    New version (cpy file to /tmp install green button>>yellow >>Manual Install BH packages)
    Thanks to @athoik
    Now everything works much better and faster.
    tested with OBH image

    my modification only for DAB / DAB +

    with buttons up / down
    choose the DAB band (frequency)
    Wait.(The first scanning of all MUX / transmitter radio stations takes longer.
    Later radio stations choice goes very fast.)
    With the blue button you can see the work and the list of found radio stations.

    Now you can choose found DAB radio stations with the Yellow button

    good work requires good signal / reception

    In my package for Open Black Hole image (not for Black Hole)
    you have all files for DAB/DAB+
    but not files for FM/USB modulation supported also by plugin (for them you need the other bin files I've put in earlier posts)

    The most important thing for good work is a good signal

    In my package for Open Black Hole image (not for Black Hole)
    you have all files for DAB/DAB+ (copy file to /tmp Open Black Hole image Install manual green button>>yellow>Manual install BH packages)
    but not files for FM/USB modulation supported also by plugin (for them you need the other bin files I've put in earlier posts)

    The most important thing for good work is a good signal
    I use an external dipole antenna made of two millimeters of wire (is not critical) and hanging above the window
    the formula is roughly
    150: f (DAB frequency) = length in meters
    example for 200 Mhz you need a dipole total length of 0.75 m or 75 cm.
    Of course, other antennas can also be used
    It is important that the signal is good.

    ==============================================================================

    Plugin you can use for now only with Open Black Hole image (not BH) due to file compatibility.
    For now only ARM processors
    (demand for a stronger processor for DAB / DAB +)

    This plugin uses RTL SDR USB dongle
    (its price ranges from + - 7 euros for cheap Chinese to 25 euros for better frequency-stabilized RTL SDRs)
    You can find among others on ebay , search for RTL SDR with RTL2832U+R820T2 chip.
    ======================================================================

    Installation
    first install bh package
    (copy to /tmp , install manual green button >> yellow >>Manual install BH packages for SDR_SDG_ARM_OBH_bh.tgz
    and for libfftwf_3.3.4-r0_armv7ahf-neon.ipk copy to /tmp , install manual green button >> yellow >>Manual install Ipk packages.
    The same for
    liquid-dsp_1.0+git6094+615a79a-r0_armv7ahf-neon.ipk

    Yesterday finally got my "USB 2.0 Digital DVB-T SDR + DAB + FM HDTV TV Tuner (RTL2832U + R820T2)"
    and I'm struggling to setup on VU+ ZERO with BlackHole 3.0.5 Got stuck and I need some help :)
    After connecting it od USB and rebooted VU+ ZERO, device recognized as Tuner B: Unknown frontend (DVB-T). Did not install other drivers because local DVB-T2 channels are found just like local FM stations...
    However, I like this Player and support for DAB/DAB+ as a major interest! First installed SDR_SDG_ARM_OBH_bh.tgz and from there my confusion, what's next? I installed all possible .ipk files from here but sound, audio I did not get, nothing, deaf. Also, have a problem with navigating the menus, I can only set the frequency and enter MENU to configure PCM: false / true and that's all, maybe drivers are a problem...

    Hey, can this RTL2832U + R820T2 chip scan DVB-T2 channels, or is it DVB-T only?

    Unfortunately DVB-T only.
    It works great on 4K boxes.

    For those who use Black Hole image and want to use DVB-T with the present Black Hole driver
    they need to copy r820t.conf file from my ZIP in to /lib/modprobe.d/

    Restart box/image

    I know.
    But that’s not for enigma SAT box software.
    A totally different story.

    Okay it was a tip, but where can I find the latest version? Dab + does not work here yet, although the station is 26 km away.
