T2B02 [A] [97.119(a)]
What is a transmission called that does not contain a station identification?
A. Unidentified communications or signals
B. Reluctance modulation [ I am reluctant to even comment on this, but will say that it is wrong]
C. Test emission [Test transmissions must also be identified]
D. Intentional interference [ If no one else is using the frequency, it would not be interference - however any transmission must be identified with a station callsign ]
Discussion: In normal practice, a station identifies itself at the first transmission in a session, and the last, and every 10 minutes in between. Thus, if you are having a conversation, you do not always have to send your callsign with each press of the transmit button. Just as in a normal conversation, we call each other by name, or sometimes name & location when there are multiple people of the same name. Sometimes we use name and the last part of the callsign, such as Jim in Antioch, or Jim FWW.
