Probably I’ll develop as a plug-in as I have the radio interface available. Once working I could then make it a standalone program but that’s quite a lot of work.
One reason for DAB+ is I then have the classes available for future work, also I can listen to Jazz FM (UK) and also play DAB+ when we get good Tropo.
Currently using a nice 100 to 600MHz log periodic, am only ~8 km from the transmitter.
QT-DAB does work, drives the Airspy correctly. My birthday present from me to me in October will be my own DAB+ receiver app 😊 .
look for qt dab ... soft from jan
lots of hardware included (rtl dongle, sdrplay, lime, pluto etc etc) ... he even works on receive via dab and retransmit on analog fm stereo (if you use a pluto) ... then you can receive your favourite dab station on any normal fm radio in your house (retransmitting not finished yet)
jan is now on holiday but will be back in a few weeks (mid of july?!?)

Welle.io is not bad but uses a lot of CPU and I don’t think it drives my Airspy R2 correctly.
It depends. If it is built to use FFTW, then yes. The CPU-load in my case is around 17%.
But if I build Welle-IO using Kiss-FFT and compiled using fast-calls (option
-Gr), then the CPU drops to only 10%.
Edit: the Airspy problem is proably related to how Welle-IO handles SoapySDR. Not very good IMHO.
