will tranmission power improve after switch off?
 

I am receiving my transmissions from the Bluebell transmitter in Kent.
Power for Mux 2 and Mux A is low. I receive channels from Mux A but not Mux
2. This is not a problems as I have sky (for now) and I only use freeview
to watch different channels in different rooms and anyway analogue is still
there so I can get ITV and Channel 4 etc that way. I was wondering whether
there is the intention to increase to power of transmissions after switch
over? If they know they are transmitting on low power should they not be
trying to improve it?

Yes the power will increase after switchover.

The power cannot be increased before then because it would interfere
with the existing analogue transmissions.

It will also save a fortune in electricity as the megawatt transmitters use
a vast
amount. The latest lower power digital transmitters through high gain
aerials
and the overall reduced bandwidth will be a huge benefit. So will we see a
reduction in the licence fee! Running costs will be a quarter of what they
are
now at main transmitter sites.
Power output will go up, but that will only show that firms installing
"digital"
aerials, which don't exist, and power amplifiers have caused more harm than
good. Many will now have high gain aerials and preamps that provide a
signal that is far too strong. maybe it was a way of guaranteeing repeat
business to remove them at a later date or fit a new "type" of aerial !
Plenty of aerial fitting cowboy firms about.

Are you being serious? Or ignorant? Or are you just another stupid wind-
up merchant?

There are NO megawatt transmitters anywhere!

You are confusing transmitter power with ERP - the Effective Radiated
Power from the transmission aerial which is dependant on a number of
parameters - not least the height of the mast/tower on which it is
mounted!

In fact, as the power of digital retransmissions is constant (whereas
analogue signals vary over a wide range, depending on what is actually
being broadcast) considerable money is being spent at many transmitter
sites to install larger feeders to cope with this higher average power.

No doubt, now that you have been corrected, you will be only too happy
to pay a quadrupled licence fee to fund these essential upgrades ...

This may be an aerial issue rather than a power issue. The original
analogue aerial for Bluebell Hill was Group E, covering channels 35-68
(of 21-68) whereas the muxes causing problems are on A on channel 27 and
(worst) 2 on channel 24 which are out of range for the original aerial
group.

The current recommended aerial covering Bluebell Hill is W (Wideband) so
it looks like an aerial change is called for.

For info, the poster 'Clive' is best ignored, (s)he is a sad, lonely and
likely impotent individual seeking attention through attempting to bate
others and if ignored it will eventually shrivel and die.

erp does not depend on the height of the mast, except that then higher the
mast the greater feeder losses. the planned erp will depend on the
coverage required and will depend on many factors, terrain being one.

I suppose they might have all closed down, but you have checked this haven't
you?

Charles, with respect, I did say 'ERP ... is dependant on a number of
parameters'!

I was trying to simplify my response to an obvious idiot in the certain
knowledge that there are many others on this forum - yourself included -
with vastly superior knowledge of the subject than myself.

In the circumstances, I don't think my response was unreasonable ...?
