=== Developer C API ===<br />
<br />
This API works with Linux and MacOS. The Application needs to be linked against libmcsimple.[so/dylib] which connects via unix domain sockets to the driver service which runs as a server. The driver accesses the native USB userspace interface on each system and does not need any kernel driver.<br />
It can be found in /opt/lib<br />
<br />
The driver package uses LD_PRELOAD, /etc/ld.so.preload, for developers and integrators who directly access the driver this is not needed, be sure you install the driver with the -service flag ./sundtek_netinst.sh -service, full driver releases (no netinst versions) can be downloaded from https://sundtek.de/media<br />
The driver package also includes drivers for Sundtek TV devices.<br />
<br />
All devices come with a unique serial number, the serial numbers can be used for handling multiple devices and storing unique channel lists.<br />
<br />
Basically the API needs only a few commands:<br />
<br />
FM Radio:<br />
<br />
<pre><br />
fd = net_open("/dev/radio0", O_RDWR); // open device node<br />
net_ioctl(fd, command, parameter);<br />
net_close(fd);<br />
</pre><br />
<br />
For DAB/DAB+<br />
<pre><br />
fd = net_open("/dev/dab0", O_RDWR);<br />
net_ioctl(fd, command, parameter);<br />
net_close(fd);<br />
</pre><br />
<br />
In case you want to access the PCM samples directly you can use net_read(fd, buffer, buflen); on the corresponding device. The driver server has the option to play back the samples directly so no audio handling is needed by the application. It also has the advantage that audio can stay in the background even if the application is closed.<br />
<br />
The access to the dab / fm radio node is exclusive, if dab is used fm will be locked and vice versa. Care needs to be taken that some commands might introduce a delay eg. switching the radio mode and changing channels (eg. for DAB/DAB+). Switching from FM<->DAB needs around 4 seconds, changing FM radio station takes less than 100ms, changing DAB Services less than 1 second as long as they're available on the same Ensemble.<br />
<br />
Switching the radio mode between DAB and FM will also mute the audio stream, audio has to be unmuted manually by the application.<br />
<br />
Additional features are available, eg. detect connect/disconnect devices dynamically. Headers are available in /opt/include, libraries in /opt/lib<br />
<br />
Also to note, there might be some other libraries using net_xxx commands, in case you're running into a collision please contact sundtek via email.<br />

=== Developer C API ===<br />
<br />
This API works with Linux and MacOS. The Application needs to be linked against libmcsimple.[so/dylib] which connects via unix domain sockets to the driver service which runs as a server. The driver accesses the native USB userspace interface on each system and does not need any kernel driver.<br />
It can be found in /opt/lib<br />
<br />
The driver package uses LD_PRELOAD, /etc/ld.so.preload, for developers and integrators who directly access the driver this is not needed, be sure you install the driver with the -service flag ./sundtek_netinst.sh -service, full driver releases (no netinst versions) can be downloaded from https://sundtek.de/media<br />
The driver package also includes drivers for Sundtek TV devices.<br />
<br />
All devices come with a unique serial number, the serial numbers can be used for handling multiple devices and storing unique channel lists.<br />
<br />
Basically the API needs only a few commands:<br />
<br />
FM Radio:<br />
<br />
<pre><br />
fd = net_open("/dev/radio0", O_RDWR); // open device node<br />
net_ioctl(fd, command, parameter);<br />
net_close(fd);<br />
</pre><br />
<br />
For DAB/DAB+<br />
<pre><br />
fd = net_open("/dev/dab0", O_RDWR);<br />
net_ioctl(fd, command, parameter);<br />
net_close(fd);<br />
</pre><br />
<br />
In case you want to access the PCM samples directly you can use net_read(fd, buffer, buflen); on the corresponding device. The driver server has the option to play back the samples directly so no audio handling is needed by the application. It also has the advantage that audio can stay in the background even if the application is closed.<br />
<br />
The access to the dab / fm radio node is exclusive, if dab is used fm will be locked and vice versa. Care needs to be taken that some commands might introduce a delay eg. switching the radio mode and changing channels (eg. for DAB/DAB+). Switching from FM<->DAB needs around 4 seconds, changing FM radio station takes less than 100ms, changing DAB Services less than 1 second as long as they're available on the same Ensemble.<br />
<br />
Switching the radio mode between DAB and FM will also mute the audio stream, audio has to be unmuted manually by the application.<br />
<br />
Additional features are available, eg. detect connect/disconnect devices dynamically. Headers are available in /opt/include, libraries in /opt/lib<br />

