Good day.

1. When switching between overlapping signals, "SF" works well, if there is no signal between them, no new signal is automatically found. I have to run "SF" manually. Does it repeat automatically at any "SF" interval when no signal is found?

2. Could the search information for another frequency appear instead of the song title so that this information can be shown to me "Launcher"?

Thank you and have a nice day

Hello, I own this dab usb receiver:

https://it.aliexpress.com/item/4001152198027.html?spm=a2g0s.9042311.0.0.27424c4dIdn5nv

I installed the antenna as required by rubbing the metal and gluing the copper antenna tab to it and placing the rest on the windshield.

Then I connected to the USB port of my android radio model:

https://it.aliexpress.com/item/1005001909554300.html?spm=a2g0s.9042311.0.0.27424c4dBUP9ZF

The DAB + Z app starts correctly and detects the DAB hardware, but after many tests I could never find any DAB radio stations :(. I'm desperate can you help me? What can I do? Thanks everyone
[Android Head-Units] IG_Vasilich:
@Matt89s

Where are you located? Is DAB or DAB+ transmitting in your country and available in your region?

Where have you scanned stations - in free air?

that windshield antenna is known to have bad reception, but not soo bad that no any station can be found...
[Android Head-Units] Matt89s:
I am in Italy near Rome, but for work I am in Rome. I understand that there is a DAB signal from the coverage reported by the websites. Incredible I'm going crazy! I have done all the tests in the world on how to position the antenna. Do not do more than do!
[Android Head-Units] SkyBeam2048:
Those windshield antennas are notoriously bad. I could not get any channel to tune in in my car parking lot and also lost reception immediataly when driving into any town. It only worked with some strong channels when being on the countryside on top of a hill.

Also note that some cars have tainted windows. Ford also does have windshield heaters which might impact reception too if you use an antenna glued to the inside.

All in all... please ditch the antenna and use a regular roof antenna to fix the problems. Your car might have a DAB-capable rooftop antenna already but you need to check if its got an amplifier and if the amplifier might be DAB-enabled or filtering the required frequencies. If in doubt replace the antenna with a decent combined AM/FM/DAB/GPS antenna. and get it installed properly. Preferably an amplified model.

You might also just get one of those magnetic roof antennas for a few bucks, at least to do a quick test if it's changing anything.

The antenna is the MOST IMPORTANT component for good reception. No amplifier or software can compensate for it.
[Android Head-Units] Matt89s:
Well then dab + will be postponed at the moment, I have no fantasy of changing antenna. Replacing and rewiring is a real pain, which at the moment I don't want to sustain. On the other hand, how do FM antenna dab splitters go? Always bad?
[Android Head-Units] TorstenH:
There are a lot of tuning companies which would install the antenna for you. Not as expensive as expected.

I have this antenna which is really good, looks better than a windshield antenna and includes the required wires:

[Android Head-Units] Matt89s:
Thanks for the advice, but if one day I need to replace it with shark fin similar to the original. How much could a professional replacement of antenna and cables to the radio cost?

Shark is also available from Bad Blankenburg

so it's just a question of taste. Due to the design, the FM reception of a shark antenna is worse.

I had to pay 120 Euro and no nerves.
[Android Head-Units] cuboidemobile:
Hi all, i have a 8227L with physical radio button (see pic attached). I would like to launch dab-z with that button rather than the system fm radio. Any idea how to do it? Thanks
[Android Head-Units] IG_Vasilich:
@cuboidemobile

This has nothing to do with DAB-Z, but with your HU. Try to get the answer in the topic for your HU, as there are very different solutions depending from HU manufacturer (e.g. for Joying there is FYTOneKey app from @HDWolf, that allows to remap some keys even without root, but i have no idea about 8227L).
[Android Head-Units] SaddleTramp1:
Hi all I am trying to create a DAB station logo for DAB-Z, can anybody give me info on naming it etc, I am informed the best size is 400 x 330. But is it possible to make it larger? I have a 12.3" screen and the logos are pretty small, also to actually name the file, do I name it as the station is named? for instance one I am trying to sort out is "Greatest Hits Radio South Yorkshire" what do I actually name the png file?

Thanking in anticipation
[Android Head-Units] IG_Vasilich:
@SaddleTramp1

i have best experience with logos max. 500 px on any side.

About naming- you can export your station list and post it here - i can help finding proper names.

Actually all names are in the file "dabservices.json" inside of your exported station list (in zip format). In this file for each block you should find "isProgrammeService"=true, and in that block you will see field "serviceLabel" that contains exact name of your station. You just need to name your logo file exactly as the station name, skipping any character not allowed in path (like ? or / or \ etc.).

If you have experience with logos in vector format (SVG) and are interested in scripting it - i have ready-to-use solution with scripts for checking missing logos and converting SVG files in PNGs with desired size (and some ready-made logos for my area - West Germany), but it is offtopic here.

[Android Head-Units] SaddleTramp1:
Thank You Very much indeed, I followed your instructions and I have now a fantastic logo file which suits my large screen at 500 x 500 pxl
[Android Head-Units] lacrimosa2k2:
hello,

i have tested the app with a ga9151b head unit, works nice, but randomly it kills the complete usb, internet usb stick and dab+ modul, after a second the internet conection comes back and the app ask access to the usb again, that repeat endless.

its not a loose cable or somethin, when i uninstall the app and use the orginal app all works fine without aborting.

any point who i can search the problem?
[Android Head-Units] IG_Vasilich:
@lacrimosa2k2

have you tried to use USB hub with external power? Do you have same experience when using only DAB+ stick (with USB modem pulled out)?

Yes it is the witson app it was perfect for a while but now drops out frequently. I stopped using your latest app app because of dropouts. The only other version of your app that works for me is the one before you introduced the nousb version that would close its self and reopen automatically and receive the signal.
[Android Head-Units] Helgeo:
Some people reported the high pitch sound when signal drops out. I have found that this only happens on stations that use DAB MPEG-2 encoding, stations using DAB+ (MPEG-4) just go quiet when the signal drops below a certain level. Here in Norway most stations are DAB+, but two of the more popular stations - P4 and Radio Norge still uses DAB (MPEG-2). Perhaps this can give a clue to troubleshooting the issue?

I have a suggestion regarding station logos, would it be possible for users to supply their own bitmaps and assign as station logos? Simply assign a bitmap to each station name. This way the favorite list could be presented as a grid with only station logo buttons making it possible to have more favorites in the same space. Also the station logo could fill the slide show area until an image is received.
[Android Head-Units] Cobra-2k:
Thanks a lot for your great work!

But i have a small issue, maybe something i have to set up!?

The function "Automatic start on USB device detection" is grey. i cant set it to on...

Any idea?
[Android Head-Units] sniktaw:
Uninstall and install the other apk in the package [emoji4]
[Android Head-Units] BlueVan:
That's an interesting point. Maybe there's a problem with the Android MPEG-2 codec. Here in the UK we still mostly just have DAB MPEG-2 broadcasts.

So Zoulou - could you tell us whether you tune in to any DAB (mpeg-2) stations?
[Android Head-Units] Kurt Lund:
I have a setup very similar to yours. Xtron HU (MTCD) with Malaysk v. 5.0 Firmware and DAB adapters from both Ownice and Joying (which seems to be similar, except for the plastic case). I also get the very annoying peeping sound when the signal is low. Somebody in the Forum suggested that it could have something to do with the difference between DAB and DAB+. Honestly I don't know if I am listening to DAB+ or just DAB, however from 1st October I will know for sure because on that day DAB is being turned off here in Denmark.

Regards

Kurt Lund
[Android Head-Units] Oberbergler:
I think this is normal on DAB when the signal is low. I had it on Wavesink`s DAB, Klyde`s DAB module and even on the xtrons DAB adapter, but I mostly had it with my old antenna which had a bad reception. On my new antenna I nearly never have signal drops and in my country in this two years since I am using DAB all stations have changed from DAB to DAB+. I am also experiencing high pitch sounds on DAB+, but only on a few signal drops and not so heavily.
[Android Head-Units] BlueVan:
Thanks. Similar to mine, but I have 320mm stick, yours looks like the 210 mm.

---------- Post added at 03:38 PM ---------- Previous post was at 03:25 PM ----------

Interesting... What country are you in?

From what I've read DAB+ is mostly broadcast at a lower bitrate than DAB (48 kbps vs 80-128 kbps) so may be inherently more resilient to poor signal. Also the codec for DAB+ (aacPlus HE v2) may be more modern than for DAB (mpeg-2) which is an antique.

OEM DAB radios I have used in the UK do not make the high-pitched noise as signal goes. They just go silent.

