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

SDGRadio DAB/DAB+ V3

New experimental version with my skin modifications for better support colors definitions e.t.c
sdgradio updated to support creating list of channels, by pressing menu a list of available channels names will be appeared.
In LOG (blue button) logs, you can see SNR e.t.c

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

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

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.

NEW version for Open Black Hole 4K for 4K receivers
Thanks to author @athoik / satdreamgr for nice work

After a long time I tested my RTL-SDR USB dongle again.
The cheapest ones cost only +-ten euros.
I use a better and more expensive version with a more precise frequency.
But FM and DAB + also work with the cheapest (You can find on Ebay)

I see that @athoik / satdreamgr is the image
Improved the plugin and now it really works really well
Especially DAB + works very well now.
This Plugin can only be installed on the Open Black Hole image due to the existence of appropriate versions of lib files.
The easiest way to install is directly from the satdreamgr image server.
For this purpose, we replace the opkg folder in /etc with opkg folder in my ZIP
Of course rename the original folder to for example opkg_org , or make a backup.
After installation, restore the old folder.
When you copied the opkg folder to /etc
go to
Plugins >> Download plugins>extensions>> and find sdgradio plugin
Install the plugin with OK (wait for the installation take longer)
When you installed the Plugin it is under the green button
Launch the Plugin
there with the red button you choose between DAB, FM, AM ...
With the left and right arrow keys you select the DAB frequency for example
(for other modulations and bands you change the frequency with the left and right arrows up and down)
With the green button you start Play
With the info (epg button) for DAB you get a list of channels on that DAB+ transponder / transmitter
With the Menu button you can configure some things
such as amplification and the like.
