You should associate icons to the radio RDS name and not to the frequency as many radios have different frequency as you cange rĆ©gion while driving. I'm using navradio+ (5ā¬ app) as a substitute to the original radio app, you can download all countries zip files from there.
Guide for Adapting Radio Icons for Submissions
SeVeMaS There is this thing available. But you cannot have them saved as in the navradio+ app. At least in Denmark it works. You have to choose "others" when you select the region/city in your country selection. Then the logos will be assigned after the PI code (RDS data) broadcasted by the radio station.

I agree with you. This is how it should work.
The last few months I did hardly drive my car so I really can't test RDS right now.
But I have the idea that RDS still doesn't work correctly and that they implemented some semi-RDS like navRadio can also use. In NavRadio you can assign multiple frequencies for one radiostation. If RDS doesn't work correctly, it checks one of the alternate frequencies that you assigned.
I think the Dudu local radio does the same. You now assign a location/region where you are. If you select some frequency like 92.6 of station XYZ, it will of course be a "strong" reception in that region and it will have an icon belonging to a radio station. And then you possibly assign a few more stations for your region.
Then you start to drive outside your region, the signal gets weaker, the app starts searching for other frequencies with the same radio name in its frequency/name repository and finds the same station name/logo in its repository on 94.8 which has a strong reception in the new region, and switches over to the new frequency.
No RDS, just predefined alternative frequencies, and as a bonus you have immediately your logo as well.
This kind of "semi-RDS" or even "fake-RDS" could work really well, as long as you stay in your own country and someone made a proper selection of the radiostations over the country.
If I now have good "my favourite radio station" reception all over the country, I am happy with such a solution.
But maybe I am wrong in my assumption.

The RDS-PS, RDS-PI, RDS-PTY, RDS-RT(+) and RDS-TA/TP showing you informative text (RT) and switching to stations that currently broadcast traffic information (TA and TP) has functioned since approximately 2016/2017 on the units that have the RDS functionality enabled inside the FM chip. Earlier units came with FM chips without RDS support. Some of the very cheap 7731 units using a very cheap FM chip, still don't have RDS enabled in the FM-chip. Meaning that RDS will never (software based) function on those units as long as the FM-chip doesn't support it.
I am talking about RDS-AF. That has been non-functioning since 2015 as in China they do not use RDS-AF. Dudu is now trying to get that working for about a year.
About 6 months ago @DUDU-HUANG suggested to use the same pre-defined alternative stations for the dudu-radio, as can also be used within navradio. Having now the FM-<frequency>-<station>.png for (almost) all regions in a country makes me wonder if they use that system, maybe in combination with "real" RDS-AF. Note that for "smooth" functioning of RDS-AF, like builtin car radios use, you need to have 2 FM-chips. These units do not have that.
I cant upload files bigger than 3.7mb
But The stations here in austria have many equal pictures with different frequencies.
So i uploaded it to mega.nz

Xaver I noticed that the region you labeled is "Carinthia" (KƤrnten) state, rather than a specific city? Apologies for my lack of familiarity with local conditionsādo radio station frequencies in different cities within this state not have overlapping allocations?
LuckyZone
Hello,
Yes, i in Carinthia, the same radio frequencies are used in different cities as long as the coverage areas donāt overlap and thereās no interference. But i am Not to fimilar how this exactly is structured.
Should i better upload specific city?
I see That Klagenfurt is already there (its in Carinthia)
Xaver Due to the power and propagation characteristics of FM broadcasting, it generally ensures that radio station frequencies do not overlap within a given city.You can refer to the structure within "https://drive.google.com/file/d/1wTB84VRQpdIayRJXlNFZnq-GcD9VIE2w", creating a folder for each city.
