PROGRAMMING YOUR RADIO
There are a few things that you will need to know in order to fully
utilize the D-Star system. Use of the D-Star system not only includes
the WMPORN D-Star repeater, but eventually will include operation of
the D-Star Gateway connecting to other systems around the world. When you
are ready to program your radio you should take a look at the
DStar Programing Calculator Page written by Ed Woodrick to help in programming your radio.
Now that the gateway is operational you MUST be registered on one of the gateways
associated with the trust server. Most all of the US DStar repeaters with
gateways are connected to the same trust server. If you are registered on
any one of these servers you are able to use any of the gateways. To make
things simple, it is suggested that you be registered on your local system.
Since you can only be registered on one system being registered on your
local system is what the gateway operators have accepted as the standard.
For registration on the WMPORN gateway you will need to send email to
n8wkm at wmporn dot net. Sorry, spam is high, and if you are unable to
figure out that email address I would be concerned about your ability to
program your radio.
When programming your radio there are a couple of things to notice.
Each radio has a place to store special memories for digital repeaters.
These memories have places for additional information not needed with
analog repeaters. The additional information is used for what D-Star
refers to as routing. Because this is a digital system, data starts
streaming as soon as you press the PTT. This data can in fact tell the
repeater what it is that you want to do. It can tell the repeater who
you are (your callsign that you have programmed into the MyCall slot
in your radio memories) as well as what transmitters you want to begin
transmitting your signal.
Icom refers to these places in the memories as RPT1 and RPT2. This is a
fairly simple concept, RPT1 will always be the callsign of the repeater
that you are trying to access. RPT2 will be the repeater where you want
your signal to be retransmitted. Just for the record, any repeater that
you access will repeat your signal over the same band module that you are
accessing. If you access the VHF receiver, the VHF transmitter will retransmit
The trick to using the repeater is in putting the right information in the
right place. First of all, it is important to understand that ALL D-Star routing
information is the callsign of the repeater followed by a letter code that is
known as the route identifier. Please take special note that ALL route identifiers
go in the 8th position regardless of the callsign. For the WMPORN repeater
you would use "WX8GRR C", "WX8GRR B" or "WX8GRR G" at this time.
To make things perfectly clear "WX8GRR C" is associated with the 2m band module,
and the "WX8GRR B" is associated with the 70cm module. Though it is not in use
just yet, the 1200MHz module caries the designator of "WX8GRR A". Anything that is
headed out to a user on the internet such as another D-Star repeater or a DV-Dongle
user will include "WX8GRR G" which stands for "Gateway". The G module is actually
assigned to the computer that is attached to the repeater.
In programming your radio to use only the 2m Module, you can program "WX8GRR C" into
both the RPT1 and RPT2, or just into the RPT1 call. This will tell the repeater to only
retransmit your signal on the 2m transmitter. By changing the RPT2 call to "WX8GRR B"
you will effectively tell the repeater that you want your transmission to also go out
on the UHF transmitter. For more detail, please see
D-Star Routing Explained.

For more information about how routing works for the WMPORN D-STAR Repeater
project please send email to "dstar at wmporn.net" .
It isn't that hard to figure that out, and doing it that way helps to
keep that email address from being sent a bunch of garbage email.
