Take a swipe at it
The "Cootie" key or "Sideswiper" is basically a double-sided straight key and has a reputation for being very hard to learn, possibly harder even than the Vibroplex Bug. My recent bug practice has been going well so I figured I would add a new level of difficulty by adding a completely different style of key into my brain mix...
A Cootie key

My Palm Paddle Single has an internal adjustment that turns it into a sideswiper...

That means that touching either side of the paddle closes the tip contact of the key jack, rather than operating the ring and the tip independently.
Google "cootie" and you come up with 'body louse'... well at least you come up with that definition. (hopefully you don't actually get body lice). We are talking about a different kind of cootie here...
Morse Express has an article with an excellent description and history of the cootie key here.
I had some interest in operating a sideswiper because a good friend of mine Kurt (N4KJK) uses one regularly and I admire his skill with it. I spent a short time in 2015 practicing with my Palm Single as a sideswiper and was horrible. I quickly gave up. Now with another year of CW in my brain and different types of keys (straight, iambic paddle and bug) swimming around my consciousness I took another shot.
I figured that I would spend an hour practicing side-swiperry and if I was making some progress I would continue the process, and maybe build a real side-swiper key using a hacksaw blade. Before building a key I wanted to practice with what I already had. I spent an hour this morning practicing sideswiper style with the Palm Single in Cootie mode and I went from really terrible to simply terrible, which in my book is great progress.
Level of Difficulty ?
You might have heard that the sideswiper is hard to learn... In general I'd say it is very different to what you may have already learned. If the sideswiper were the first key you tried to use you might have no more difficulty learning it that anything else. The problem is that it's completely different than EVERY OTHER morse key in the way it's operated.
The sideswiper is operated by swinging your thumb and forefinger back and forth rhythmically, where each opposing finger operates the key once for an individual element, rather than repeating any elements on one finger. For a straight key you are always operating in the same direction... down. Repeating elements, say the 3 DITS in an 'S' are repeated downward on the key. In the case of a paddle or bug, your left thumb is pressing to repeat the 3 elements of an 'S'. In the case of the letter 'O', your right index finger (or fingers) are accomplishing the repeating elements (DAHs in this case). In the case of the sideswiper/cootie each finger participates in repeating elements and the order in which finger begins the process is completely up to chance. So for an 'S' or an 'O' you might start with the thumb or the index finger depending on which finger last operated the key... the finger that's swinging toward the key at the time performs one element of the character then leaves the next element to the other finger...
"Arrrgh... it burns, it burns"
This is so completely different than operating other keys you simply must practice the mechanics that you've painstakingly built into your hand away to the beautiful simplicity of the cootie. Or at least that's what I'm telling myself.
So operating a bug takes some getting used to because you are timing the inter-character element transitions from index finger to thumb rather than an electronic keyer, but at least it's similar enough to a paddle that you are expecting to do the DAHs with your index and middle finger and your DITs are always accomplished by your thumb.
The old rules are gone. All your finely tuned muscle memory is thrown to the ether. You are freed of preconceptions of sending code and you become "Ambidextrous" with regard to DITs and DAHs. All your political affiliations are out the window as you now are able to approach a character from the RIGHT or LEFT.
Ok I'm obviously just being silly now but maybe you get my point. Give the sideswiper a try. It will absolutely clean plaque out of your brain. I'm fairly certain that just as learning and using Morse Code staves off brain disease... using all 4 types of Morse code keys in a round-robin fashion (Straight, Paddle, Bug and Cootie) will make your brain look like a young Arnold Schwarzenegger back in his Mr. Universe days.
Here's a demonstration after an hour of practice... be kind in the comments section :)
That's all for now
So lower your power and take a swipe at your key... from both directions
Hi, In my opinion you picked a bad example to practice with. I have the Palm as well and eventually put it back in normal paddle mode which is in the vehicle as an emergency back up in case the HK-706 should ever die. I do need to try adjusting the tension though. To give it another try I purchased the Bencher ST-1 which is also a single paddle key. It was much easier. It's sitting here on my desk. Hopefully soon I'll get brave enough to put it on the air. You're side swiping skill is better than mine. 73, Tim KE4KEReplyDelete
Tim, I agree the Palm single isn't ideal as a Cootie key. I certainly like it for portable operations.Delete
I just got a cootie and there is a slight learning curve but your comment about giving it an hour is so true. Wow, the cootie is a unique way to send. If only I had a biggre one :) Thanks for the video. appreciate it. 73 de Gary K8JCRDelete
But the "other guy" said that each character always begins with your finger. That's how I'm learning the cootie technique. Seems that it would be more difficult as you describe it. http://www.mtechnologies.com/cootie.htmReplyDelete
I had to modify my SKCC cootie key (purchased 2nd hand from N1EA) to tave full copper contacts, but since then it is now my favorite key. I go full cootie on it. That is to say, starting letters either way, opposite side, howsoever the last letter ended. Like so because I never yet used a bug. I would recommend starting out with a cootie in preference to an up/down key. It's half as much work. Easier on the wrist, just plain more efficient. And I can match speed against the other op without any fuss whatsoever.ReplyDelete
I like your way of doing the letters, so that the first key stroke of each letter begins in the opposite direction from the final key stroke of the preceding letter. That makes the concept of always alternating movements to be consistent.ReplyDelete
