G1B07
What are the restrictions on the use of abbreviations or procedural signals in the amateur service?
Pick an answer to check it.
Answer: B. They may be used if they do not obscure the meaning of a message
Abbreviations and procedural signals are allowed as long as they do not obscure the meaning of a message. Using them to hide meaning would be like using a code, which is not permitted.
Tip: Abbreviations OK, hidden meanings not.
