Q

ID the rules
for radio
discipline

A

1.Use correct voice procedure
2.Maintain a constant listening radio watch unless specific instructions or
permission has been received to the contrary
3. Ensure that the correct frequency is in use
4. Answer calls in the correct order and without delay
5. Listen carefully before transmitting to ensure that the frequency is clear and, where possible allow for stations which cannot be heard
6. Release the pressel switch promptly
7.On releasing the pressel switch, ensure that the radio returns to the receive
condition

Always:
1. Violate radio silence
2. Compromise classified information by unauthorized plain language disclosure
3. Make unnecessary or unduly long transmissions
4. Engage in unofficial conversation or operator’s chat
5. Identify an individual, ship or unit by name, or any other personal or individual
sign
6. Speak faster than the station experiencing the worst reception conditions can be
expected to receive, thus avoiding needless repetition
7. Show loss of temper or resort to profane language
