The second third beta release of my #HamRadio #MorseCode single-paddle key is out. The spring weights have been adjusted based on some feedback. Each key has an identifier associated with the weight on the bottom to make it easy to tell them apart. There is now a separate mounting plate for a clipboard or forearm plate like Dan WY3O brought to the RARS meetup.

It's not actually necessary to use ring terminals, especially while experimenting. You might want them on a final version, but while testing, bare wires under the lock nuts and center screw are probably good enough. If I were carrying this POTA or SOTA, though, I'd want the ring terminals for durability.

I'm eager for feedback, and if I get time to print off a new batch tomorrow, I might bring a set to RARSfest Saturday.

If you have a local ham club with several people interested in this key, you can buy brass hardware, and with the links in the README can buy enough to make 5 keys for $50 (with a bunch left over because of different multiples, of course). I did this because I intend to make several of these keys for testing and display.

But it works fine with far cheaper stainless hardware; brass just looks nicer. As far as I can tell, most hardware stores even in the US have M3 metric hex socket screws in bins, so you don't have to buy 10-packs or 50-packs of hardware. This works perfectly fine. You just need a hex wrench and a small box-end wrench or needle nose pliers or forceps/hemostats or something to tighten the nuts when you adjust spacing.

My goal here is to help make it cheap and easy to have a really usable key.

And if you run into any problems, please please ask for help! The whole point of the beta release is to get feedback so I can improve both the models and the instructions before posting this more widely.

This design is ready for you to test!

I printed out keys with six different variations on spring strength, four different sizes of covers, two different heights of swivel bases, and brought them all to my local club monthly show-and-tell. A few others club members have also printed them. I took some feedback, and have now updated the documentation and released STEP and STL files for multiple configurations.

The ones I printed were ABS. One club member printed in PLA, and another in PETG, so it looks like this design can work well across multiple types of filament. One club member screwed down what I had meant as a belt swivel mount to a board that you rest your wrist/forearm on and it's a very clever addition! Picture attached.

I would like lots of detailed feedback! If you are interested in a single-paddle morse key, it doesn't matter whether you want a very light or extremely stiff spring or anything in between, this design can meet your needs. It's not expensive. You may be able to use random hardware lying around the house, especially if you have spare parts for 3d printers, but I also have links in the documentation for various hardware you can use with it.

Lots of options and possibilities, and if you need help, please don't hesitate to speak up!

There's a non-null probability that I'll soon put the following global #CW on top of my profile:

"Caution: the older I get, the more I feel enclined to repost every great photography I encounter. Taste police and optimized posting zealots can consider themselves warned."

Questions for people that have experience with morse code via signal lamps (Aldis lamps):

- did you learn morse code audibly before/alongside/after visual CW?
- if you knew or learned audible, was the transition to lights "hear the light in your mind", or is it a totally different mental pathway, with no cross-over?
- if you knew or learned both, would one be the preferred first exposure to Morse Code?
- if you practiced outside a training facility, how did you do copy practice?

I'm not much of a contester personally, but I have a soft spot for #SST. While it's technically a "contest", it feels more like "slow down and encourage newcomers to try #CW". The first time I ever got on the air and tried #morse was for SST a few weeks ago.

Too bad I don't have a permanent antenna install, so can rarely dive in. Maybe I'll monitor using a web SDR.

This is a long winded reminder that SST kicks off in about 2 hours.

Besides, it has the coolest sounding CQ call!

On Sunday I've done the first parks on the air #POTA activation using morse code #CW. I was able to log 11 CW contacts on 20m and 40m.
I was afraid that there would be too many stations calling me at the same time but that did not come true. The operators I worked were slowing down for me which made it an exciting but pleasant experience. I'll definitely do it again.

So I had some CW skeds on the groundwave and my course is progressing, but I still don't dare to answer calls on HF. Is anyone interested in a QRS shortwave sked? 10 m, 20 m or 40 m preferred. (WARC bands between 10 m and 20 m are possible, too, but I don't have /m antenna for those bands and my car is a weatherproof option)

Ich würde mir wirklich wünschen, dass man auch Re-Tröts mit einer #CW versehen könnte. Wirklich! Ich krieg so viele Re-Tröts bei denen ich mir das so sehr wünschen würde und es hält mich auch vom Re-Tröten ab.

Besonders bei Zeitungsartikeln aktuell wäre ich für Politikwarnungen etc pp sehr sehr dankbar!

Verstehe natürlich gleichzeitig, dass Nachrichtenagenturen nicht alles CW-en können von sich aus. Daher der Wunsch es bei Re-Tröts zu ermöglichen.
