Squelch indicator
This circuit uses a dual LED, green and red, common catode.

When the radio is turned ON, the green LED will light.
When a signal is received, the squelch will open, and the red LED lights too.
This gives an orange colour.

A single LED can be used instead, to give the open-squelch-info only.