I live in a really bad spot for DAB/DAB+. I have to drive 20 minutes for a signal. As I travel around I'll see if I can get onto a DAB+ station. But the UK is only moving slowly to DAB+...
[Android Head-Units] Oberbergler:
I am from South Tyrol (Italy). My country is outonomous, so DAB+ is already available in 95 % of the country. In other parts of Italy (mostly the South) there is neihter DAB available. In South Tyrol you can listen to Italian, German, Austrian and Switzerland`s channels.
[Android Head-Units] realzoulou:
[MENTION=8018850]Helgeo[/MENTION]

Interesting theory about MP2 (DAB) and HE-AACv2 (DAB+).

But Germany since quite some time only uses the DAB+ standard. There are 0 services with DAB only. Nevertheless I had the high pitch audio issue just half a year ago, too. So I doubt that the DAB/DAB+ audio codec really makes any difference.

Regarding station logos: Please wait for my solution in the "Master Piece" release. All what you want will be available and even more! (except for the grid idea)
[Android Head-Units] realzoulou:
Then you installed the "nousbdf" version of the apk, where the option makes no sense and therefore is disabled.

nousbdf = No USB device filter
[Android Head-Units] realzoulou:
The app can do both, but I can only test DAB+ here in Germany.
[Android Head-Units] balders01:
Hi realzoulou

Fantastic Apk absolute light years ahead of the rest. I just have one question , the drop down is this right as its concealing the favorites button
[Android Head-Units] realzoulou:
This small "widget" is not part of the app. It's from your device.

But the app is the reason why you see this.

I added a feature that was requested by some users here: to send information about the current DAB station as broadcast intent. This is an Android mechanism to pass information from one app to another.

Unfortunately, this feature is now triggering this small window on some devices.

Something that I did not foresee, otherwise I would have added an option to disable this feature. I will add this into my next version.

For now I cannot give a hint on how to get rid of it.
[Android Head-Units] Cobra-2k:
my fault, working now, thx!:D
[Android Head-Units] rknuette:
You are probably using Car Launcher Pro. This is a feature of this software to show the current artist and song. You can switch it off in the settings of Car Launcher Pro (Music Player Settings)

[Android Head-Units] lacrimosa2k2:
a usb hub with external power is not possibil, the dab+ device is with a system connector direct plugged in the head unit, i htink its a usb line with another jack.

you mean, the app controlls the dab device to consum more power?
[Android Head-Units] surfer63:
What kills it? You are not really descriptive in what you tried.

Have you tried with only the DAB+ module or only the internet usb module? Does it still crash with either of them or both of them?

If it does crash with one of them, then that device is the culprit. If it crashes with both (but with only one connected at a time), there is something with the usb of your unit.

If it doesn't crash with either of the usb devices when "single connected", it is not the DAB+ module nor your internet usb-stick.

If it only crashes with both devices connected, it might indeed be a power problem, like @IG_Vasilich mentions.
[Android Head-Units] lacrimosa2k2:
@surfer63

my English is bad...

I try the translator.

when I start the dab-z app radio and internet work, after a short time the symbol for modem disappears and radio stops, then the symbol for modem comes back and the dab-z app requests access to the usb port.

this is then repeated a number of times.

that happens with and without a modem. when the radio reception is bad, it happens very often. after a restart it goes well for 15-30 minutes then it starts again.

edit:

ok so now i think i have found it, with dab-z or the orginal app the usb reset when service follow is enabled and dab signal get lost , i have not think about it the orginal app is crap and cant handle the service follow function god.
[Android Head-Units] tonimontoia:
@realzolou Hai friend a question about dab z, if you do an automatic search and Smith scans the logos automatically na not all the stations find them, but I already have the missing logos where can I insert them without losing those downloaded automatically? Thank you

[Android Head-Units] reptile-mtk:
Hi, I got a problem with the app.

I have a PX5 which is updated to Android 10 and a firmware from MIC. I use an old USB DAB box from Pumpkin.

