Misuse and confusion of call signs, routing
indicators, address groups, and address
indicating groups (AIGs) (which could result in
the nondelivery of an important message, a
compromise, or the linking of classified and
unclassified call signs and address groups);
Violation of emission control (EMCON)
Unofficial conversation between operators;

Transmitting the operators personal sign;
Excessive repetition of prowords;
Use of plain language in place of applicable
Incorrect and unauthorized procedures;
Identification of unit locations;
Excessively long calls (when a station is called
and does not answer within a reasonable time,
presumably because a condition of radio silence
prevails, the message may be transmitted in the
blind or by some other method);
Use of profane, indecent, or obscene language;
Failure to maintain radio watches on designated
frequencies and at prescribed times.
You should use the following guide in developing
good voice circuit techniques. To enhance your
proficiency, you should practice the techniques on a
training net. Remember, though, that nothing can take
the place of good common sense.
Listen before transmitting. Unauthorized break-
in causes confusion and often blocks a
transmission in progress to the extent that neither
transmission gets through.
Speak clearly and distinctly. Both slurred
syllables and clipped speech are hard to
understand. A widespread error among
untrained operators is failure to emphasize
Speak slowly. Give the receiving operator a
chance to get your message down. This can save
time and repetitions.
Avoid extremes of pitch. A high-pitched voice
cuts through interference best, but is shrill and
unpleasant if too high. A lower pitch is easier on
the ear, but is difficult to understand through
background noises if too low.
Be natural. Maintain a normal speaking rhythm.
Group words in a natural manner. Send your
message phrase for phrase instead of word for
Use standard pronunciation. Talkers who use the
almost standard pronunciation of a broadcast
network announcer are easiest to understand.
Speak in a moderately strong voice in order to
override unavoidable background noises and to
Keep correct distance between lips and handset.
A distance of about 2 inches is correct for most
handsets. If the distance is too great, speech
becomes inaudible and background noises
interfere. If the distance is too small, blaring and
Give an accurate evaluation in response to a
request for a radio check. A transmission with
feedback or a high level of background noise is
not loud and clear, even though the message
can be understood.
Pause momentarily after each normal phrase,
and interrupt your carrier. This allows any other
station with higher precedence traffic to break in.
