Digital Repeater Special Interest Group

The Oro Valley Amateur Radio Club "Digital Repeater Special Interest Group" was formed to support and engineer the addition of Digital Smart Technology for Amateur Radio to the existing OVARC communications infrastructure.  The goal of this group of dedicated Amateur Radio operators is to make the D-STAR and other digital voice communications technology available to OVARC club members as well as the Amateur Radio community.  The group has  installed a D-STAR UHF Repeater and Controller.  See below for details. Future plans include experimenting with new and existing Digital Voice technologies and to learn how D-STAR and other digital voice technologies can contribute to OVARC's public service activities.  To join the SIG and provide financial or technical support, contact Bob, KA7VPR, or send an email to This email address is being protected from spambots.

OVARC Digital Repeater System

OVARC operates the following digital repeaters

In addition, we have the linked analog system transcoded to D-Star reflector XRF310 Module E for normal operation. This allows D-Star users to link to XRF310E and talk/listen to the linked analog system. We plan on shifting reflectors from XRF310E to XRF310D for the Sunday night net. This will allow D-Star users from locations around the world to participate in our Club net. Club members with D-Star hotspots can use their D-Star radio to check into the net using the transcoder. D-Star will be unlinked at Main for the duration of the net allowing analog use of the repeater. The transcoder will be moved back to XRF310E at the end of the net. EchoLink operation continues also.

Registering Your Call Sign for D-Star

OVARC does not provide a D-Star registration server.  See below for registration instructions. 

Before you can use the REFnnnx reflector features of any D-Star repeater you need to register your callsign with the US Trust servers.  If your callsign is currently registered with any D-Star system then you do not need to reregister your callsign to use the W7AI system.  To see if your call sign is currently registered go here -   If your callsign is not registered, go to for instructions on how to register your call sign.  For a step-by-step example of the registration process go to .  

The only registration server in the Tucson area is at:

DO NOT register your call sign with more than one registration server.  Multiple registrations will result in problems connecting to reflectors and are difficult to fix.  If you think you have registered on any other system, check before registering your callsign a second time.

If you need to register additional terminals such as a hotspot always log in to the registration server that you used to register initally.  



Repeater Listings For Your D-Star Radio

If you get a new radio or need to update the repeater listings in your existing radio, go to  You can download repeater listings suitable for various D-Star radios in repeater list or memory list format.  The downloaded files can be imported into the ICOM programming software or RT Systems software.  This site also has repeater maps so you can see where repeaters of interest are located.  These lists are kept up to date and include our W7AI repeater.
