I'm sure they do. Same as with any form of broadcasting.
But it's not just in London. I have route I use quite often using back roads to Bognor on the south coast. FM is unusable for quite a chunk of that - DAB just fine.
My radio will switch from DAB to FM if the signal is bad. Obvious when this happens, due to the digital delay on DAB. And it doesn't happen often.
I would say DAB seems far more sensitive to the aerial used, though. Dunno why.
Are you really saying you can hear the difference in sound quality between DAB and FM or internet on a kitchen radio?
Surely being a sound engineer you should be able to 'put a finger' on what sounds different?
Remember some time ago making up a test with the same bit of R2 from DAB, FM, Freeview and AM. And asked which was which. The only one most got right was AM. ;-)

Roberts RD 21, no longer young, but the *buzz* particularly in male announcer voice reproduction has been there since DAB came along. FM reception in deepest Herts. is not good enough to compare. No current Internet comparison.

No such difference ever heard here. But then I've never owned a DAB portable.
My DAB set suffers from interference from phone chargers and other assorted generators of RF HASH. You haven't got some sort of wall wart/laptop charger/wifi extender plugged in near?
Dave
So how come it works in cars?
Jonathan
No, but there's a phone charger next to the one that works!
Would soldering a length of wire onto the end of the aerial to extend it help?
The engine noise masks most of its short comings. The only thing that DAB does better than FM is the silent gaps inbetween programme material.
I get quite a lot of DAB dropout driving on major roads in the North East so whilst I accept it might work in London and the Home Counties it is pretty poxy in large areas of the north (but then so are the trains).
I don't find that DAB in the car objectionable apart from the gaps in signal coverage when driving along minor roads like the A1 and M62.
It might work OK in London and the SE but that is the only place where it does! FM degrades gracefully whereas DAB is all or nothing.
Is it true that Classic delays its FM to try to eliminate this effect?
If you say so.
strange. With DAB in my car I can get reception all the way up the M6
The iStream94 is an excellent radio but I think you will find the software is Linux based- I stumbled across some details of the software when researching models.
Unlike some of the cheaper Internet Radios, the user interface is very straight forward and, above all, stable.
I use mine in DAB, Internet Radio, and Media mode - very occasionally in FM.
Even through the Howgills?

Some sort of higher frequency "edgeiness" and sounding if it's being driven into a 5:1 compressor fairly hard.
Learn?
yeh. Know what you mean. My Pi based internet radio tuner has the same on classic FM. Oddly, on Radio 3 it has not.
My guess is they are simply using less/more bandwith.
MP3 streams are not lossless.
You have the only FM receiver that doesn't suffer from multi-path, then?
Could be you're simply deaf. And can't hear anything above 4.5 kHz.
