Hi all need a bit of advice ,from channel 101 to channel 125 signal and quality strength 100 percent then any channel above the quality starts to deteriorate to below 70 percent have i got a problem someware,checked all connections and both cables and dish alignment all seems ok. Is it possible to get 100 percent signal and quality on all channels.

What do you have on CBS action?

strength 90 quality 40 on both tuners

Sounds as if your dish is slightly out of alignment with the Eurobird 1 satellite but ok with the Astras.

I agree 40% is very low. Most of mine are 100/100 a few EB1 transponders are 90/90. EB1 needs a different skew to Astra 2 so a comprimise is needed. With 40% you are going to get signal drop out in adverse weather. Not mention problems with the Freesat home transponder also on EB1.

Hi I am a bit confused does freesat use two satellites to recieve all channels I thought they all came from astra

Positions are 28,2E for the Astra group and 28.5E for EuroBird 1- I would guess that are pointing at less than 28.2E.

My CBS action is just above yours - but I have a distance problem as well. (also suspect the bit rate on CBS action is not very good)

Currently channels on the freesat epg come from Eutelsats Eurobird 1 at 28.5E, and 3 SES-Astra satellites at 28.5, Astra 2A, 2B and 2D. Later today a 4th satellite is due to be launched to join the 3 at 28.2E (Astra 1N).

Freesats epg, ota updates and other services come from the freesat transponder on EB1. Thats what you are using when you enter a postcode during setup.

Click on the link here for a list of current freesat channels sorted by transponder (the satellite source is identified).

If you choose one from each transponder in turn and use Menu/System/Diagnostics to find sig strength/quality (make a note). Either post the results to see if there's a correlation between Satellite and/or polarisation (H/V - Horizontal/Vertical) or have a look yourself.

If you have totally missing transponders it may be down to local interference.

All the free to air channels from here can be viewed using non-freesat mode (many not on the freesat epg).

Sadly Graham your Last Link says over a dozen times and high-lighted that ..

Eurobird is at 28.2E

I know you will soon sort someone out.

Look again Stan.

Typo, its Astra at 28.5E is the error. EB1 is at 28.5E always has been.

In fact the locations are approximate, you can't orbit multiple satelittes at the same orbital location, they would bang into each other . They are seperated enough to allow the orbital positioning adjustment to avoid collision. On a smallish dish the seperation is pretty irrelevant because of the wide angle of view. Get a 4M dish and align it on EB1 at 28.5E you won't get Astra 2 at 28.2E just like the narrow angle of view you get from a high power telescope, or more accurately a large mirrored reflecting telescope which works with light identically to a dish receiving microwave rf from a satellite.

Terrestrial antenna work the same, a high gain antenna has a narrow forward gain envelope requiring a more accurate alignment. You don't get something for nothing. Example If you erect a vertical half wave dipole you get the same (low) gain from all directions. Add parasitic elements like directors and reflectors you focus the the direction from which the antenna can receive increasing the gain. The more elements the narrower the acceptance angle. Another comprimise here (sadly like everthing in life), the wider the range of frequency the aerial has to recieve the lower the gain. That's why wideband aerial have lower gain than antenna designed to work with a smaller part of the rf spectrum.

I lose all my EB1 channels during the summer as a tree comes into leaf and partially blocks the signal. My strength and quality is also reduced on Astra channels but still high enough to have no problems. It's not a major issue, except Freesat updates, channel changes, etc don't update. On windy days I can just get a signal - recently I did a scan to pick up the BBC HD channel changes. I don't know if realigning the dish would help - in the winter the strength and quality is 90-100% on most channels.

EB1 uses the higher frequency band than Astra 2d and also they are normally a bit weaker. Leaves are a killer for both terrestrial and satellite and the higher the frequency (the shorter the wavelength the more the attenuation). Sadly I imagine there are only a few solutions,

Favourite - A Chain Saw or more impractable - Agent Orange,

More practical - moving the dish location, you might find a spot with a better signal. You need a proper pro fitter with the right kit to pursue this option.

Thought i'd lost some of me marbles then.. BUT
I've looked again and all Astras and Earlybird are listed umpteen times in Bold and in the Sharpest contrast ratio known..
viz Yellow and Black
precisely as i said before at 28.2E..

Stan
PS Just seen that G has confirmed this and pointed out that the many errors are in fact relative to Astra birds.

Many errors ?. One digit In my post there is one error SES Astra should have said 28.2 not 28.5 thats a single character. What do you think are the other errors ?

Not sure what your post means

Currently watching 1N launch live. Countdown currently held at T -7 minutes,

I never meant or implied in YOUR post G.. i said ..
..
the LAST LINK in your post..

the one that gets you to a huge list of all the stations available.....where the umpteen repeated errors may have been for ages un-noticed..It does happen..

I accept it is an irritating facility from a Newbie which arises because i was sent on a Proof-Reading course once..

Stan

It's very common to quote 28.2 and 28.5E as one orbital point because for UK viewers using less than a gargantuan dish they are. The figures are rounded to the nearest 1 decimal place.In reality if i remember correctly they are kept within a 50KM cube, if they stray their position is corrected by a short propellant burn. Experts on here will know the real numbers.

Even the pressure of photons from the sun marginally effects the orbit location during the period the satelitte can see the sun.

The Link itself has been most useful.. as with over 50 years of setting up Astro Telescopes ..
i like to think that our Dish is finger tipped to perfection at 28.2..
Positioned deliberately on top of Porch roof.. allbeit at extra Coax length penalty.
In fact at the moment the Quality of all the Astra channels are at 100%..and they are all on 28.2 as it happens..
However the Early Bird quality on 999 is a lousy 60%..
which is not unexpected as the Link shows the Bird way out at 28.8..
Luckily the channels which are then suspect are not on our viewing list ..

I would have thought perfection is 28.35. At my location I can see the difference between them on http://www.dishpointer.com/ - As GT pointed out the LNB shew is different as well.

Ta.. another link added to my FAVS..I've settled for the Astra Skew..

On EB1 you do need to ensure a good signal on the freesat transponder (Channel 999) or the HDR will act up.

Hi had a play with dish today managed to improve strength and quality signal but only on channels that use the vertical signal, its the ones on horizontal are still poor ,any ideas, thanks

Yes did you try adjusting the lnb skew( twisting the lnb in its housing). A skew setting thats not optimal will favour horizontal or vertical polarised transponders over the over.

I have two Foxsat PVR's. One worked perfectly well until recently when the BBC HD channels dropped out. The other was never able to record and view another channel at the same time. I always put this down to an ever growing sycamore tree interfering with the signal.

It doesn't interfere with ITV HD or Ch4 HD

I suspect that your second HDR is in single LNB mode.
Check the firmware versions on both your HDR's they should be at 1.00.15. You do leave them in standby at night?
