From: "Simon Kilvington" <s.kilvington@xxxxxxxxxxxxxxxx> > is there no way to tell without having to try each frequency? The idea of the frequency_list_descriptor is that the receiver tries _all_ frequencies and decides which one it gets the best signal from. Actually, I think it should work the other way around: When a receiver scans for multiplexes, and scans all frequencies, it might find the same contents from several transmitters. The frequency_list_descriptor allows the receiver to identify which multiplexes carry the same contents, so that it can then select the multiplex with the best signal.
