Mon-Key
The Mon-Key was one of the first commercial made electronic keyers and was
manufactured by Electric Eye Equipment Co. at 6 West Fairchild Street
Danville, ill. The 1948 ads in QST list it as a Electronic Monitor and
Key. It has three tubes 2- 12AU7's and 1- 35W4 , Operates from 110 Volts
A.C. or D.C... Nominal speeds 10-42 WPM. Some of the ad states ......*It's
easy to operate....*easy to read. Press the key to the right for
dots....*out they come....*evenly spaced. Press it to the left and get
evenly spaced dashes. *Just relax and follow the key...*let the code roll
out with perfectly timed rhythm. Send fast or slow...*there's a dial
setting to regulate speed. Get on the air with a near perfect fist. It sold for
$29.95 . I found it very hard to operate, you really have to work at it.
All I could get was about 20 WPM out of it.
