8.1.4 Double Radio Receiver module – RRX
The “Double Radio Receiver” (RRX) module module realizes a full duplex radio that work in
the following frequency band commonly used in the LMR/PMR market: 896 ÷ 912 MHz.
It is able to operate with channel spacing of 12.5 kHz, 20/25 kHz.
Limitation on usable RF bands and channel spacing may apply due to local regulations.
This module is equipped with devices for numerical computation (DSP, FPGA) and control
(microprocessor) combined with the radio receiver front-end and the transmitter driver.
The RRX module main functionalities are:
 Synchronization from external reference via CORE Master module
 Temperature control.
 Space Diversity
The front panel is provided with bi-color leds to help in troubleshooting the system. The table below
describes the meaning of the leds:
