grdab info doesn't decode anything - instead, it continually spews the above error message. The command that I run is 'grdab info -f 227.36', as channel 12C is what's in use all over our country (NL).

Setup: gnuradio 3.8.2, uhd 4.0, gr-osmosdr 0.2.3, Ettus B210

grdab adjust mostly works. The DAB signal is clearly received, but the noise level outside of the signal keeps going up and down, and with it, the constellation goes from bad to good, and vv. This happens with a rate of about one cycle per second. Changing the PPM value has little effect as long as it's roughly around 0.

Welle.io picks up the DAB+ stations without any issues, showing a 13dB SNR, and no RS or AAC errors. PPM offset is reported as 1.15 ppm (-262 Hz)

Hey have you found any fix? Because I have the same error when using the dab_receiver example provided with gnuradio
Regards
