Redhill/Reigate

[John Nelstrop]

Does anyone have an up date on how good/bad the on digital reception is now
in Redhill?

Yeah, here's the update :- The BBC engineering dept tell me that the
Reigate transmitter is on 'Trade Test' until the end of August. What
that means in real terms is the follwoing availabilty :-

MUX1, on 31(BBC1,2,choice etc) : somewhere between 20&30% power
UNWATCHABLE
MUX2 on 21(ITV,ITV2) : NOTHING AT ALL
MUXA on 24 (CH5, SDN, etc) : strong(ish)40-60% carrier signal - NO
PICTURES though !
MUXB on 27 (Sky1, Cartoon net, Sky Sports1) : VERY variable signal 20-
50% Occasionaly watchable, although you can be watching a show for half
an hour fine, then major dropouts !!
MUXC on 39 (UK Gold, MovieMax, Sky Sports3) : Good Signal, about 60-70%
very occaisonal dropouts but on the whole a watchable picture
MUXD on 66 (Shop, Games, Horizon) : about 90% best of the bunch STRONG
signal, no problems at all . . .

So, every day when I get home I do an add channels, in the vain hope of
recieving something new !!

If anyone else knows anything new . . . then let us all know !

I can only comment on MUX A (SDN) & MUX 2 (ITV/CH4). There is no programme
feed for the MUX A yet, which is why you get just 'carrier'. I'm also fairly
sure this is the case for MUX 2 but should be installed soon.

However both transmitters are radiating on full power, there is no such
thing as 'reduced power' with DTT.

There are several outlets flogging On Digital boxes in Redhill.

Who's buying them then? Disappointed people?!!!

What is the difference between trade test & reduced power then ? at the
moment the signal I'm getting seems to vary wildly!, the power of the
signal can go anywhere between 20-60& on some MUX's . . . But MUX D
seems always to be at about 85%

Presumably the power output on these MUXs will stabilise when the
transmitter is commisioned ?

Trade Test means liable to interruption and not guaranteed. It may be that
broadcasting hours are reduced or that it can go down for an hour or an
afternoon.

No!
Power output is fixed, any fluctuations you detect are down to the quality
of your receiving equipment and atmospheric conditions.

Not wanting to be controversial or anything, but what is causing my
signal to fluctuate between 20% and 80% in the period of about 10 mins
under fine weather conditions ?

I was always assuming that some kind of engineering work was going
on . . . I understand also that all MUX's on this transmitter run at
0.1, not much I know . . . but I get an absolute crystal clear picture
on some MUX's ?

Now I'm terribly confused . . .

By the way you will need a wideband aerial for this transmitor as your
existing one will be what's know as type group C/D.

If you try and use your old one you will find that you have poor signal
strength and instability on some of the channels.
Additionally some of the MUX's (channels) will be completely missing.

The SDN mux (used for CH5 and BBC knowledge)
Is not as yet operational. However September the 19th should see this
resolved.

Hmmmmm, what frequency range is covered by a C/D aerial? Currently I am
recieving a 100% very good signal on MUX D (UHF66), and also I am
recieving a VERY strong carrier on MUX A (UHF24) . . . does this not
indicatre that I am already using a wideband aerial ? or is that wide
frequency range catered for by a C/D type anyway?

Also, fyi, I recieved a call from ON Digital customer support yesterday
(Bank Holiday no less!) concerning an email I sent to them. They have
informed me that the Reigate service will be flaky until 20/9. Thier
best advice was to hang on until then . . .
