This is a reference to a page within
's terrific website:
The Telegraph Office.
It is taken from Chapter 6 of Army Technical Manual TM 11-459, September
1957, Ch. 6, para. 31: SEMIAUTOMATIC KEY, USE.
This is a great reference PDF I found on
You may download it here-or go to their Online-Manuals section. It is
a copy of a copy that seems to have originated with Vibroplex, and at
some point was published in QST many years ago. It is an excellent
reference on this subject.
This is my
Dow Key Chrome Rotatable-Yoke BUG.
It is in amazing, beautiful, near- mint condition, as you can see. It came
with the original wooden carrying case, marked
Dow-Key. It is one of
the finest keys I own. Click on the photos for the hi-rez versions.
