OK, thanks, but I'm using an RTL-SDR dongle and I've already tried lowering the gain, but without success.
For now, I've given up on the idea of ​​receiving DAB...

just a note:

 

in my case DAB-Decoder is VERY sensitive to wrong Frequency Setting and strong Signal. 

so if any problems, try ATT and vary the Frequency a little bit.

 

-> using my cheap RTL Device is perfect for DAB here, with the RSPduo there is no chance, as even a small antenna is overloading the input (~15km direkt line of sight to two Transmitters

Thank you very much Albert !

The yellow dotted lines designate the bandwidth of the DAB demodulator.

The DAB signal has a bandwidth of approx. 2 MHz and is not in the FM band (87 - 108 MHz), but around 200Mhz.

Here in Vienna we have 3 active DAB+ channels with 40 programs in sum.

178.352 MHz (channel 5C)

180.064 MHz (channel 5D)

211.648 MHz (channel 10B)

Albert,

You answered my question about the new DAB function in Openwebrx version 1.3.

However, I think you misunderstood my question, unfortunately.

I'm familiar with DAB, but I was asking what should appear in the small window (a screenshot was attached...). I receive many stations here on the FM band.

Also, what are the yellow dotted lines at the top of the waterfall display for?

(Albert, I couldn't open your .tiff file.)

Hi Robert,

explanation here: https://en.wikipedia.org/wiki/Digital_Audio_Broadcasting

You have to tune to one of the channels in your region in order to decode the transmissions.

Albert

Hello everyone,

I just installed the October 11, 2023 version of OpenWebRX.(V1.3.0)
The new feature (for me) is that there's now a "DAB" button that opens a small "Loading" window in the bottom left corner (which is empty).

I don't understand how it works. Is there an explanation somewhere?

Thanks
