7.1.6 Radio Receiver and Transmitter module - RTX
The “Radio Receiver and Transmitter” (RTX) module is the module that realizes a full duplex
radio in the frequency bands commonly used by in the LMR/PMR market (136 - 174 MHz). It
is able to operate with channel spacing of 12.5 kHz, 20 kHz and 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 RTX module main functionalities are:
• Dynamic Dual mode radio operations with support of digital and analog modulation
• Synchronization from external reference via SYNC module
• Temperature control.
• VHF band: 136 – 174 MHz
The front panel is provided with bi-color leds to help in troubleshooting the system. The table below
describes the meaning of the leds:
