USE OF SIGNAL CORPS TRAINING MANUALS
TRAINING MANUAL NUMBER 27
Radio Operator—Instructor's Guide
Part II—Code Practice—Volume I
This manual can be made of use to the Field Artillery, although generally
the Code Practice Equipment and the Ediphone will not be obtainable.
Sometimes suitable equipment can be improvised at a small expenditure of
private funds. Where this is undesirable, the two service buzzers issued to
battalions and higher units will have to be used. In general the system of
instruction laid down should be followed, omitting those portions of the text
which are obviously inapplicable. Information Topic No. 4, containing the
various tables of characters, will probably be found of most assistance. These
tables are carefully calculated on a speed basis and should be used in the
instruction at the various stages in the training of a radio operator. They are
applicable to whatever type of equipment is available and are numbered
according to the Unit Operation to which they apply—Tables No 7 A, B, C,
D, and E, for instance, being for use with Unit Operation No. 7, which has
for its object training the operator in two-character code groups sent at the
rate of five to seven words per minute. The instructor should read carefully
the Introduction and "Suggestions for the Instructor" which follow
immediately after each unit operation.
Because of the dissimilarity of Code Practice Equipment available at
posts, it is impracticable to indicate which Operations should be omitted.
The officer concerned with training radio operators will be obliged to
exercise his own judgment in this matter, adapting the manual to the type
of equipment at his disposal.
TRAINING MANUAL NUMBER 27
Radio Operator—Instructor's Guide for All Arms
Part II—Tactical Radio Procedure—Volume II
This manual is under revision but lack of funds will probably preclude
its printing for some time. The revision will simplify the present procedure
as laid down in this manual so that if an operator is trained in the old
procedure, he will have no difficulty in learning the new. It will be only a
question of omitting certain of the procedure which he has learned.
In using this manual, the ordinary procedure should be gone through
with, that is, the introduction should first be studied and then the
"Suggestions for the Instructor" for each unit operation before attempting
to instruct in that unit operation.
No omissions are recommended. Probably there is no other branch
of communications in which teamwork and similarity of training
between the various arms is so essential as in radio. For this reason, the
use of this manual as it is, is recommended.
