Tuned in last night and had no audio for some reason, 100% my issue 27.5w is not chaning anytime soon my local TX (which I can walk to) still has a dish pointing in the wrong direction. It is going to take a long time for A****A to make all the changes. Driving to NW spain in a few months will take a 80cm with me and shall see if we get any RX of 15w spot
 
We still use it every day and it has to be said it has lasted a heck of a lot longer than I thought it would when this all started. I never thought I would see the satellite swap and MEV etc.

However they can't just replace it and turn it off in a matter of weeks and the 27th rumour coming out of GC was just that. This also means that the test transmissions at 15W will presumably become permanent and at the very least all the dishes at the UK TX sites as @Markjose mentions will have to be repositioned, then 27.5W can cease.
 
From looking at MB21's TX Gallery, most of the UK DTT transmission sites that appear to have Satback at the ready should their main feeds fail seem to be the around 50 so "main" sites where the fibre feed to the site could fail. Satback provides the backup for the PSB1&3 multiplexes, while PSB2 appears to rely on a different method (RBL?) or try to ride it out for the best! There's only one relay site I've seen (Bruernish on the Isle of Barra in the Western Isles of Scotland) that appears to have Satback on standby presumably when across sea links fail, and there is/was a few relay sites of Bilsdale that had to resort to emergency Satback installations when its parent failed (appearing to use Triax 80cm or 110cm dishes as standard?), but it would appear that there's almost certainly less than 100 sites that have a "permanent" Satback installation (as opposed to the higher numbers for the DAB networks), so how long dual illumination between IS901 & Telstar 12V goes on will depend on available labour to move dishes, weather conditions etc. as well as sending someone out on a ferry to the Isle of Barra! Nothing unusual about this, in countries where satellite feeds are used as a primary means of feeding terrestrial transmitters, different satellites are regularly jumped on to for various reasons e.g. the UK national DAB feeds used to be on 4.8E.

Good point! how many TX is there in the whole UK and how long does it take to repoint each dish to 15west? They may have teams organizing this In each area

I suspect when it happens it'll happen without public warning. It is after all only meant to be used "internally" by Arqiva and there's no need for them to mention such procedures to the masses.

we should visit William Hill to bet on the date I think..LOL
 
I know this is a little off-topic but I don't know if it warrants a new thread and this active one seems the best place to put it.

Also forgive me if it is a stupid question!

If an installation exists which receives the Satback channels on IS901 27.5w, which if I recall correctly are on the spot 2 beam, is it possible to receive what is on the east hemi beam without adjusting the dish? The footprint for this beam looks pretty huge and I think the TPs are C band rather than Ku but is it possible?

Theoretically yes but the C-band hemi beam downlink power is much less than the Ku European beam. You need a dish bigger than 1.2m to get the hemi beams

Thanks for the reply and map link - from that I see what you mean.

It also explains something else; on the spot 2 beam why with an essentially identical dish we get a better signal in Portugal near the border with Spain, than at more or less the southern tip of Spain.
 
now for more than an hour here in spain anyone know the reason please??
the most we have ever lost it for is maybe 15 min's
anyone know anything?
thanks

Same here in Portugal x 2.

Sat change?
 
or they have switched it off in favour of the 15w signal?
Sun outages dont last the hour plus it has been off...(time from the first email i received about this happening! Luckily i am in an astra 2 area!)
 
Gone here in Sweden too. -1 and a north wind, not a day for re-pointing.
 
OK, not an outage (at least not the sun).

Must be aliens
 
In my area, the BBC is gone, Intelsat 901 is still there at 27.5W! :)
It also left Simmin TV(?).

No signal here in the Canaries ATM - anyone else? Was Ok a couple of hours or so ago.
 
I don't understand why those in spot two don't check the signal and transponders remaining active on Intelsat 901.
As you can see on the other topic (27.5W), the satellite is still operational but with less active transponders.
Here is what I found after a subliminal scan.
So the radio muxes are still working.
But as I said, a scan from the center of the spot would be more relevant than what we do from the outside.
