That should read "the _old_ Mux B" of course.

We're curently getting some BBC channels from both the new high power
PSB1/BBCA on Ch43 _and_ from Mux B on Ch51.

Yes, you will, that's because the post DSO PSB1 contains the BBC channels that
are also in pre DSO Mux B.

I wouldn't mind so much but I'm now getting random picture breakup on _all_
PSB1 channels whereas I had perfect reception of all BBC channels before DSO
:o(

The duplicates in the 800s are still clear.

Could be, but the built-in signal meter is showing no increase in level over
what it was before.

Those meters typically read 100% at a level that is generous but far
from excessive, and continue to read 100% no matter how much stronger
the signal becomes.

Likewise, I came across a DTT box the other day which displyed the
signal strength immediately after every channel change. The signal
levels were 20dB more than they needed to be except for the ch29 mux
(this was Waltham and the aerial was Gp CD) which was inadequate. The
meter said '60' for ch29 and '65' for the others.

could it show higher? Shouldn't it be showing more? It might be that the
total sum of signals is overloading the tuner.

It was showing 91% with no increase on Ch43 compared to the other channels
since DSO started. It's _possible_ that 91% is as high as the meter will
read.

I then fitted a makeshift signal attenuator. Ch43 fell to 80% signal
strength with considerable improvement in picture quality but still with the
occasional glitch. The other channels now read as low as 25% signal strength
but with no noticeable loss of picture quality.

The 'quality' reading from the STB is 100% in all cases.

Our communal rigger is contractually obligated to supply a usable analogue
signal to all tenants on the estate up until the final switchover date so I
doubt he will make any adjustments to the system before then.

I still don't understand why it was necessary to lump all BBC channels onto
PSB1/BBC A when half of them are still available from Mux B on Ch51?

My Pioneer DBR-TF100GB appears to be doing the opposite, displaying only 91%
for a signal which is far in excess of that needed.

Because the BBC will only have one 'SD' mux after the second stage of
DSO.
