kit form.

They are available in 3 sizes. The two larger paddles have magnetic bases. I bought the smallest one (3x8x2 cm), which had the potential to work with my clipboard setup. They are intended for two-handed operation but I figured I could improvise some sort of magnetic base for them.

As mentioned earlier, they are 3D-printed. The seller cautions: “Can’t work in high temperature environment!” The term, “high temperature,” is undefined. I’m sure I would start to wilt in the heat long before the paddles.

It took a couple of weeks to receive my paddles from Hong Kong. Besides the paddles, the package contained a 3-foot patch cable with 3.5mm stereo plugs. There was no documentation but none was needed.

Out of the box, I found the contact spacing to be much wider than I’m accustomed to. Fortunately, the paddles have access holes on each side to adjust the spacing. A few tweaks with a Phillips screwdriver got the spacing closer to my liking.  

It was easy to fashion a magnetic base. Using some two-sided foam mounting tape, I added two strong magnets to the bottom of the paddles. The magnets didn’t line up exactly with the washers on my clipboard but they held pretty well. 

You’re probably wondering how they work. Well, they are about what you’d expect from $15 paddles. For sure, they lack the solid, precise feel of my more expensive Palm paddles. The paddle arms have what I call, “vertical slop.” By that I mean you can wiggle them up and down. Also, the paddles’ contacts aren’t the greatest. They are just the threaded ends of two machine screws contacting the threads of a vertically-mounted machine screw. 

With the “vertical slop” and the rough contacts, you don’t always get clean contact closure. To me, it feels like the contacts sometimes “scratch” when they close. The left paddle also sticks occasionally. At higher speeds (20+WPM), they can be challenging. That said, I am able to coax decent-sounding code out of them at moderate speeds—if I’m careful.

As they say, you get what you pay for. These paddles won’t be replacing my Palm Mini paddles anytime soon. They don’t have the smooth, quality feel of my Palm paddles—or any other paddles I own. Not by a long shot. I concede, however, that comparing these $15 paddles to more expensive products is not entirely fair.

CW keys and paddles are always subject to personal preferences; however, if you are on a limited budget, these paddles might work for you. It certainly won’t cost you a lot to find out.
