Digital Spy poster.

Does anybody know whether the power level of transmission has now been
raised as a consequence?

Yes !!! It's been stated in this group by myself and others ad-infinitum
over the last few years.

Read this link I posted in here 48 hours ago :-

By the way, Post 56 in the Digital Spy thread I posted is rather ominous !

John

Please note the 8k mode is always better than the
2k mode in relation to impulse robustness -
independently of power level.

Not so for the 64QAM vs 16QAM modulation where
about a 2.5 times stronger signal (+4dB) is needed
to get the reception quality.

The Selkirk signals pre/post DSO.

PSB1 3 - 10 kW 16-64QAM
PSB2 3 - 10 kW 64-64QAM
PSB1 3 - 10 kW 16-64QAM - DVB-T2 Dec 2009.

COM4 3 - 5 kW 16-64QAM
COM4 .5 - 5 kW 16-64QAM
COM4 3 - 5 kW 16-64QAM

Lars :)

PS! Search a little BEFORE you ask

Finally some progress.

Can/has somebody posted a complete lineup of the stations on PSB-1?

Five yes? TeleG probably? BBC Alba maybe not?

And has Five gone from COM-1?

Is that BBC1 bitrate just an instantaneous value?

Yes I did.

And I did not see a complete listing of stations there, but
rather a disjointed discussion about somebody who had not
woken up, needed coffee, and was hopping from room to room,
and who posted a link to a DVB application which showed a
cut off list of stations on the multiplex.

So you ignored the advice in my post to read Post 54 ? The text body of that
contains what you wanted to know.

You get that reading with Stat-Mux channels. It's just the maximum possible,
so in this context is meaningless. Remember that PSB1 mux is being centrally
coded in London, unlike Mux 1 that for Selkirk was coded at BBC Glasgow, so
BBC 1 is certainly not FBR.
