Idiom Press CMOS-4 ( emulation of other keyers)

[dw-4]

Hey All,

The CMOS-4 advertisement indicates that it can emulate other keyers.
I'm guessing that means that it emulates their weighting
characteristics??

The Logi-key.... the Curtis "A" timing..... and the Accukeyer.

Since I'm not familiar with those keyers, I wonder what distinct
characteristics are being emulated.
Are those keyers noted as having some peculiar characteristics?

Just wondering if anyone....off the top of your head......could
recollect any special differences?

I built an Accu-Keyer in 1973. If you are an ARRL member you can see a rather poor copy of the original article here:

http://p1k.arrl.org/cgi-bin/topdf.cgi?id=62617&pub=qst

The Accu-Keyer has self-completing dots and dashes, dot and dash memories, iambic operation, dot and dash insertion and automatic character spacing.

The Accu-Keyer spawned the Accu-Memory (http://p1k.arrl.org/cgi-bin/topdf.cgi?id=67877&pub=qst) which added memory storage.  I built a couple of these, giving one to my friend George, W6TC, and adding another couple of circuit boards full of TTL ICs to another one for myself that added automatic changeover sequencing, transmit/receive timing, etc. for automating my EME and meteor scatter schedules. It's still out in my storage building.  Another thing for my widow to dispose of.

The Logikey and Curtis stuff basically has the capability of emulating some or part of the features of the Accu-Keyer.

It was the Accu-Keyer that finally displaced the Lightning Bug,  
although I still have the bug and still use it.

It was probably one of the most popular iambic keyers of all time, and  
they occasionally show up on eBay in various states of disrepair.  I  
still have the original I built from the first 1973 QST article.  It  
has a nice feel, is easy to use, and the auto character space feature  
cleans up a lot of slop.  The CMOS-4 is virtually identical in Accu-
Keyer emulation mode.  It's like old home week :-)

Musts been a -lot- of AccuKeyers built!  I still have mine.

I even took it to sea with me ...

I think there's even a bag of spare IC's inside the cabinet.... (:-))
