The fixed-tuned guard receiver in the UHF Command Radio Set is set to which frequency?

Explanation:
A guard channel is a dedicated listening frequency kept on at all times so distress calls or priority traffic can be heard even when you’re using other frequencies. In the UHF Command Radio Set, this fixed-tuned guard receiver is on 243.000 MHz because that is the standard UHF military guard frequency used for emergency and command communications. It provides a reliable, universal channel for reaching or hearing other units when normal channels are busy or unusable. The civilian emergency frequency 121.5 MHz is not the military guard channel, and the other options are not designated guard frequencies for this UHF set.
