BANDWIDTH FILTER SETTINGS
The TX3500S is fitted with two user-selectable receiver
bandwidth filters which allow the receiver to be adjusted for
either wide or narrow band reception on channels 1 – 40.
This feature provides additional compatibility with older
40-channel radios. The wide setting increases the tolerance
of the TX3500S receiver to older wideband 40 channel radios
or to signals that might be slightly off frequency. The narrow
setting increases the selectivity of the receiver to help reduce
interference from strong interfering signals on adjacent
channels.

Band Filter. The close spacing of the signal meter bars
