back-to-back as multichannel radio relay station, a different
frequency separation may be required between the receivers than the
frequency separation normally required when the receivers are located
separately at the same location.
d. At times it may be possible to use the same set of
frequencies, from a block of frequencies, more than once within a
are at the same location, providing that they are transmitted in
opposite or near opposite directions.
The effectiveness of this
method will depend on the selectivity and sensitivity of the
receivers used, and the overall distance between them.
e. Generally, the only sure way to minimize the effects of mutual
interference between transmitters and receivers is to adhere rigidly
to the applicable instructions on frequency management and selection.
These are given in the equipment's applicable technical manual. This
information will differ from one type of multichannel radio set to
with the assigned operating frequencies using the single ABM plan.