<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />
<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />

<hr />
<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />
<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />

<br />
=== C API ===<br />
<br />
This API works with Linux and MacOS. The Application needs to be linked against libmcsimple.[so/dylib] which connects via unix domain sockets to the driver service which runs as a server. The driver accesses the native USB userspace interface on each system and does not need any kernel driver.<br />
It can be found in /opt/lib<br />
<br />
The driver package uses LD_PRELOAD, /etc/ld.so.preload, for developers and integrators who directly access the driver this is not needed, be sure you install the driver with the -service flag ./sundtek_netinst.sh -service, full driver releases (no netinst versions) can be downloaded from https://sundtek.de/media<br />
The driver package also includes drivers for Sundtek TV devices.<br />
<br />
All devices come with a unique serial number, the serial numbers can be used for handling multiple devices and storing unique channel lists.<br />
<br />
Basically the API needs only a few commands:<br />
<br />
<pre><br />
fd = net_open("/dev/radio0", O_RDWR); // open device node<br />
net_ioctl(fd, command, parameter);<br />
net_close(fd);<br />
</pre><br />
<br />
Additional features are available, eg. detect connect/disconnect devices dynamically. Headers are available in /opt/include, libraries in /opt/lib<br />

<br />
=== C API ===<br />
<br />
This API works with Linux and MacOS. The Application needs to be linked against libmcsimple.[so/dylib] which connects via unix domain sockets to the driver service which runs as a server. The driver accesses the native USB userspace interface on each system.<br />
It can be found in /opt/lib.<br />
<br />
The driver package uses LD_PRELOAD, /etc/ld.so.preload, for developers and integrators who directly access the driver this is not needed, be sure you install the driver with the -service flag ./sundtek_netinst.sh -service, full driver releases (no netinst versions) can be downloaded from https://sundtek.de/media<br />
The driver package also includes drivers for Sundtek TV devices.<br />
<br />
All devices come with a unique serial number, the serial numbers can be used for handling multiple devices and storing unique channel lists.<br />
<br />
Basically the API needs only a few commands:<br />
<br />
<pre><br />
fd = net_open("/dev/radio0", O_RDWR); // open device node<br />
net_ioctl(fd, command, parameter);<br />
net_close(fd);<br />
</pre><br />
<br />
Additional features are available, eg. detect connect/disconnect devices dynamically. Headers are available in /opt/include, libraries in /opt/lib<br />

=== C API ===<br />
<br />
This API works with Linux and MacOS. The Application needs to be linked against libmcsimple.[so/dylib] which connects via unix domain sockets to the driver service which runs as a server. <br />
It can be found in /opt/lib.<br />
<br />
The driver package uses LD_PRELOAD, /etc/ld.so.preload, for developers and integrators who directly access the driver this is not needed, be sure you install the driver with the -service flag ./sundtek_netinst.sh -service, full driver releases (no netinst versions) can be downloaded from https://sundtek.de/media<br />
The driver package also includes drivers for Sundtek TV devices.<br />
<br />
All devices come with a unique serial number, the serial numbers can be used for handling multiple devices and storing unique channel lists.<br />
<br />
Basically the API needs only a few commands:<br />
<br />
<pre><br />
fd = net_open("/dev/radio0", O_RDWR); // open device node<br />
net_ioctl(fd, command, parameter);<br />
net_close(fd);<br />
</pre><br />
<br />
Additional features are available, eg. detect connect/disconnect devices dynamically. Headers are available in /opt/include, libraries in /opt/lib<br />

