What is the UHF fixed-tuned guard receiver frequency?

Explanation:
A fixed-tuned guard receiver is designed to listen continuously on a dedicated emergency channel so you won’t miss distress calls. For UHF, that standard emergency (guard) frequency is 243.0 MHz, so the guard receiver is fixed to 243.000 MHz. This setup provides a reliable, constant watch on the distress channel regardless of what other frequencies you’re monitoring. The other frequencies listed are not the standard UHF guard channel, so they aren’t used for this purpose.
