Frequencies -—The visual carrier frequency (channels T7-116) is shown in this chart, in MHz. For the aural carrier frequency, add 4.5 MHz to the visual carrier. The lower edge

of the channel is 1.25 MHz below the visual carrier and the upper edge is 4.75 MHz above the visual carrier.

CATV/IRC — IRC spacing is the same as standard CATV frequencies, except for Channels 5 and 6.

HRC/IRC — About 10% of CATV systems use these alternate frequency plans, created to reduce ―beat‖ interference.

FCC – U.S. Broadcast VHF/UHF

*Channel 1 — IRC/HRC spacing created a Channel 1 between 4 and 5, the rarely used channel must be shifted to different frequency for IC-Net operation
