Re: PCTV 290e - assorted problems

Hi Chris,

Take a look at this breakdown of muxes on the crystal palace
transmitter:

http://www.ukfree.tv/txdetail.php?a=TQ339712

You'll see mixed power levels and FFT sizes. I have the same thing
(albeit with a larger range of power levels) here in Mendip and as a
result its very difficult to get certain muxes.

You could try a variable attenuator to see if you can trim things a bit
to make the tuner/frontend happier getting a lock on all the muxes. It
depends on whether the problem is a weak signal or a too strong signal.

Of course it might be something else altogether, but this sort of thing
is precisely the kind of rubbish we have to deal with during the UK
digital switchover.
