Which of the following is required when making on-the-air test transmissions?
The correct answer is A: Identify the transmitting station. According to FCC Part 97.119, when making on-the-air test transmissions, you must identify your station with your call sign. This requirement applies to all transmissions, including test transmissions.
Test transmissions are allowed for checking equipment, antennas, or propagation, but they're not exempt from identification requirements. You must identify your station just as you would during normal communications. There's no requirement to conduct tests only at certain times or to notify the FCC of routine test transmissions.
Exam Tip
Test transmissions = Must identify. Remember: Even during test transmissions, you must identify your station with your call sign. There are no time restrictions or FCC notification requirements.
Memory Aid
"**T**est **T**ransmission = **T**ransmit **I**D (think 'TT = TI' = Transmit ID)"
Real-World Application
You're testing your new antenna and want to make a brief transmission to check SWR and signal strength. You key up and say 'Kilo Alpha One Bravo Charlie, testing' or send your call sign in Morse code. This identifies your station during the test transmission, which is required even for brief equipment tests.

Why Other Options Are Wrong
Option B: Incorrect. There's no restriction on when you can make test transmissions. You can test your equipment at any time, as long as you identify your station.
Option C: Incorrect. You don't need to notify the FCC of routine test transmissions. Only identification is required.
Option D: Incorrect. Not all options are correct. Only station identification is required for test transmissions.
