I'll tell you what the problem is here, your terminology is highly
ambiguous. For example you refer to "overlapping multiplexes", by
which I think you really mean the same multiplex with overlapping
transmitter coverage areas, whereas I would use the term "overlapping
multiplexes" to mean two different multiplexes whose coverage areas
overlap. You also previously referred to transmitting multiplexes in
"adjacent areas", which I also thought you meant different multiplexes
at first.

Since when has a "muliplex" meant the entire countrywide broadcast system
for a given operator? A DAB muliplex last time I looked was a radio
transmission that had multiple different data streams embedded in it.

So, to answer your question: yes, DAB can use SFNs, whereas FM cannot
use SFNs.

Ah , finally.

digital radio system that's 10x as efficient as DAB should lead to the
transmission costs per station being 10x cheaper. As Richard said, it
isn't rocket science to understand why the costs should be 10x
cheaper, but you don't seem to accept this for some reason.

Simply because (and , ok , this is just my opinion , I have nothing to base
it on) the operators will charge based on what they can get away with , not
what it actually costs then + a bit of profit. If say DAB+ started up
over here do you honestly think if Digital One switched for example Capital
over to DAB+ from DAB they'd cut the charges by 70% (or whatever the bandwidth
ratio of DAB to DAB+ is , I can't remember)? Of course not. They'd claim
the quality is the same so why should they charge less?
