Re: [cw_bugs] varispeed
- Fred - everything you do is so beautiful!
Regarding 25 wpm on a hand key, you're fast! I still have a challange
out for anyone who can produce a recording of 25 wpm on a hand key.
So far, I've had three people who said they could do it, but when they
measured it, they found that they could not.
I have a commercial first-class telegraph license which was tested to
send and receive at 25 wpm. Fortunatly for me the USA is the only
country where we are allowed to use a semi-automatic key for sending
and a typewriter for receiving. The other code tests (20 wpm code
groups) have to be done by hand with pen and hand key.
I learned the virtues of a hand key by operating on 500 kHz during
QRN. You can really control a hand key like you can't control any
other key other than a sideswiper.
One ex RAF CW operator applied for a job as a maritime sparks - and he
was turned down because he couldn't send like a merchant operator - we
prolong our dots so they can make it through the QRN.

Please do have at it, but for me, Morse becomes laborious below about 25 wpm because it loses its language characteristic and returns to being a cipher. Since I can't make 25 wpm Cw with a straight key for more than a few minutes, it is a bug and a pddle for me.
> DR, I coveted the original FYO paddle when I was a youngster, so much so, that I made my own rendition of it. my rendition, from the 1963 QST article, was a dual lever, and possibly the first dual lever version of the FYO's idea, I don't know. It was 1963 well before Bencher, and before FYO produced the paddle. I still have that paddle, and other than being light because I built it on a walnut base, it works very well.
> The wood was cut by hand. The levers were hand cut with a hacksaw, and bent in a vise. The contact posts borrowed from a J-36. The pins supporting the levers are nails filed to a point. The ratio from pivot to contact versus pivot to finger piece is 1.5:1 such that the gap is made to feel smaller than it really is. The key can be adjusted to where you can not feel it move.
