Basic System
What’s required?
Repeater Call Sign
First, you need is a unique / club call for the repeater.
* You can not have the same call sign in 2 different “roles” in the D-STAR
network. (eg, the repeater call sign can not also be your individual call sign.)
You will need a unique / club call sign for your repeater system that is not
used anywhere else in the network.
What’s required?
Repeater Components
Next, you need the desired repeater modules. The RP2C is REQUIRED
for the D-STAR repeater system.
The current D-STAR repeater modules are:
RP2D
1.2GHz, 128K Digital Data (DD)
RP2V
1.2GHz Digital Voice (DV)
RP4000V
440MHz Digital Voice (DV)
RP2000V
144MHz Digital Voice (DV)
What’s required?
Additional hardware
Each physical install is different. What your install requires may vary.
Examples of additional equipment:
Duplexers
Power Supply
Antennas
Window Filter
D-STAR
How it works Part 1
Understanding how it works
D-STAR utilizes call signs to “route” the radio call.
Every repeater must be assigned a unique call sign (club call
recommended).
Every owner / operator programs their radio with their own call sign.
Call sign is transmitted digitally with each transmission.
No need to voice ID with D-STAR since digital ID is part of each TX.
Understanding how it works
Each radio has 4 call sign fields to be programmed. What you need to
know to program a radio is:
Operating frequency
MyCall
UrCall
Rpt1
Rpt2
Simplex or Duplex frequency
Your call sign (primary operator)
Call sign of the person / zone being called
1st repeater
2nd repeater
Understanding how it works (Simplex)
To complete a local simplex call, program 2 fields along with the
frequency in the radio.
MyCall
UrCall
My call sign (eg. W7JRL)
Your call sign or “CQCQCQ”
MyCall - W7JRL
UrCall – CQCQCQ
MyCall - N9JA
UrCall – KD7DIQ
MyCall - KD7DIQ
UrCall – CQCQCQ
Understanding how it works (Simplex)
In this example, all parties in digital mode hear all the traffic on the
simplex channel.

How it works Part2
Understanding how it works
D-STAR utilizes call signs to “route” the radio call.
Every repeater must be assigned a unique call sign (club call
recommended).
Every owner / operator programs their radio with their own call sign.
Call sign is transmitted digitally with each transmission.
No need to voice ID with D-STAR since digital ID is part of each TX.
Understanding how it works
Each radio has 4 call sign fields to be programmed. What you need to
know to program a radio is:
Operating frequency
MyCall
UrCall
Rpt1
Rpt2
Simplex or Duplex frequency
Your call sign (primary operator)
Call sign of the person / zone being called
1st repeater
2nd repeater
Understanding how it works (Repeater)
To complete a local zone repeater call, program 3 fields along with the
frequency in the radio.
MyCall
UrCall
Rpt1
My call sign (eg. W7JRL)
Your call sign or “CQCQCQ”
Local repeater call sign
Understanding how it works (Repeater)
When you program your radio’s
“RP1” location, and the proper
frequency, your radio tells the
desired repeater to activate.
This is similar to PL tones in
analog.
Eg. MyCall
RPT1
UrCall
RPT2
W7JRL
N7IH A
CQCQCQ
nothing
N7IH Repeater
Understanding how it works (Repeater)
Eg. MyCall
RPT1
UrCall
RPT2
W7JRL
N7IH A
CQCQCQ
nothing
In this example, the N7IH repeater
would activate on the repeater
frequency you were
transmitting on (1.2GHz).
(In this example, we are using the ID-1
radio.)
N7IH Repeater
Understanding how it works (Repeater)
All parties on the local repeater channel will hear all the local radio
traffic on that frequency.
Repeater – N7IH
MyCall – W7JRL
UrCall – CQCQCQ
MyCall - N9JA
UrCall – CQCQCQ
Rpt1 – N7IH A
Rpt1 – N7IH A
Understanding how it works (Gateway)
To complete a gateway repeater call, program all 4 call sign fields within
the radio.
Repeater must be connected to a gateway server PC.
MyCall
UrCall
Rpt1
Rpt2
My call sign (eg. W7JRL)
Your call sign or “/ zone” and module (eg. /K5TIT A)
Local repeater call sign
Local repeater + “G” as the 8th letter (eg. N7IH G)
Understanding how it works (Repeater)
Eg. MyCall
RPT1
UrCall
RPT2
W7JRL
N7IH A
/K5TIT
N7IH G
In this example, the N7IH repeater
would activate on the repeater
frequency you were
transmitting (1.2GHz) and
then…
(In this example, we are using the ID-1
radio.)
N7IH Repeater
Understanding how it works (Repeater)
Eg. MyCall
RPT1
UrCall

