Post by john zeissMany thanks. I do have a small pocket Sanyo fm/am radio which is very good.
I dont know if it's the specific area I live in, in north London,
Finchley/Mill Hill; but when I walk around with it, the reception quality
keeps changing almost at every corner I turn. So much so that I just don't
use it as a pocket radio anymore.
Which is why I thought buying a small pocket DAB might overcome that
changing direction reception problem?
That will probably depend upon whether you are near a DAB transmitter.
I used to use a DAB personal stereo, a Perstel DR101, and reception
quality often very poor compared to FM. However if you are in North
London, you might be near the Brookams Park TX, which might provide a
good signal, compared to FM, which doesn't have an additional TX in the
area.
Sound quality however is another matter. I stopped listening to DAB
because the poor sound quality was getting on my nerves. However these
days I often don't like the sound of FM either, due to most stations
using dynamic compression.
The problem with sound quality on DAB is the very old mp2 codec and the
bit rates being too low. The mp2 codec was designed to be used at about
256k, but 98% of DAB broadcasts use it at only 128k, which is only half
rate it was designed for. Modern encoders help slightly, but at 128k,
the sound quality is still very poor.
