One advantage of FM that wasn't mentioned was the short delay. I can
have several radios, all tuned to the same station (usually R4), on at
the same time so that I can follow a programme as I move about the
house. That doesn't work with DAB or DTV.


What is equally galling is that there is a difference between DAB
receivers too - and DTV ones. I dunno if it's intrinsic in the system or
just different makers implementation - I've not had the opportunity to
try two identical ones. Then, of course, you've got the delay some TV
receivers introduce to the sound to bring it into sync with the
picture...


It is difficult to get to the bottom of such matters. I did try for a while
asking one well-known 'maker' of DAB tuners what the jargon for one of
their prompted 'features' in terms of sound quality actually meant in terms
of what was being done to the data. I never got a clear answer, and suspect
the actual process was developed by someone else who hadn't told them.
Experienced similar responses in some other cases.

Slainte,
