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.

RF Modules:
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 Center.

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.

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

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.
