of the air tour radio frequencies over Grand Canyon has recently
been changed. The eastern sector of the Canyon, from Lees Ferry
to Havasu/Kanab Creek has changed from 122.85 to 120.05. This is
now the frequency that a person would use to contact an overflight
of a tour plane/helicopter in Marble Canyon, lcr, and central section
of the gorge (Phantom Ranch, Crystal, etc.). Of course, 121.5 is
still the "emergency" frequency.
This change was due to conflicts that had arisen due
to different uses of frequencies too close together, and has been
in the works for about 2 years.
Be aware that the current regulations still show the
old frequencies. Once new ones are printed and distributed with
new permits, the change will show.
