This section explains how often and when you must give your call sign. Many hams are confused by some of the wording in this regulation. For instance, some operators believe they must say their call sign at the end of every transmission. Another misinterpretation is the operator that feels he must say his call sign every ten minutes even though he has not spoken during that time, such as when monitoring a frequency or listening to a net on a repeater.

Q: Do I have to say my call sign every ten minutes on a repeater I am monitoring?A: No. If you are just listening then you do not have to identify your station. Operators wanting to make their availability to chat known to other repeater listeners will state their call sign in conjunction with the term "monitoring." You are required to state your call sign if you are going to transmit, within 10 minutes of the first transmission. Subsequently while you listen and wait for a response you do not have to continue to identify your station every ten minutes since you are no longer transmitting. However, you increase the probability of a contact if you continue to identify your station on the repeater from time to time, and every ten minutes would not be excessive.
