Feature Setup...

In addition to routing your call through the D-STAR network, the gateway also provides the ability to simulcast on all three DV modules, make calls to specific callsigns, gateways, or multicast groups, linking to other gateways and “reflectors”, an echo test, and a voice ID for the WA6IRC D-STAR system.

To make life easy, program memories for each of your frequent contacts and gateway / reflector combinations. For all of the following features, program your radio with WA6IRC_G for RPT2 Call and set RPT1 Call to the local module you use to access the D-STAR system. The URCALL parameter is used to select the features listed.

LOCAL SIMULCAST

To transmit on all three local DV modules at the same time, program URCALL with the gateway callsign followed by spaces as necessary to fill all 8 positions in the callsign, WA6IRC_ _ for the IRC gateway.

URCALL: WA6IRC _ _

RPT1 Call: WA6IRC_C

RPT2 Call: WA6IRC_G

CALLSIGN CALL

To call a specific station, program URCALL with the callsign of who you want to reach. As with all of the gatgeway features, program RPT2 call with WA6IRC_G.

URCALL: KC1RON

RPT1 Call: WA6IRC_C

RPT2 Call: WA6IRC_G

GATEWAY CQ CALLS: D-STAR CALCULATOR

Here is a handy tool for figuring out gateway CQ call programming parameters: D-STAR Calculator. Select a port to access WA6IRC, your destination gateway and band to see a customized list of programming parameters. Click here for more D-STAR Calculator info.

URCALL: /W6HRO_B

RPT1 Call: WA6IRC_C

RPT2 Call: WA6IRC_G

MULTICAST GROUPS

A “Multicast Group” is a group of repeater/module link combinations defined by gateway administrators. For example, the ID-1 can use the /CA1200 multicast group which links several California 1.2 GHz DV modules. By programming URCALL to "/CA1200", DV traffic is sent to the 1.2 GHz modules of the repeaters defined in the “/CA1200” multicast group. This provides a way for ID-1 users to talk to other ID-1 folks around California. Current 1.2 GHz modules in the “/CA1200” group are:

K6CHO, Chico
K6MDD, Oakland
K6SOA, Laguna Beach
K6VO, Laguna Niguel
KI6JUL, San Jose
W6HHD, Merced
W6HRO, Anaheim
WA6IRC, Los Angeles

To use a multicast group, program URCALL with the group mnemonic, /CA1200 in this case. Remember, the /CA1200 multicast group requiers an ID-1 as all traffic in the group happens on 1.2 GHz.

URCALL: /CA1200

RPT1 Call: WA6IRC_A

RPT2 Call: WA6IRC_G

GATEWAY LINKING

Just as with analog repeaters, D-STAR repeaters can be “linked” to permit QSOs among all users of two linked gateways. “Reflectors” provide a way to dynamically link multiple gateways together for nets, etc. To see which modiles are available on a particular gateway, point your browser to the D-STAR Gateway page. Click on a gateway for a table of modules and recent activity.

For gateway and reflector linking, program your radio with memories for the links you wish to make, a "Gateway QSO" memory for the QSO, and an “Unlink” memory to drop the link when done.

To establish the link, select your “Link” memory, key up and give your callsign. The repeater will reply with a “Remote System Linked” message. Switch to your “Gateway QSO” memory and carry out your QSO. When you are ready to drop the link, key up on your “Unlink” memory. The repeater will reply with an unlink message. Remember that RPT1 Call will be the same for each of these memories; RPT2 Call will be WA6IRC_G.

To link to a gateway, program URCALL with the Gateway callsign / Module / Link. For example, W6HRO_BL for W6HRO, Module B. Carry out your QSO on your "Gateway QSO" memory, and unlink by keying up on your "Unlink" memory.

URCALL: W6HRO_BL
RPT1 Call: WA6IRC_C
RPT2 Call: WA6IRC_G

SWITCH TO:
URCALL: CQCQCQ
RPT1 Call: WA6IRC_C
RPT2 Call: WA6IRC_G
FOR QSO

TO DROP LINK:
URCALL: _ _ _ _ _ _ _ U
RPT1 Call: WA6IRC_C
RPT2 Call: WA6IRC_G

REFLECTOR LINKING

“Reflectors” are special gateways that “reflect” DV traffic back to all linked gateways for rebroadcast locally. This way all linked gateways hear all traffic from all of the gateways connected to the reflector, providing an easy way to hold a multi-gateway net, etc. on the fly. Currently there are 9 reflectors, REF001, 002, 003, 004, 005, 006, 007, 008 and 009. Each reflector has three modules, A, B and C. REF001, REF002, REF004 and REF009 are located in North America with REF001 offering high bandwidth. REF003 is in Australia and has limited bandwidth to North America. REF005 and REF006 are in the UK and both offer high bandwidth. REF006 is used for Germany. REF007 and REF008 are located in Italy. Reflector (and other D-STAR) activity can be seen at dstarusers.org

To link to a reflector, program URCALL with the Reflector callsign / Module / Link. For example, REF001CL for Reflector 1, Module C. Carry out your QSO on your "Gateway QSO" memory, and unlink by keying up on your "Unlink" memory.

URCALL: REF001AL
RPT1 Call: WA6IRC_C
RPT2 Call: WA6IRC_G

SWITCH TO:
URCALL: CQCQCQ
RPT1 Call: WA6IRC_C
RPT2 Call: WA6IRC_G
FOR QSO

TO DROP LINK:
URCALL: _ _ _ _ _ _ _ U
RPT1 Call: WA6IRC_C
RPT2 Call: WA6IRC_G

ECHO TEST

To check how you sound on the system, do an Echo Test. Set up a memory with URCALL set to WA6IRC_E. Key up and speak a few words. After you unkey, the gateway will play back your audio.

REPEATER ID / LINK STATUS

Key up and give your callsign. After you unkey, the gateway will play the system ID, or if they system is linked, you will hear a system linked ID. This, along with the Echo Test are quick ways to check how you are getting into the system and how you are hearing the repeaters.

Here is a table summarizing what we have just talked about. In each case you are transmitting on 2 meters, WA6IRC_C. Click here here for a couple other examples. For a good discussion and examples of manual programming for the ID-800, see AE7Q's ID-800 Usage page.
