(Refer to FAA-CT-8080-2H, Figure 22, area 2.) At Coeur D'Alene which frequency should be used as a Common Traffic Advisory Frequency (CTAF) to monitor airport traffic?

Explanation

In Figure 22 the Coeur d'Alene-Boyington (COE) airport data block reads '2320 *L 74 122.8 (C)'; the frequency followed by the C symbol is the CTAF, 122.8 MHz (AIM 4-1-9). 135.075 MHz is the AWOS-3 weather broadcast frequency, and 122.05 MHz is a Flight Service frequency shown on the Coeur d'Alene VOR-DME box.
