Will switchover improve the lower bandwidth channels?

Receive all Freeview channels fine... (except for times when atmosphere is
weird) - several channels I receive show as pretty high signal strength but
their picture quality is somewhat poorer than, for e.g. the BBC channels -
suggesting that the issue is one of lack of data not a weak signal. Is this
deliberate on part of broadcasters or will the improved signal integrity we
are promised with switchover mean they will ramp-up the bandwidth to take
advantage of it?... or is this the penalty of squeezing too many channels
into an already crowded frequency band and no amount of power uppage at the
transmitter will make any damn difference??

Many channels use a lower bitrate than the BBC does, this is probably what
you are seeing.
Increasing the power won't affect this but at switchover the capacity of
some of the multiplexes it increasing a little so one may see some channels
at a higher quality or more likely (judging by what's happened up to now) a
few extra channels.

Increasing power will not of itself increase quality if you are
already receiving an adequate signal.
But in addition you may take it as an article of faith that any
increase of available bandwidth for either televison or radio will
always be used to cram in extra channels rather than to increase
quality.

What, that some people will stick with what they've got because it's
better quality?
It'll be a bit late when all the analogue broadcasts are switched off!

Freeview can hardly fail. It's free, and they're turning off the only
free alternative.
(Does Freesat count? Don't know. I don't know a single non-techy who
has heard of it!)

Increased power wont upgrade the bit rate. You'll still get a blocky
picture but much clearer :/
