In this menu, you can select the channel or frequen cy setting for the adjustment
of the RF output. The channel setting covers the range of channels C5 … C12
and C21 … C69, the frequency setting covers the range from 42.0 MHz to
860.0 MHz.
The COFDM signal is normally transmitted with a bandwidth of 8 MHz. This
means that you can only use the channel centre frequency of the existing chan-
nel grid in the range of channels C21 … C69 (frequency grid 8 MHz). The
CCIR channel grid is 7 MHz in the range of the lower frequency bands (chan-
nels C5 … C12). If 8 MHz COFDM signal packages are transmitted in these
channel ranges, this will result in interference (overlapping) and transmission
problems.
For programming in these channel ranges and in the frequency ranges below
them, we recommend starting with frequency 306 MHz going back in steps
of 8 MHz (see frequency table on page 47). Please note thereby that many
receivers cannot receive the channel ranges S21 … S41 (306 … 466 MHz).
