Chelsea Yaesu DR-2X Repeater Setup

Assuming anyone globally (but within range of the repeater) had obtained the exact B-channel
repeater frequency and PL tone, he would then have as much control over the repeater as we do.
There is one additional layer of encryption that can be added. All of the remote commands have
factory assigned 4-digit integer codes. For example, the code to switch the repeater output power to
MID is 0020. All of these values are user definable. We could assign our own random numbers to
each command. The prankster would then need those codes to do anything.
PASSWORD:
At power application or after the display has timed out from programming inactivity, the display
goes blank, and a password is needed. This password does not enable operation of the repeater but
merely grants access for programming. Without this password the repeater cannot be programmed
without first restoring all of the factory settings. The password is: 0000.
Introduction
In this presentation we will start with a Yaesu DR-2X Fusion repeater (shown below) that may or may
not have some programming written into it. We are going to set it up to fulfill its role as an amateur
radio 2 meter VHF repeater which is Fusion capable. The repeater shall operate in a single-channel mode
using an uplink frequency of 144.850 MHz and a downlink frequency of 145.450 MHz. Transmit power
shall be set to MEDIUM. The FCC assigned station call sign is WD8IEL.
Program for ID and UP/Downlink
Frequencies
With power application we have the screen showing as
above in Figure 1.
Our first task will be to check on the call sign entry.
Upon power application the home screen (Figure 2) is
shown. We press the [
A SETUP
] button showing the
screen illustrated in Figure 3.
We can see that the repeater is already properly
programmed for the correct up and downlink
frequencies.
Figure 2 This is the "home" screen which appears at
power application.
