Hi I am a new member to this site. I would like some advice. I am in algarve in my touring caravan and car I have a 40cm multmo satalite dish and using a Ross HD receiver. I can get astra 19degs. I heard Intel sat 907 27.5 w broadcasts BBC. Itv chanel 4+5 etc. I tried to pickup the Intel sat but couldn't. I did get onto hispasat at 30 deg w. My question is what size dish and reliever would I have to purchase to receive the Intel sat 907. Also we will be moving to southern Spain in the new year would it be possible to receive it there many thanks Martin

A little less analogue, and a lot more crap.

English channels on the western satellites are BISS encrypted for the transmission, I doubt the Ross receiver has the ability to work with these channels.

Intelsat 907 at 27.5°W - LyngSat

Hi somebody told me the icecrypt s1600 would do the job but apparently the manufacturer has gone bust. Looked on Internet and suggested techno mate tm5402, anyone have thoughts on that.

Whatever receiver you do settle upon, it needs to be able to cope with Symbol Rates in excess of 40000.

If you do a Forum Search, there is a humungously long thread about 27.5W.

Second time of writing:
Looking at the original thread heading I realize we seem to have gone off track somewhat. The best plug and go box at the moment, (and I fit a lot) is the Edision Picco s2. There is a fully loaded channel list and BBC works without any messing. I normally delete everything exept the BBC from Organising Services dropdown. Also cheap as chips.
You will need an 80cm dish in Spain / Portugal

Hi handy Andy thanks for your advice. So will this receiver accept the BISS encryption codes needed to watch
English channels on Intel sat 907 27.5 w. Many thanks Martin

From something Ive seen this evening it seems the BBC are now feeding most of the UK tx sites by fibre. That will inevitably spell the end for 27.5W once the rollout is finished. So make the most of it whilst you still have the chance.

Doesn't affect my turnover. There's still plenty of inaccessible places in UK that will have to be maintained.

I would have thought they may keep the satellite link as a back up, it only takes one careless contractor to dig in the wrong place to take a major fibre link down.

None of the Freeview transmitters take this satellite feed as their main programme feed.

There are more fibre-fed transmitters now, but still a majority of relay transmitters are fed by the off-air signal from their parent transmitter.

The back-up on 27.5°W is there for in case the main programme feed for the transmitter fails (e.g the reception of the parent transmitter is wiped out by weather-related interference, or the fibre feed fails for whatever reason). It doesn’t carry all the regional variations needed to be the main feed for anywhere.

Edit - You can see which transmitters have been taking the 27.5°W feed recently here. Any faults reported as "Wrong region" will be ones where it fell back to the satellite service (which only has regionalisation for Wales/Scotland/NI on BBC One SD and none of the other channels).

I still predict that 27.5W will be turned off sooner or later.

1) there is enough backup capacity at 28E for one bird to fail completely and the major channels to be switched over to one of the other birds. It might take some major swapping around of frequencies but whatever disaster recovery plans SES have will have just this scenario in them.

2) BBC funding is reducing rapidly and 27.5W is a luxury when 28E is resilent enough to be used instead

3) Fibre penetration is improving all the time and lets be honest - short of the local farmer sticking his backhoe through the cable its pretty robust

Ergo slew the relay receive dishes round to 28E & shut the Intelsat uplink down

It wouldn’t be possible to use the existing feeds on 28.2°E though.

The way this system works is that the channels on 27.5°W are encoded in such a way that they can be piped into the digital terrestrial modulators at the transmitters when the main feed fails without any re-encoding of the data.

The maximum bitrate of the Freeview SD multiplex is around 24Mbps. All of the SD channels + radio stations, including one of the 4 BBC One SD versions, will never have a combined data rate of more than that 24Mbps. The Freeview HD multiplex has a maximum bitrate of around 40Mbps, and sure enough - the HD channels combined from 27.5°W never exceed this data rate.

You’d need another transponder in exactly the same way as 27.5°W currently works if you were to move it all over to 28.2°E. Presumably capacity on 27.5°W is cheaper!

Basically -

Using 1 transponder with all the channels packaged ready for digital terrestrial transmission (a la 27.5°W) = pretty cost effective
Receiving the various required channels from a number of different transponders, re-encoding them to match the different bitrate constraints and reassambling them into the two digital terrestrial multiplexes (if using the current 28.2°E feeds) = complex and expensive and on top of that the picture quality would be dreadful.

Granted, fibre is getting cheaper, but these are used as a backup at some of the most isolated transmitter sites.

It’s all a similar concept to the multistream transponders used to feed Italian/French/etc digital terrestrial - the data is all in the right format for digital terrestrial already. All the transmitter has to do is modulate a terrestrial signal without touching the programme (video, audio, EPG, etc) data at all.

How lucky we still have, as continental Europeans,there are UK regions that need this transmitter at 27.5W!"The misfortune" of those in these regions is a great luck for us.Thank goodness,Brexit is still not valid on Clarke's arc :)

I thought Gibraltar TV was fed through Fibre? 27.5w is used in case the microwave links between transmitters go down

i second that, remember reading about it being fed by fibre on an old site awhile back