My headunit is always in sleep mode but when it wakes up I'm always getting the pop up asking about starting DAB-Z if USB is connected (which I don't want because most of the time I listen to Poweramp). I thought I read something in the thread about that issue being fixed. But maybe I'm mixing things up. I had the problem on the stable version and I got it still on the beta.
[Android Head-Units] TorstenH:
You know there is a setting if DAB Z should start if a DAB box gets connected to USB?
[Android Head-Units] reptile-mtk:
Hi, I'm pretty sure that setting is not checked. But I'll double check.
[Android Head-Units] RobZen77:
Hi. Just reinstalled the app and mainly after 5-10 minutes of playing will crash. Sometimes it will play for like 30 minutes without issues. Also noticed the entire screen turns to this colour.
[Android Head-Units] reptile-mtk:
Hi,

i checked and the autostart is not activated. DAB-Z is still asking for autostart every time the radio comes out of sleeping mode. In addition every time I open DAB-Z, the app is asking for permission to access the USB port. Every single time. No matter what I do.
[Android Head-Units] Flosch_93:
@realzoulou

Hi, would it be possible if you add an option in the next version that you can select so that the app does not kill itself if there is no usb connection?

I have the app on a whitelist so that it won't be killed in standby. Unfortunately the headunit initializes the USB connection when waking up from standby and the app kills itself.

The background to this wish is that after waking up from standby I would have the headunit exactly in the same state as it was before standby.

I can still remember that this worked in an older version.

Regards Flosch_93
[Android Head-Units] TorstenH:
Have a similar problem. If the device comes back from sleep mode (and I set DAB-Z to be an app which should stay frozen in memory before) DAB-Z is still running without sound. Seems like the app needs to do a re-init or something like this. Because the app works after an restart of the app.
[Android Head-Units] pug304_:
same behavior on my box after migrate to hal9k mod v5. Sometimes it occured on mod v4.x.x too. in most cases it is OK to switch sender, sound will come back after
[Android Head-Units] Flosch_93:
Try doing this in this state with root rights:

echo "0"> /sys/bus/usb/devices/3-1.2/authorized

then

echo "1"> /sys/bus/usb/devices/3-1.2/authorized

where "3-1.2" must be replaced if necessary. This app will help you:

Usb Host Controller - Apps on Google Play

Take control over your connected USB devices with this application!

play.google.com

This should virtually initialize the dab receiver.
[Android Head-Units] TorstenH:
I think it would be better if DAB-Z would do this job as soon as no adapter or missing unit gets detected during normal operation.

Because this would help @Flosch_93 too.

On the other side there is no stable way to trigger something directly after sleep mode.
[Android Head-Units] Flosch_93:
Can you tell me which MCU version you are using? I am also on Hal9K V5 and I have the impression that the USB connection is disconnected before the standby. And the app kills itself when the headunit is switched off.

I don't understand why the app is still open for you after you wake up the head unit.

Hi @realzoulou

Could you check the issue with last char sometimes missing in station name? https://xdaforums.com/t/dab-app-real-zoulous-dab-z-app-official-support-thread.3609608/post-85144395

I will install v110 to check if seldom silence after app start is gone.
[Android Head-Units] realzoulou:
@IG_Vasilich I never saw this issue myself. I see wrong characters in DLS text often.

e.g. in Gigi D'Agostino always the ' character is wrongly displayed as ¿. When I analysed it, it looked to me that the encoding was already wrong. Stupid damn EBU character set of DAB !

If you send a raw recording of such a station (1 min is enough) then I can look into it.

Generally, I lost my passion for DAB-Z app. This is why I was "absent" since a few months.

Only the issue with the crash of the public 1.8.105 "motivated" me to continue now. I get a large number of 1-star ratings because of this (and direct emails), while still 5 star ratings also coming in.

I will make 1.9.110 public asap and then not sure if I can motivate myself to continue...
[Android Head-Units] TorstenH:
Why is your app for free? I know there is the donation function but I think it should be at least in the 5 EUR price range.

[Android Head-Units] realzoulou:
@TorstenH Thanks a lot.
[Android Head-Units] IG_Vasilich:
I am talking about station names, not about DLS. Do you need raw recording for that to be able to analyze names? Or can i somehow create dump from the scanning process?

About DAB-Z generally: have you lost your passion on it because of technical standards DAB based on (yes, i know - used standards can be really frustrating)? Or because your interests were shifted to smth else? or any other change in your personal life?

I also have donated today, to little support all your work on DAB-Z.
[Android Head-Units] realzoulou:
Yes, I understood that it is the station name.

When switching to a new frequency, first the whole ensemble information must be gathered. This takes about 2-3 sec and it is the same procedure as in scanning. So a scanning is just a) select frequency, b) gather ensemble, c) go-to next frequency.

So, a raw recording file of when you switch to the station which wrong name from a station on a different frequency/channel will allow me to see the whole ensemble info.
