Page 4: Capabilities
Capabilities: The DV4mini is a very small but also very capable USB Stick that can turn any PC into a Hotspot for the digital modes D-STAR, DMR, C4FM and APCO P25. It consists of a powerful 32 bit micro controller, a complete 70 cm/2 m transceiver and a modulator/demodulator for GMSK and 4FSK and a USB interface. -
Page 5: Digital Modes
Digital Modes: The DV4mini can handle five digital modes: DStar: D-Star was developed in Japan 1999/2000 especially for ham radio and it became the leading system worldwide due to its clear and relative simple user interface. Voice is being transformed by the AMBE Vocoder into a compressed digital data stream of 3600 bits/s. -

When you use TS2, you always transmit and receive on TG9 (local) This is then routed by the DV4mini and the DMR Plus system into the selected rooms. So on TS2 you use CC1, TG9. Again, you need to program your radio accordingly, and again do not forget to put TG9 into you receive group list! There are multiple DMR networks available: The DMR Plus network is developed and operated by the DV4 team, the... -

Make sure to have entered your CCS7 ID. The DV4mini will not be found without it. If you do not have a CCS7 number go to h ttp://dmr-marc.net/ and click on Register ID. It can take up to 72 hours until you get your number by email. After starting and setting up the software one now has a Hotspot for the 70 cm/2 m band and it can be used with any digital radios in the supported modes. -
Page 9: Dcs (Digital Call Server)
This increases the chance to find a QSO partner - which is one of the reasons why reflectors are quite popular. The following systems are operational: DCS (Digital Call Server): DCS is the most modern D-STAR reflector system and used worldwide. Many countries use their own reflectors which differ from each other by their 3 digit number. -
Page 10: Dplus Reflectors
DPlus reflectors: They were the first generation D-STAR reflector system. Although it is getting old it is still used intensively in a number of countries (mostly english speaking ones like USA, UK and Canada but even in Germany there are a few operational). -
Page 11: Operating Modes
Operating modes: Digital ham radio repeaters are connected via reflectors. This allows for worldwide connections from one repeater to another. The DV4mini makes its own connection to this reflector network and gets access to all connected ham radio repeaters. The hotspot includes a low power 70 cm/2 m transceiver. All voice communications on the connected reflector will be transmitted by the hotspot on 70 cm/2 m and one can listen and transmit with a digital radio. -

Page 13: Antenna
Antenna: Comply with your country’s regulations regarding automatic operation! The DV4mini requires an antenna. It must not be used without an antenna. You can use the commonly available ‘rubber ducks’ with a SMA connector. The DV4mini must be used only when you are nearby. Unmanned operation requires separate licenses or permits in almost all countries. -

http://dj0abr.de/german/technik/dds/wsprbanana_install.htm An alternative approach was found by DL3MX which is described in detail in a separate document (http://dv4m.ham-dmr.ch) and works on nearly all Debian based computers and is simple and quick. We realize that this may overwhelm some hams, so we created complete images for the important computers which are also downloadable from http://dv4m.ham-dmr.ch ... - Page 16 Select the microphone and speaker you want to use (We suggest a USB headset) Then click on the MIC is Off button to turn the microphone ON: Now you can use your DV4mini without an external radio.

Page 18: Bootloader/Firmware Update
In the monitor window you may find diagnostic information which are created by various program segments. They are for experts but may be of interest for regular users as well. On the lower screen segment you find status reports. CPU usage is shown as a bar on the upper right. - Page 19 Now the firmware will be updated. When it is done end the program and restart. It may take a little while until the DV4mini is found again. Be patient. The boot loader is protected. Even with a power outage or interruption of the USB interface the update procedure can be repeated.
- Page 20 You need to connect the red marked points for example with tweezers while inserting the DV4mini into the USB interface. The boot loader will start with LEDs in color. Now you can start the user interface dv4mini. Go to expert settings load the new firmware by clicking on “Flash Firmware”.

Control Panel expert settings DV4mini list and auto connect: The list shows all DV4minis found in your local network and their status. If you run a DV4mini without the user interface then you have to start the program “dv_serial” on this computer. Usually “auto connect” should be checked. The software will automatically connect to the next available DV4mini. -
Page 22: Language
Language: English or German. This setting changes the language of the user interface and also the language of any messages. Select next location: This is where the closest DMR Master is selected. You can actually operate via any master worldwide but should select the closest for the shortest ping time. - Page 23 as green, yellow or red. After 10 seconds go up or down for 100 Hz and try it again for 10 seconds, so you get a good average You try to get it green or at least yellow. When you are done, go to another reflector and connect. Then pus the Echo button on the right of the reflector number.
- Page 24 Operating without a user interface: The DV4mini starts up with the last selected configuration and connects to the last used reflector when only the program dv_serial is started from a console. This allows for an extreme power savings operation, which should make Linux purists happy. However it also works in Windows the same way. Copyright: ...
