Why should you keep transmissions short when using a repeater?

Repeaters are shared community resources used to extend communication range. Keeping your transmissions short ensures that the frequency remains accessible to other operators, particularly if someone needs to break in with an emergency call. Additionally, most repeaters are equipped with a time-out timer (typically set to a few minutes) that will automatically cut off the signal if a transmission lasts too long. This safety feature prevents a stuck microphone from completely tying up the system. Distractors such as long-distance charges or memory storage are incorrect because standard amateur repeaters do not bill for airtime and typically do not store voice data. Bandwidth is determined by the modulation type, not the duration of the transmission.