<p>194.96.9.215: /* C API */</p>
<hr />
<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />
<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
Radio Application:<br />
<br />

./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />

<br />
=== C API ===<br />
<br />
This API works with Linux and MacOS. The Application needs to be linked against libmcsimple.[so/dylib] which connects via unix domain sockets to the driver service which runs as a server.<br />
Basically the API needs only a few commands:<br />
<br />
<pre><br />
fd = net_open("/dev/radio0", O_RDWR); // open device node<br />
net_ioctl(fd, command, parameter);<br />
net_close(fd);<br />
</pre><br />
<br />
Additional features are available, eg. detect connect/disconnect devices dynamically. Headers are available in /opt/include, libraries in /opt/lib<br />

<hr />
<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />
<br />
<pre><br />
sudo -s<br />

<hr />
<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />
<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />

<p>194.96.9.215: /* Set FM Radio Frequency */</p>
<hr />
<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />
<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />

<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />

<p>194.96.9.215: /* Tune DAB Service */</p>
<hr />
<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />
<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />

<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />

<p>194.96.9.215: /* Read RDS Data */</p>
<hr />
<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />
<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
Radio Application:<br />
<br />

<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player for X86-64 Bit Linux:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-x86_64-2019-07-28_07_05.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190728.0349.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />
<br />
<pre><br />

The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />

chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />

<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-fcc2a03-x86_64.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />

- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />

<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-fcc2a03-x86_64.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190727.1744.dmg<br />
- https://www.sundtek.de/media/sundtek_dab_fm_player_190728.0245.dmg<br />
<br />
First install the driver, afterwards run the DAB Player.<br />
The split driver also allows other application developer to integrate and use those devices.<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />

<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
In case you want to use our DAB/DAB+ Player:<br />
<br />
http://sundtek.de/media/Sundtek_DAB_FM_Radio-fcc2a03-x86_64.AppImage<br />
<br />
Be sure you set the downloaded binary to executable before trying to run it (right mouse click, permissions, check executable)<br />
<br />
=== Installation MacOSX ===<br />

<hr />
<div>== DAB/DAB+ ==<br />
<br />
The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation Linux ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />
</pre><br />
<br />
=== Installation MacOSX ===<br />
<br />
MacOSX:<br />
- https://www.sundtek.de/media/sundtek_driver_macosx_190727.1744.dmg<br />
- https://www.sundtek.de/media/dablet_v0.1.dmg<br />
<br />
First install the driver, afterwards dablet_v0.1.dmg<br />
<br />
=== Installation Raspberry PI ===<br />
<br />
In case you don't want to use our radio application, the installation is the same as on a regular linux system<br />
<br />

The DAB/DAB+ USB Stick decodes DAB/DAB+ onchip and transfers the decoded audio data fully digital to the host system.<br />
Currently Linux and MacOS are supported.<br />
<br />
=== Installation ===<br />
<br />
open a terminal and enter following commands:<br />
<pre><br />
sudo -s<br />
wget http://sundtek.de/media/sundtek_netinst.sh<br />
chmod 777 sundtek_netinst.sh<br />
./sundtek_netinst.sh<br />
</pre><br />
<br />
In case you want to distribute the local stations digitally you can also install our streaming server (again on the commandline)<br />
<pre><br />
just run following commands:<br />
sudo -s<br />
/opt/bin/mediaclient --installstreamer<br />

