first keyer
Locked
 
|
Ah ............. my first keyer came from Bell Labs! Funny round things in
it. Had 3 leads and a tab on the funny case. Used a mercury wetted relay in a great big tube like a shot gun shell. Gee, I wish now I had that schematic! It worked great and was all scavenged from boards at work. I wonder what I used as a paddle? Don't remember, maybe my bug or a couple of J-38's base to base and vertical ? Talk about an interesting build, that was IT !! The must have been NPN as they were everywhere then if I remember right.

First keyers... remember the Mon-Key?
A pair of dual triode 12AU7s. One triode of one tube produced dits while the other produced dahs using a multivibrator circuit. The other tube, one triode drove a speaker while the other drove a keying relay. Dits and dahs were not self-completing, so it was tricky to hold the dah paddle down until the timing was completed, otherwise a zero might come out as a nine. de Joe, aa4nn _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Mark:
I, too, built the WB4VVF Accukeyer and it was 1973, I believe. The memory boards were added a year later. I remember as I was a Junior in high school !! I also remember the output transistors were easy to blow ! Probably due to my nascent soldering skills ! HI I still have it in my storage. 73, Jamie WB4YDL -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Mark Bayern Sent: Monday, September 10, 2007 4:30 PM To: Joe-aa4nn Cc: Elecraft List Subject: Re: [Elecraft] first keyer >>"Ah ............. my first keyer came from Bell Labs!

Was that the one in the ARRL Handbook around 1958 - 1961? I built one and
used it for years. I had to make my own key for it, took two J-38 paddles and mated them back to back and re configured the contacts etc. A key came on the market called (get this) an ElKey, and I bought one. Used it until I bought my Simple single arm no Iambic yet. I made two solid state keyers that didn't work as well. That first keyer had weight and ratio control and auto complete so it really gave a good fist. And it made enough noise you didn't need a monitor to hear what you were sending. I sold it about 10 years later when I bought my bencher and a AEA Morsematic.

I still have my WB4VVF Accukeyer, too. (:-))
And a couple of spare octal-based mercury wetted relays for the Hallicrafters "TO" keyer. FWIW, the HexKey is wonderful, and the Elecraft logo makes it work even better..... 73!

I built the one in the handbook and used if for many years. It had one sawtooth generator and it oscillated at different frequencies, one for dashes and one for dots. The other half of that 12AU7 was the rectifier tube. The other 12AU7 formed the clipping circuit that clipped the tops off the sawtooth waves and drove the keying relay. Actually, half of that tube clipped the sawtooths the other half set the clipping level -- essentially the keying weight. There was no monitor circuit or speaker in that design. Also it did, as you point out, self complete each dot or dash. It was a cool design and I used it in many a Sweepstakes and CD party. I also built the 4-400 amp and a 6C4 based TR switch out of the same issue of the handbook. It was the 1961 Handbook although I was using it in 1965 and later. Man, that was a long time ago.. 73, -Doug, W7KF _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Love that thing although the old keyers don't have dot or dash memory so I can hardly send on those things anymore. (BTW, in case you've never used one of the ancient keyers, having no dot or dash memory (auto-complete?) means that if your brain and hand are sending characters faster than the keyer then things will get lost. For example, if you send the letter N and your keying was such that you sent the trailing dot before the keyer finished sending the initial dash then the trailing dot would be lost and you would have sent a T.) 73, -Doug, W7KF _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Sorry, but the value of yours will be diluted by the fact that I still
have mine, built in the seventies, I think, from a Dick Smith kit. Mine has the incomparable Galbraith paddles (from ZL) in the front panel. It will key both transistorised rigs and glowbugs. It also has a Tone IN socket connected to a rectifier so that it can be keyed from a tape recording. This was added in the days I was a slow Morse operator in VK6. 73 Kevin VK3DAP / ZL2DAP Ron D'Eau Claire wrote: > I have my CMOS Accu-keyer built in the 1970's from the QST article.
