What does the scanning function of an FM transceiver do?
Checks incoming signal deviation
Prevents interference to nearby repeaters
Tunes through a range of frequencies to check for activity✓پاسخ درست
Tunes through a range of frequencies to determine the antenna’s resonant frequency
توضیح
Scanning steps the receiver automatically through a range of frequencies or a set of memory channels and stops when it finds a signal, so the operator can find activity without tuning by hand. It does not measure deviation or antenna resonance.