; to 810000 in absolute magnitude with gainmode FIX. With<br />
; gainmode VAR and FIX, they should never exceed 50000.<br />
;format=complexf<br />
;<br />
; The complexf_normalised format applies a compensation factor to the complexf<br />
; output to bring the range of the I and Q components to [-1.0 .. 1.0]. The<br />
; digital_gain is still applied on top of that normalisation.<br />
;format=complexf_normalised<br />
;<br />
; When the format is set to s8, the output writes I/Q 8-bit<br />
; signed integers, where the magnitude is multiplied by 128/50000<br />
; effectively mapping the gainmode VAR range of -50000 -- 50000<br />
; to -128 -- 128. For other gainmodes, use the digital_gain setting<br />
; to make sure you don't create clipping.<br />
;<br />
; The format u8 is the same as s8, except that the values are mapped<br />
; between 0 and 255. Use u8 for welle.io, qt-dab or other tools.<br />

[modulator]<br />
; Mode 'fix' uses a fixed factor and is really not recommended. It is more<br />
; useful on an academic perspective for people trying to understand the DAB<br />
; modulation.<br />
;<br />
; Mode 'max' is the normalization of every OFDM symbol. No overshoot, no<br />
; truncating, but varying output power (around 3dB) which might not be the best<br />
; for some power amplifier. The output samples are limited to a magnitude<br />
; of 32768.<br />
;<br />
; Mode 'var' uses the method specified in ETSI 300 798 Clause 5.3. This method<br />
; normalizes to 4 times the standard deviation for an approximation of the RMS<br />
; power. So around 6/100000 samples will be truncated and will introduce some<br />
; really minor distortion. But this mode also maximizes the output power. This<br />
; is the gain mode recommended for real world operation as it is based on a DAB<br />
; standard; the only difference is that ODR-DabMod internally calculates this with<br />
; 32-bit floats instead of 8 bits.<br />
gainmode=var<br />
;<br />
; In mode var, you can choose to normalise the samples to something else than<br />
; 4 times the standard deviation.<br />
;normalise_variance=4<br />
<br />
; Transmission mode<br />
; If not defined, use Transmission Mode 1<br />
;mode=1<br />
<br />
; The digital gain is a value that is multiplied to each sample. It is used<br />
; to tune the chain to make sure that no non-linearities appear up to the<br />
; USRP daughterboard programmable gain amplifier (PGA).<br />
; If there is clipping, the spectral quality of the signal will quickly deteriorate,<br />
; and wide-band noise will be generated.<br />
;<br />
; Be aware that there is a dependency with resampling.<br />
digital_gain=0.8<br />
<br />
; Output sample rate. Values other than 2048000 enable<br />
; resampling.<br />
; Warning! digital_gain settings are different if resampling<br />
; is enabled or not !<br />

<br />
; (DEPRECATED) CIC equaliser for USRP1 and USRP2<br />
; These USRPs have an upsampler in FPGA that does not have a flat frequency<br />
; response. The CIC equaliser compensates this. This setting is specific to<br />

[fileoutput]<br />
; Two output formats are supported: In the default mode,<br />
; the file output writes I/Q float values (i.e. complex<br />
; float) to the file. The I and Q samples can take values up<br />
; to 810000 in absolute magnitude with gainmode FIX. With<br />
; gainmode VAR and FIX, they should never exceed 50000.<br />
;format=complexf<br />
;<br />
; The complexf_normalised format applies a compensation factor to the complexf<br />
; output to bring the range of the I and Q components to [-1.0 .. 1.0]. The<br />
; digital_gain is still applied on top of that normalisation.<br />
;format=complexf_normalised<br />
;<br />
; When the format is set to s8, the output writes I/Q 8-bit<br />
; signed integers, where the magnitude is multiplied by 128/50000<br />
; effectively mapping the gainmode VAR range of -50000 -- 50000<br />
; to -128 -- 128. For other gainmodes, use the digital_gain setting<br />
; to make sure you don't create clipping.<br />
;<br />
; The format u8 is the same as s8, except that the values are mapped<br />
; between 0 and 255. Use u8 for welle.io, qt-dab or other tools.<br />
;<br />
