The fixed-tune guard receiver at 243.000 MHz serves what purpose?

Explanation:
A fixed-tune guard receiver at 243.000 MHz is an always-on monitor for the guard (emergency) channel. This dedicated receiver provides a continuous watch on a emergency-use frequency so distress calls or urgent communications can be received regardless of the main operating channels. It’s specifically for emergencies, not for normal data links, navigation beacons, or voice retransmission.
