Section 2. Frequencies

1. VOR AND VORTAC VOICE CHANNELS

Provide control lines for air-ground communications and Category I monitoring on all VORs and VORTACs as follows:

1. Provide independent transmitting and receiving lines to the controlling FSS when a remote communications outlet is associated with the VOR or the VORTAC.
2. Provide one line when a remote communications outlet has only a 122.1 MHz receiver.
3. Control lines are not required if line costs considerably exceed normal costs and cannot be justified in a particular case.
