I strongly believe that the information
"With this module you will also receive radio stations in digital quality, also known as DAB "
is wrong. DVB-T and DAB are totally different.
According to nl.wikipedia.org/wiki/Digitale_radio there is obviously a broadcasting of radio via DVB-T (other than in Germany), but I believe that will stop in near time as DAB is the new standard.
You can't receive DAB radio with a DVB-T module.
