Ok. I digged a bit deeper into to this. For some reason your local broadcaster sends 0xFFFFFFFF for the centre_frequency field of the terrestrial delivery system descriptor in the NIT (Network Information Table).
I've contacted the upstream author, but he doesn't think, it should be fixed in w_scan if the broadcaster doesn't send the correct transponder data as defined by the ETSI specifications. You wrote, that this has been working before. Can you name the version of w_scan which worked for you? Tobias
