Just wondering who may use the CW touch keyer and how they find it...?

I have purchased one and find them pretty good for what i do, still need to stop making silly sending mistakes, by brushing the contacts..

regards,

I have one and I love it.  I have gotten rid of all my mechanical keyers (except my Palm Mini).
I was forever adjusting my Iambics trying to get the light touch I like, I could never get it right.
The CW touch keyer does take a little getting used to because it will key if your finger lightly brushes
it, but I now find I can send smoother and more accurately than I could with any of my mechanicals.
It is so good/easy I find my self getting lazy and that's when I make brushing errors.  I'll never go back.

Best,

Although I do not own a capacitive touch key, I've tried them. I like them better than my Begali Pro. That's why I've never bought one. The purchase of one,  would admit that the fine craftsmanship of an Italian Artist has been bettered by electronics. I can't go there even though my heart tells me the truth.

Hi Derek....

Congrats to all the guys who have mastered those capacitive paddles.

I tried it, and gave up in very short order.  I think it's because I spent so many years using a bug, and never developed the light touch needed for such a key.

Couldn't use a Bencher paddle for the same reason.  I treat 'em too rough.  At higher speeds, I'd be in the middle of a sentence and the thing would fly apart like a homemade hand grenade.

Now I waffle between a bug and Vibroplex's Deluxe Square Racers.

For guys like me (and Phil ?), a couple of tin-foiled bricks to slap
together would work fine.

Personally, my hands sweat too much for the capacitive types.

My fingers get too wet, and I end up with premature capacitation.

I built a Heath Micromatic keyer with capacitive paddles. sensitivity varied with humidity and skin moisture levels. Never did get comfortable with it. Have a Heath HD-1410- just using the paddles now with IC-746Pro, and built a PortaPaddle II to use with IC-703. Very nice feel.

I just love mine. It's the only capacitive-touch keyer I'm aware of. Are/were they made by anyone else?

Currently available:

http://www.cwtouchkeyer.com/

Assembled, kits, circuit boards, etc -- good reviews on eHam.

I seem to like "pressure-sensitive" keying.  I'm "choking-up" on my single paddle, moving my hand closer to the pivot.  The movement (side-to-side) is miniscule, but the force is fairly high.

I don't think the capacitive paddles would suit me.  But it's a very personal taste.

I have the cwtouchkeyer as mentioned above. I love it. I am new to amateur radio slow and with CW. The touchkeyer has made it easier for me.

A CTK is featured in the July CQ magazine for homebrew.

Looked interesting.

I have one I made. It is kinda weird for me to use after all these years of using a set of paddles.
Very different feel to it than paddles or single lever key.
Nothing you can't get used to though and they are inexpensive to make. I prefer paddles though.
No "click" when you touch it. No lever travel to adjust or anything else.
It is all in your fingers.
...just weird!
