If you fit in the "new" transponder to an existing antenna plant, you have to
set the output frequency
to a unused channel
.
—> The output signal is normally transmitted with a bandwidth of 8
MHz. This means that you can only use the channel centre frequen-
cy of the existing channel 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 (channels C5 … C12). If 8
MHz 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 rang-
es below them, we recommend starting with frequency 306 MHz
going back in steps of 8 MHz (see frequency table on page 41).
Please note thereby that a few older receivers cannot receive the
channel ranges S21 … S41 (306 … 466 MHz).
