Contemporary Research 11 QMOD-HD Integration
When the channels for over-the-air TV were created, the FCC had to carve out gaps to avoid
conflicts with frequencies that were already assigned. As a result, as you move from Channel 2
upwards, the frequencies jump around a bit. As the easy architecture for creating your own HD
cable system is to stay in the low frequencies, it’s important to keep this in mind.

Frequencies are shown at the center-channel values. Digital channels are measured at the center;
analog channels are measured close to the start of each 6 MHz channel, 1.75 MHz from the center
Channels 99-99 are in the FM band, there may be interference if a FM station antenna is nearby
