RTE Announce FTA Saorsat service

A manchester guy tested the signal and confirmed it was DVB-S with no data, hence a deliberate jamming carrier.

It's only 'hence' if there is nothing else on the frequency.

Are you saying that Tooway do not have any customers using 9E in northern Scotland?

They are certainly selling the service there.

Why would they need to put on anything in addition to the satellite internet service which is the primary purpose of the satellite?

I would suggest the reason they have chosen to not use an internet carrier at the exact same position is

1) An internet carrier may not work as well to jam as it may be lower power or wider.

2) An internet carrier may get interference from the Saorsat signal, which may degrade the internet performance. In theory this should not happen, but in practice the spots are not really as clearly defined. For highest speed internet ideally you would try not to re-use the frequencies again nearby if at all possible.

3) With a non internet jamming signal they can make it narrow, and adjust the relative power of each to try and just cover the area needed.

Below is the spectrum as picked up in Manchester:


The only one we are interested in is purple 20.185 Saorsat, however it can be seen all 4 spots have 2 internet carriers (wide ones) while the purple also has one narrow one, which was measured as a DVB-S blank carrier using specialised equipment.


Above as picked up near London



and finally as picked up in Dublin. The narrowness of the signal is clearest in the more expensive test equipment. It does seem as if some of the french spots have 4 carriers (to have more capacity) while the Irish and east Scottish beam only has two internet carriers at present. Even on the french system there seems a suspicious gap between the two carriers like one was meant to jam Saorsat.

I would suspect in general they try to seperate internet carriers frequencies slightly, much in the same way as analogue TV transmitters that may be on the same frequency are normally adjusted slightly higher or lower than other transmitters to try reduce interference. Also circular polarisation even does not block the opposite polarisation completely so the blue beam will effect the purple beam too.

got soarsat and sky working on the one dish, needs some adjusting but as it was very windy last weekend.

Getting only 23 percent signal quality though on soarsat , location achill island.

There is a Saorview mast on Achill Island (CH47 Vertical). Any particular reason for attempting SaorSAT reception?

There must be somebody out there that knows if tv3 is coming on saorsat. soarsat seems to be one of the best kept secret in Ireland as it was never mentioned on any of the saorview ads.The only place any information is available is here on boards.ie.

and on www.saortv.info

Will be updated with more on Freeview, Freesat, Free European mainland satellite TV and PVRs when new hosting found.

1.2m Channel Master dish.

If it is a fibreglass dish then it may not work as well as a solid dish. Fibreglass dishes generally use a wire mesh type design, and the mesh size may be too large for the 20Ghz Saorsat signal. You may find a smaller solid dish may work just as good if not better.

John from "swansea" said he received Saorsat with 90% quality on a 2.4M dish. As reported on digital spy

so Swansea should be OK

does this mean RTE will be available FTA across europe??

This what the then RTÉ CFO Conor Hayes said about Saorsat back in July 2010 to an Oireachtas Committee when it was first announced - http://www.boards.ie/vbulletin/showthread.php?p=78496839
