D-STAR How it works

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.
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
In this example, all parties in digital mode hear all the traffic on the simplex channel.
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
When you program your radios 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
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

All parties on the local repeater channel will hear all the local radio traffic on that frequency.
Repeater N7IH MyCall W7JRL UrCall CQCQCQ Rpt1 N7IH A MyCall - N9JA UrCall CQCQCQ 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)
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
routed to the gateway and directed to the proper remote repeater through the internet.
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
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 Rpt1 K5TIT Rpt2 K5TIT G
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

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.
Currently, you are not able to activate more than 1 module at the remote repeater site.
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
Using the call sign of the desired party to be reached in the UrCall field automatically routes to wherever the radio was last heard.
Repeater N7IH MyCall W7JRL UrCall N9JA Rpt1 N7IH A Rpt2 N7IH G
Repeater W1AW MyCall - N9JA UrCall W7JRL Rpt1 W1AW A Rpt2 W1AW G
In both examples, all parties on the local repeater and remote repeater hear all the radio traffic on the frequency.
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
Both radios must be properly programmed to operate via the gateway in order for transmissions to be heard both directions.
In this example, N9JA would hear W7JRLs transmission but, W7JRL would not hear N9JA since no gateway is selected.
Repeater W1AW MyCall - N9JA UrCall /N7IH A Rpt1 W1AW A Rpt2 none
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.
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.
In this example, all parties listening on 1.2GHz and 440MHz would hear all radio traffic.
Repeater N7IH MyCall W7JRL UrCall CQCQCQ Rpt1 N7IH A (1.2 GHz) Rpt2 N7IH C MyCall - N9JA UrCall CQCQCQ Rpt1 N7IH C (440 MHz) Rpt2 N7IH A
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 Rpt1 N7IH A (1.2 GHz) Rpt2 N7IH C MyCall - N9JA UrCall CQCQCQ Rpt1 N7IH C (440 MHz) Rpt2 none
