DMR repeater 24/01/2011 1 Versione 1.1 INTRODUCTION This document illustrates the applications and how to use the Radio Activity DMR base stations management software. Radio Activity DMR base stations can support a lot of applications and the management software is designed with forms for reading the parameters that can change depending on the particular application.

DMR repeater 24/01/2011 Versione 1.1 The current flowing into final amplifier transistor is continuously monitored by microcontroller to verify the correct functioning and to reveal any efficiency degradation. The module is equipped with an harmonic filter to lower spurious emissions under required levels by existing regulations. 2.
DMR repeater 24/01/2011 Versione 1.1 2.3.2 SATELLITE BASE STATION IN “RF LINKED” NETWORKS The duty of the Satellite is: ∞ receiving the signals from the terminals and sending them to the Master through the RF link, ∞ transmitting to the terminals the signals received by the Master (voted) through the RF link. The satellite performs also the group delay and absolute delay equalization on broadcasting transceivers both down link and up link. 2.
DMR repeater 24/01/2011 Versione 1.1 In this way all satellites are zeroed in frequency compared to master and then zeroed between them. If there is not a good frequency synchronization the quality of communication considerably decreases in the equal fields strenght areas. Another essential function of Radio Activity simulcast networks is the voting, which is the method by which the best signal received from the network is continuously selected.
