Configuration and Usage Details for SDV on
The SDV-Qt application was written to communicate to the user via traditional graphical windows. This version of SDV is distributed both in executable form with a Windows installer, and in source form, so it can be compiled to any platform supported by Qt, including Intel-architecture Linux. This page assumes you are using SDV-Qt on Windows.
SDV-Qt is the control interface, managing the Star*DV AMBE device and sending linking and other networking commands to the G4KLX ircDDBGateway program. So both programs must be running to have QSOs with Hams on reflectors or repeaters.
SDV can also manage a GMSK Modem, but the focus of this page is controlling the Star*DV AMBE 3000 device.
Launching the programs
Be sure the Star*DV is plugged into a USB port.
Start ircDDBGateway. You may want to set up a shortcut on your desktop with the GUI parameter. The target would be similar to "C:\Program Files\ircDDBGateway\ircDDBGateway.exe" -gui . Normally you won't look at this window, but it does show the real linking status, and the bottom of the windows scrolls the latest log entries. If there is a problem and an error message has scrolled off the screen, you can view the log file itself. It is normally found at c:/Users/youruserid/. Naming is ircDDBGateway-yyyy-mm-dd.log.
SDV-Qt Windows for Configuration and Operation
Main tab - this is the prime window for both configuring and operating.
Local Settings are similar to what you set up in a D-Star radio:
MyCall, normally your callsign
A 4-character string often used to indicate your radio, name if it fits or your CCS DTMF id. It is optional.
UrCall, normally CQCQCQ. While most linking is done using the Reflector and Mod drop-downs, you can also manually enter a traditional linking command, normally using the DPlus format, which is target reflector or repeater in positions 1-6, band module letter in 7 and L in 9. If you plan to do this often, it goes faster if you click the Presents menu item and save the URCall setting in one of the 10 slots. Examples of using URCall:
REF030CL will ask ircDDBGateway to link to Reflector 30C the next time you hit PTT
WW6BAYBL will issue a link for repeater WW6BAY module B
K1ABC CL (one space so C is in position 7) will issue a link to repeater K1ABC module C
RPT1Call, normally your call with the band module letter (in position 8) used when configuring ircDDBGateway's Repeater1 tab
RPT2Call, normally your call with G in position 8
Message is optional and can be any message that you want sent out each time you hit PTT
Use Modem should be checked if you plan to use a GMSK Modem running DUTCH*Star firmware. This means you will have an integrated D-Star Compatible RF Hotspot in addition to your AMBE 3000 PC-based access to D-Star reflectors and repeaters. This page assumes this box is unchecked, but if you do check it, be sure the modem is plugged in before starting SDV. Note that if you check it, you can then dynamically configure the modem's RX Invert and TX Invert settings.
Reflector is a drop-down list populated by the Hosts files (see Configuration tab). it combines the contents of DPlus/REF hosts, DExtra/XRF hosts and DCS hosts files. When you want to link to one of them, select it from this list. Example: REF012
Mod is the band module of the reflector or repeater you want to link to. Example: C
Link button - clicking this sends the Reflector/Mod information to ircDDBGateway requesting a link
Unlink button - requests an unlink
Info - requests ircDDBGateway to send back the linking status
Echo - Sets up a temporary Echo for whatever you transmit on your next PTT. Your transmission is sent to ircDDBGateway, not over the network, and echoed back immediately. Note that a better Echo test is to link to the E module of any REF reflector, for example, REF001E or REF030E. This will send your transmission over the network, DPlus will record it, then play it back over the network, giving you a better test of your entire system.
Use PC Audio/Use Spk/Mic lets you select whether you want to use the PC's speakers and microphone, or if you have a speaker/mike plugged into the Star*DV. The Star*DV is unusual, compared to other AMBE 3000 devices, in that it has a built-in codec and plugs for a speaker/mike, as an alternative to using the PC's soundcard. If you select Use PC Audio, you can then select which PC audio Out (speaker) device to use, and which In (microphone) device to use. If you plug in a device after SDV has started, pressing Refresh List will re-populate the list of available devices.
On rare occasions, you' may change a configuration value incorrectly, save it, then have trouble changing it back. In those cases, you may want to check where the values are actually stored.
On Windows, the QT functions save configuration values in the Windows registry. For Windows experts, you can see (and modify, if you know what you're doing) the config info. Just go to Windows logo at bottom left and select Run, enter regedit and hit Enter.
Navigate to HKEY_CURRENT_USER/Software/MC/stardv
If you want to see/change the usemodem parameter, go to HKEY_CURRENT_USER/Software/MC/stardv/starboard
Speaker/Mike audio level (volume) controls
