VHF DIGITAL RF MODULE
Digital Voice + Digital Data
IMAGINE a world where you can get a VHF and UHF repeater pair! Or when VHF and UHF DX does
not require a band opening! Or even a plug and play repeater system that gives you functionality
and capabilities that no other radio service in the world can offer! This dream has become a reality
with the introduction of Icom’s ID-RP2000V and ID-RP4000V D-STAR Modules.
Whether you are a repeater owner wanting to experiment in the digital world or a club who who wants
more from their repeater network, D-STAR is defi nitely the future of Amateur Radio.

The power of D-STAR offers
fl exibility and system growth!
RP2C: With the capability of handling
up to four RF modules, the ID-RP2C repeater
controller is the cornerstone of the
D-STAR repeater system. This includes
basic in-band as well as crossband operation
between any of the four digital voice
RF modules. In addition to basic control
of the RF modules, the RP2C also provides
linking capabilities through the internet
and future 10GHz backbone products.
RP2D: (23cm Data)
One of the most powerful functions of DSTAR
is the ability to move data. The IDRP2D
provides an access point with a data
rate of 128kbps. Depending on the system
setup, the 128kbps is perfect for setting up
an email and/or fi le server for EmComm support.
It’s also perfect for connecting to the
internet for web applications or support.
Whether you use the 128kbps for email
or fi le servers, connecting to an internet
source via a router will give you the capability
of checking out the radar from the
National Weather Service or National Hurricane
Digital Voice: No room for another
repeater pair? No problem for the Icom DSTAR
repeaters! In addition to the 128kbps
data, D-STAR incorporates the power of
digital voice and 1kbps data mode on 2m,
70cm, and 23cm. The spectral effi ciency,
crystal clarity, and the ability of repeating
data and voice communications on a
single 6.25 kHz channel is something yet
to be seen in any other radio service! With
this capability, we can expand the number
of repeaters available in your area.
ICOM’s D-STAR compatible repeaters modules:
RP2V: (23cm) RP4000V: (70cm) RP2000V: (2m)
Crossband Operation: Finally, a commercially available legal
crossband repeater! With proper callsign programming in any D-STAR
compatible mobile or portable, the Icom D-STAR repeaters will automatically
route your signal to any other RF module connected to a common
RP2. With simple repeater commands, you can direct your communications
through any of the RF modules.
Repeater Confi guration:
There are three distinct repeater confi gurations currently available.
Local: This confi guration is very similar to most analog repeater systems without any linking or
internet requirements or capabilities, and is primarily used for Digital Voice and 1kbps operations.
Local with Internet: Expand to the local repeater with the addition of the ID-RP2D and a
simple DSL connection through a router. While this allows internet connectivity with an ID-1, there
is no control over who is able to use the internet connection. (Interconnection with other remote
users is not possible.)
Gateway: This is the ultimate D-STAR confi guration providing a controlled internet connection
as well as linking to other repeaters installed into a common D-STAR network. All users of the DV
(digital voice) gateway of 128kbps internet connection must be registered in one of the D-STAR
networked repeaters. ( NOTE: A static IP address is required to set up a gateway D-STAR repeater.
A few examples of a gateway network can be seen on www.dstarusers.org website.)
Applications and Uses
1kbps: The 1kbps is the transport
layer for your data communications using
the serial port of your computer. While
considered a slow data rate, the 1kbps
can move a considerable amount of data
and co-exist on the same frequency with
PC: (Applications pending) An exciting
new area to experiment, each of the ICOM
D-STAR compatible radios utilizes a serial
port interface for 1kbps. So, any fi les,
messages or data you send through the
serial port or USB port on your laptop will
move through the D-STAR network.
PDA: (Applications pending) Communicate
with others via text through the serial
port on your PDA. Complete forms and
send them from in the fi eld, or just a quick
text message to say hello. This is a perfect
combination for the Amateur on the go!
GPS: Connect any NMEA compatible
GPS to the serial port of the Icom D-STAR
compatible radios and send GPS coordinates,
either with each press of the PTT
button or at preset TX intervals.
Gateway Communications: Expand your VHF, UHF, and SHF horizons by adding the D-STAR gateway. The Gateway operates like a router, directing your communications
either locally or over the internet based on the callsigns used. There are four callsigns used in routing calls over a D-STAR repeater. The most critical is the “My”
or “Mycall” as it identifi es the originating communication. There are two repeater callsign locations as well as a destination callsign, “Your” or “Urcall”. The tables below show
proper programming of these callsign locations.

|Module|| Band|| Mode
| A || 23cm || DV
| A || 23cm ||DD
| B || 70cm|| DV
| C || 2m || DV
Local communications (User radio)
Note: Each callsign location can hold up to eight characters. The 8th character is the “Switch” and is necessary for controlling the repeater.
Spaces are required to position the switch character into the 8th character location.
