Kenwood NX-5200K3 Common Function Reference

Examples of Mobile Relay Station Operation
The following examples of the operation describes the behavior in a P25 Conventional system, but ID, frequency, and
Signaling (QT/DQT, RAN) are transferred by the same the behavior in Analog Conventional and NXDN Conventional
systems.
Also,
all functions of each Conventional system, such as Optional Signaling (DTMF, 2-tone, MDC-1200, FleetSync, NXDN
ID), Encryption, Emergency, and the functions of various calls, can be used.
Operation example 1
This is the example of the operation if Mobile Relay Station is used with the UHF transceiver as the transmitting unit and
the VHF transceiver as the receiving unit in a P25 Conventional system.
The channel configurations of RF Deck 1 and RF Deck 2 are as follows:

Talkgroup ID = B
RX Frequency = 145.5 MHz
NAC Dec = 29C
Source Unit ID = A
Talkgroup ID = B (Unit ID = A)
TX Freq = 145.5 MHz (RF Deck 2)

In this case, RF Deck 1 behaves as the receiving repeater and RF Deck 2 behaves as the transmitting repeater.
Contrary
to the example shown above, RF Deck 2 can behave as the receiving repeater and RF Deck 1 can behave as the
transmitting repeater.
