Whats 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.
8
Whats 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)

D-STAR How it works Part 1
11

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.
12

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
frequency MyCall Your call sign (primary
operator) UrCall Call sign of the person / zone
being called Rpt1 1st repeater Rpt2 2nd
repeater
13

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
MyCall - W7JRL UrCall CQCQCQ
MyCall - N9JA UrCall KD7DIQ
MyCall - KD7DIQ UrCall CQCQCQ
14

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
52
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.
53
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
frequency MyCall Your call sign (primary
operator) UrCall Call sign of the person / zone
being called Rpt1 1st repeater Rpt2 2nd
repeater
54
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
55
Understanding how it works (Repeater)
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 W7JRL RPT1 N7IH
A UrCall CQCQCQ RPT2 nothing
N7IH Repeater
56
Understanding how it works (Repeater)
Eg. MyCall W7JRL RPT1 N7IH A UrCall CQCQCQ RP
T2 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
57
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 - N9JA UrCall CQCQCQ Rpt1 N7IH A
MyCall W7JRL UrCall CQCQCQ Rpt1 N7IH A
58
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 sign Rpt2 Local
repeater G as the 8th letter (eg. N7IH G)
59
Understanding how it works (Repeater)
Eg. MyCall W7JRL RPT1 N7IH A UrCall /K5TIT RP
T2 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
60
Understanding how it works (Repeater)
Eg. MyCall W7JRL RPT1 N7IH A UrCall /K5TIT RP
T2 N7IH G routed to the gateway and directed
to the proper remote repeater through the
internet.
N7IH Repeater
61
Understanding how it works (Repeater)
Eg. MyCall W7JRL RPT1 N7IH A UrCall /K5TIT RP
T2 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
62
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.

63
Understanding how it works (Repeater)
Eg. MyCall W7JRL RPT1 N7IH A UrCall /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
64
Understanding how it works (Repeater)
Eg. MyCall W7JRL RPT1 N7IH A UrCall /K5TIT
C RPT2 N7IH G If we add the designator as
the 8th letter, we can route to different modules
at the remote repeater site.
K5TIT Repeater
65
Understanding how it works (Repeater)
Eg. MyCall W7JRL RPT1 N7IH A UrCall /K5TIT RP
T2 N7IH G Currently, you are not able to
activate more than 1 module at the remote
repeater site.
K5TIT Repeater
66
Understanding how it works (Repeater)
Eg. MyCall W7JRL RPT1 N7IH A UrCall N9JA RPT2
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
67
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.

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.

In this example, N9JA would hear W7JRLs

no gateway is selected.

71
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.
72
Understanding how it works (Repeater)
Eg. MyCall W7JRL RPT1 N7IH A UrCall CQCQCQ RP
T2 N7IH C When using the designator of another
local module in the RPT2 field, the call is
routed to that module locally.

Understanding how it works (Repeater)
In this example, all parties listening on 1.2GHz

MyCall W7JRL UrCall CQCQCQ Rpt1 N7IH A

74
Understanding how it works (Repeater)
In this example, W7JRL would not hear N9JA reply
because he is not properly programmed for
cross-band operation.
