Welcome to the Web Pages of
The Ottawa Amateur Radio Digital Group (OARDG)

The Ottawa Valley D-STAR (sub-)network is made up of 2 major, Icom-hardware, D-STAR repeater systems with a primary mandate to connect with the USTrust database. These repeaters are VA3ODG and VA3AAR. In addition, in this area, there are several Freestar repeaters which function as hot spots, and there are also non-Freestar hot spots. All of these components are tied together into a homogenous sub-network through the use of a device called a Reflector. We currently use XRF018 B as the reflector or hub. XRF018 is technically a Freestar reflector but is compatible with all types of D-STAR. In fact, each device in the Ottawa Valley (sub-)network can be removed from the hub, very easily and connected somewhere else. All of these components are compatible with all common forms of D-STAR.


The audio from the hub reflector is streamed courtesy of the Almonte ARC and in memorium of Jack Thomas (VE3UPH)(SK)

Other Repeaters and Hot Spots


There are numerous hot spots in our area. These ensure continuous D-STAR connectivity throughout the Ottawa Valley. Hot spots are simplex frequency devices (usually) which extend all transmission/reception from a reflector or repeater though use of the internet.

Part of the table below is an excerpt from http://www.va3uv.com/freestar.htm

Please note that FreeStar Half Duplex (Simplex) Access Points require the user's radio to be in duplex mode (+/- DUP enabled with a 0MHz offset), set RPT1=Callsign as shown, and RPT2 = Access Point Callsign with a 'G' in the 8th position - e.g. for VE3FSR, URcall = VE3FSR RPT1 = VE3FSR B RPT2 = VE3FSR G. Very similar to settings for a repeater.

Non-Freestar Half Duplex (Simplex) Access Points permit the user's radio to be in simplex mode, and the setting for RPT1 and RPT2 are not critical. You may follow the same format as for Freestar hot spots.
