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:DuplexersPower SupplyAntennasWindow 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 Simplex or Duplex frequencyMyCall Your call sign (primary operator)UrCall Call sign of the person / zone being calledRpt1 1st repeaterRpt2 2nd repeater
Understanding how it works (Simplex)To complete a local simplex call, program 2 fields along with the
frequency in the radio.
MyCall My call sign (eg. W7JRL)UrCall Your call sign or “CQCQCQ”

Understanding how it works (Simplex)In this example, all parties in digital mode hear all the traffic on the
simplex channel.

D-STAR
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 Simplex or Duplex frequencyMyCall Your call sign (primary operator)UrCall Call sign of the person / zone being calledRpt1 1st repeaterRpt2 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 My call sign (eg. W7JRL)UrCall Your call sign or “CQCQCQ”Rpt1 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 W7JRLRPT1 N7IH AUrCall CQCQCQRPT2 nothing
N7IH Repeater
Understanding how it works (Repeater)Eg. MyCall W7JRL
RPT1 N7IH AUrCall CQCQCQRPT2 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.
MyCall - N9JA
UrCall – CQCQCQ
Rpt1 – N7IH A
MyCall – W7JRL
UrCall – CQCQCQ
Rpt1 – N7IH A
Repeater – N7IH
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 My call sign (eg. W7JRL)UrCall Your call sign or “/ zone” and module (eg. /K5TIT A)Rpt1 Local repeater call signRpt2 Local repeater + “G” as the 8th letter (eg. N7IH G)
Understanding how it works (Repeater)Eg. MyCall W7JRL
RPT1 N7IH AUrCall /K5TITRPT2 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 W7JRL
RPT1 N7IH AUrCall /K5TITRPT2 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 W7JRL
RPT1 N7IH AUrCall /K5TITRPT2 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.
MyCall – W7JRL
UrCall – /K5TIT
Rpt1 – N7IH
Rpt2 – N7IH G
Repeater – N7IH Repeater – K5TIT
MyCall - N9JA
UrCall – /N7IH
Rpt1 – K5TIT
Rpt2 – K5TIT G
Gateway / Internet
Understanding how it works (Repeater)Eg. MyCall W7JRL
RPT1 N7IH AUrCall /K5TIT ?RPT2 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 W7JRL
RPT1 N7IH AUrCall /K5TIT CRPT2 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 W7JRL
RPT1 N7IH AUrCall /K5TITRPT2 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 W7JRL
RPT1 N7IH AUrCall N9JARPT2 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.
MyCall – W7JRL
UrCall – N9JA
Rpt1 – N7IH A
Rpt2 – N7IH G
Repeater – N7IH Repeater – W1AW
MyCall - N9JA
UrCall – W7JRL
Rpt1 – W1AW A
Rpt2 – W1AW G
Gateway / Internet
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.
MyCall – W7JRL
UrCall – /W1AW A
Rpt1 – N7IH A
Rpt2 – N7IH G
Repeater – N7IH Repeater – W1AW
MyCall - N9JA
UrCall – /N7IH A
Rpt1 – W1AW A
Rpt2 – W1AW G
Gateway / Internet
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.
MyCall – W7JRL
UrCall – /W1AW A
Rpt1 – N7IH A
Rpt2 – N7IH G
Repeater – N7IH Repeater – W1AW
MyCall - N9JA
UrCall – /N7IH A
Rpt1 – W1AW A
Rpt2 – W1AW G
Gateway / Internet
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.
MyCall – W7JRL
UrCall – /W1AW A
Rpt1 – N7IH A
Rpt2 – N7IH G
Repeater – N7IH Repeater – W1AW
MyCall - N9JA
UrCall – /N7IH A
Rpt1 – W1AW A
Rpt2 – none
Gateway / Internet
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 My call sign (eg. W7JRL)UrCall Your call sign or “CQCQCQ”Rpt1 Local repeater input module call sign (eg. N7IH A)Rpt2 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 W7JRL
RPT1 N7IH AUrCall CQCQCQRPT2 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.
MyCall - N9JA
UrCall – CQCQCQ
Rpt1 – N7IH C (440 MHz)
Rpt2 – N7IH A
MyCall – W7JRL
UrCall – CQCQCQ
Rpt1 – N7IH A (1.2 GHz)
Rpt2 – N7IH C
Repeater – N7IH
Understanding how it works (Repeater)
In this example, W7JRL would not hear N9JA reply because he is not properly programmed for cross-band operation.
MyCall - N9JA
UrCall – CQCQCQ
Rpt1 – N7IH C (440 MHz)
Rpt2 – none
MyCall – W7JRL
UrCall – CQCQCQ
Rpt1 – N7IH A (1.2 GHz)
Rpt2 – N7IH C
Repeater – N7IH
