E.2.5 Community Repeater Panel Settings
The input and output levels should be adjusted per the community repeater panel’s instructions. The
summary below gives a brief overview of the high level characteristics and community repeater
panel settings for configuration with the MTR3000 Base Station/Repeater.
E.2.5.1 Discriminator
The MTR3000 Base Station/Repeater’s Receiver audio will yield 330mV rms into 50 kΩ with an RF
input signal deviating at 60% RSD. With the community repeater panel’s own loading impedance,
the “Discriminator” signal delivered to the community repeater panel is at a high enough drive level to
leave the community repeater panel’s “Rx Audio Gain High/Low” switch in the factory default position
(back panel Switch 1).
E.2.5.2 Tx Audio
The MTR3000 Base Station/Repeater’s transmitter will yield 60% RSD with 80mV rms into the Emph
Tx Audio port. The “Tx Audio” signal delivered by the community repeater panel is at a high enough
drive level to leave the community repeater panel’s “Tx Audio Gain High/Low” switch in the factory
default position (back panel Switch 4).