N7IH A
/K5TIT
N7IH G
routed to the gateway and directed
to the proper remote repeater
through the internet.
N7IH Repeater
Understanding how it works (Repeater)
Eg. MyCall
RPT1
UrCall
RPT2
W7JRL
N7IH A
/K5TIT
N7IH G
The gateway is told where to route
the call based on what is in the
“UrCall” field of the radio.
/K5TIT tells the gateway to route
the call to the K5TIT repeater.
The “/” means “zone call”.
N7IH Repeater
Understanding how it works (Gateway)
Using “/” in front of the repeater call sign in the “UrCall” field activates
that “zone” (module) at the remote repeater.
Gateway / Internet
Repeater – N7IH
MyCall – W7JRL
UrCall – /K5TIT
Rpt1 – N7IH
Rpt2 – N7IH G
Repeater – K5TIT
MyCall - N9JA
UrCall – /N7IH

Rpt2 – K5TIT G
Understanding how it works (Repeater)
Eg. MyCall
RPT1
UrCall
RPT2
W7JRL
N7IH A
/K5TIT ?
N7IH G
Since we did not designate a
“module” in the “UrCall” field,
the system automatically
routes to the “A” module of the
remote repeater (K5TIT).
K5TIT Repeater
Understanding how it works (Repeater)
Eg. MyCall
RPT1
UrCall
RPT2
W7JRL
N7IH A
/K5TIT C
N7IH G
If we add the “designator” as the 8th
letter, we can route to different
modules at the remote
repeater site.
K5TIT Repeater
Understanding how it works (Repeater)
Eg. MyCall
RPT1
UrCall
RPT2
W7JRL
N7IH A
/K5TIT
N7IH G
Currently, you are not able to
activate more than 1 module at
the remote repeater site.
K5TIT Repeater
Understanding how it works (Repeater)
Eg. MyCall
RPT1
UrCall
RPT2
W7JRL
N7IH A
N9JA
N7IH G
If you use the call sign of the
person you wish to call, the
gateway automatically routes
the call to the last known
location of that call sign within
the repeater network.
N7IH Repeater
Understanding how it works (Gateway)
Using the call sign of the desired party to be reached in the “UrCall”
field automatically routes to wherever the radio was last heard.
Gateway / Internet
Repeater – N7IH
MyCall – W7JRL
UrCall – N9JA
Rpt1 – N7IH A
Rpt2 – N7IH G
Repeater – W1AW
MyCall - N9JA
UrCall – W7JRL
Rpt1 – W1AW A
Rpt2 – W1AW G
Understanding how it works (Gateway)
In both examples, all parties on the local repeater and remote repeater
hear all the radio traffic on the frequency.
Gateway / Internet
Repeater – N7IH
MyCall – W7JRL
UrCall – /W1AW A
Rpt1 – N7IH A
Rpt2 – N7IH G
Repeater – W1AW
MyCall - N9JA
UrCall – /N7IH A
Rpt1 – W1AW A
Rpt2 – W1AW G
Understanding how it works (Gateway)
Both radios must be properly programmed to operate via the gateway in
order for transmissions to be heard both directions.
Gateway / Internet
Repeater – N7IH
MyCall – W7JRL
UrCall – /W1AW A
Rpt1 – N7IH A
Rpt2 – N7IH G
Repeater – W1AW
MyCall - N9JA
UrCall – /N7IH A
Rpt1 – W1AW A
Rpt2 – W1AW G
Understanding how it works (Gateway)
In this example, N9JA would hear W7JRL’s transmission but, W7JRL
would not hear N9JA since no gateway is selected.
Gateway / Internet
Repeater – N7IH
MyCall – W7JRL
UrCall – /W1AW A
Rpt1 – N7IH A
Rpt2 – N7IH G
Repeater – W1AW
MyCall - N9JA
UrCall – /N7IH A
Rpt1 – W1AW A
Rpt2 – none
Understanding how it works (Repeater)
To complete a cross-band (cross-module) repeater call, program all 4
call sign fields within the radio. Repeater must have multiple voice
modules installed.
MyCall
UrCall
Rpt1
Rpt2
My call sign (eg. W7JRL)
Your call sign or “CQCQCQ”
Local repeater input module call sign (eg. N7IH A)
Local repeater output module as the 8th letter (eg. N7IH C)
Signal is repeated on both input and output frequencies / modules locally.
Understanding how it works (Repeater)
Eg. MyCall
RPT1
UrCall
RPT2
W7JRL
N7IH A
CQCQCQ
N7IH C
When using the designator of
another local module in the
“RPT2” field, the call is routed
to that module locally.
N7IH Repeater
Understanding how it works (Repeater)
In this example, all parties listening on 1.2GHz and 440MHz would hear
all radio traffic.
Repeater – N7IH
MyCall – W7JRL
UrCall – CQCQCQ
MyCall - N9JA
UrCall – CQCQCQ
Rpt1 – N7IH A (1.2 GHz)
Rpt2 – N7IH C
Rpt1 – N7IH C (440 MHz)
Rpt2 – N7IH A
Understanding how it works (Repeater)
In this example, W7JRL would not hear N9JA reply because he is not
properly programmed for cross-band operation.
Repeater – N7IH
MyCall – W7JRL
UrCall – CQCQCQ
MyCall - N9JA
