Start-Frequency Switch Settings
As described in chapter
miniRepeaters utilise a high rejection filter to allow
only the desired frequency band to be repeated. The
miniRepeaters are available in different bandwidths
with field adjustable start frequencies to support the
desired frequency band of the user.
Two rotary switches, located on the side of the
miniRepeater, are provided for setting the start
frequency (SF) of the high rejection filter. The SF of
the high rejection filter may be adjusted in either 200
or 250 kHz steps, dependent upon the miniRepeater
model.
Following are tables that show the filter band-pass
start frequencies corresponding to the switch settings.
The following section will show tables of standard
user settings.
