channel grid in the range of channels S21 … C69 (frequency grid 8 MHz).
The CCIR channel grid is 7 MHz in the range of the lower frequency bands
(channels C2 … S20). Therefore the frequency setting is used here. If one uses
the existing channel grid of 7 MHz in these channel ranges, this will result in
interference (overlapping) with the 8 MHz QAM signal packages, thus caus-
ing transmission problems.
For programming in these channel ranges and in the frequency ranges below
them, we recommend starting with channel S21 / 306 MHz going back in
steps of 8 MHz (see frequency table on page 47), or reducing the bandwidth of
the QAM output signal by removing stations.
