Overview[edit]

The DV4mini is a tiny USB communication device for several digital voice communication standards.

The following DV modes are currently supported:


Running a small control panel software available for Windows and Linux (requires Mono) running on a PC, Tabletcomputer or several thinclient boards (Raspberry Pi, Banana Pi and others), the DV4mini provides access to the amateur radio DMR-network via reflector connections.
To communicate via such a hotspot, a transceiver capable of the used DV mode is necessary to operate, the hotspot provides only an access gateway to the selected infrastructure.

Functionality[edit]

Original DV4mini software has limitations to access the so-called DMR Reflectors. That is the reason why we did mapping of talk groups into reflectors.

Timeslot or Talkgroup selection are currently not supported by the original firmware software. This is also the reason, why no private voice or data calls or direct repeater links can be made when using DV4mini with original software.

Starting BrandMeister version 20160105 we have a new function of Extended routing for DV4mini and this feature now is also included in the DV4MF2 Control Panel.

Configuration[edit]

DV4MF2 MultiFunction ControlPanel set for BrandMeister[edit]

The DV4MF2 Control Panel has been developed by DL2MF since November 2015 with the goal of seamless integration of all features of DV4mini and compatible operation to the original control panel software. After the formal review it now has officially been granted to be released by DG1HT since Jan, 3rd 2016.

The current software is available from the side menu of xreflector.net and was last updated on the 3rd March 2010, so it is as up-to-date as it gets. It is available as a Raspberry-Pi image or a Windows application. The latest and only available firmware is Ver.1.77.

Highlights of the DV4MF2 Control Panel (for archive purposes):


The compact view of the DV4MF2 Control Panel has been optimized for smaller 8" tablets and normal daily operation. Support of very small displays like the touch display with 480x320 pixel was not in focus, although it also can be used with this, vertical size fits already perfect.

Follow these tips for a successful BrandMeister connection with a DV4Mini.

DV4Mini Operational Settings.jpg

A - 7 Digit DMR Id B - with a 2 digit ESSID extension

C - Your location whether a town or county D - QTH Locator - must be 10 - digits like jn05vs23WR

Without a 10 digit locator the map displayed in BrandMeister defaults to somewhere in Austria.

E - DMR if you wish this mode F - your operating frequency - avoid the satellite band.

Next go to the Expert Settings, before returning to this screen to click on W to connect to the network.

The Expert Settings

G = Local Mode, unless you are experienced in networking. H = Normally 0 but determined by experimentation.

I = BM - BrandMeister J = Select the server closest to you.

K = passw0rd unless you have changed your personal password in Self-Care

Now return to the first screen and click on Connect. The connection should be confirmed in a green font to the right hand side connection box and in purple in the traffic box at the bottom.

Operating Procedures

Normally at this point the Dv4Mini is transparent, and all your operations will take place using a full code-plug on your terminal (radio).

For example in a basic terminal with 16 channels is a Zone, it can be a calling channel, plus a selected number of favourites and conversation channels.

On the UK BrandMeister Server, 2350 is the main centre of activity with 235 as a secondary, with 2351, 2352, 2353 as conversation channels.

For perfect control of the DV4Mini it is also recommended that an auxiliary button be programmed with group call 4000, to sever a connection between the server and one TalkGroup, before calling on another.

From time to time it may be necessary to close the software and restart it from the desktop, should the server connection terminate unexpectedly.

The Technical Stuff The prerequisites of this control panel are:

Version history:


In easy terms connect to 4000 on the screen and use TalkGroups direct from your code plug
