transponder problems

[dabba1]

HI

I have just set up a system, just basic to play with.
I think I have the astra cluster. however the transponder frequencies are strange !!!
on lyngsat true movies for example are on 11642 V 27500 , however I have it on 11642 H 27490, and this I have accross all my cahnnels .
the polorization seems to differ !!! Sky news on 12206 H 27490 on lyngsat it should be 12207 V 27500


also there are a number of channels i cannot reciever .. horror movies 4 men etc

what am I doing wrong.

I seem to be getting astra south beams and some Eurobird channels but with wrong transponder polorization

any help would be appriciated .

One of my Receivers has FTA and Scrambled interchanged in the scan menus.

Bad software!

It's quite possible the H and V are interchanged for similar reasons. If so, it's a foible you can live with.

As for the Symbol Rates, don't worry: Scanning rarely brings in 22000, 27500 exactly, but it matters not a jot. Ditto with Transponder centre frequencies.

Anyway, please tell us more about your system: Location, Dish type and size, LNB type (Is it a Fortec Star FSKUVN?), and especially Receiver details.

hi

yes the reciever is a fortec star !! not sure of model i will take a look and post ..

the dish is a kit 1m set up to play with .. nothing special . but also confused as to why i cannot recieve some channels ! whilst getting some (good signal )on the eurobird 1, also astra 2b & 2a south beams, the missing channels seem to be from the eurobird ! (movies 4 men, horror etc) and am not sure if the problem is to do with the transponder polarization !!

I have tried to manually input the frequencies from lyngsat but get no signal on the missing channels!

There is a well known problem with the lnb's in question, you need to read the thread about it and alter the skew accordingly

http://www.satellites.co.uk/satellit...ingle-lnb.html

I know you're confused - that's why I asked for some details.

Can you please tell us the precise model of Receiver, and the make and type of LNB?

Can you please give us a more precise location than "UK"?

Providing these details may help in homing in on the real issue and the likely solution.

However, as the magic words Fortec Star have appeared, you may need to take due note of this Thread http://www.satellites.co.uk/satellit...ghlight=fckuvn which may well have a significant bearing on your problem.

I had less to type, I was often told I am too succinct, I always thought they were being rude

[dabba1]

the reciever is a fs 4300

the lnb is a metronic universal . from a kit .on the box is
freq 10.70-12.75
LO freq 9.75/10.6 ghz
i am in southern spain and i understand the dish size problem.
i would expect to pick up astra south beams which I seem to be doing
and some channels from eurobird 1 although all on wrong polarity

the only obvious thing appears to be the reversed polarity !!

I have 90% signal and 70/71 % quality on what i can recieve but again still reversed polarity .

reading the other post can i overcome this by rotating the lnb 180 degrees?

or is there another way .. the lnb appears to be in the 3.30/ 4 oclock position (using the cable connection as a guide) with 0 on the scale being 6 o clock.

i used the set up info from dish finder

[Analoguesat]

Rotate the lnb 90 degrees (180 will just put the polarities upside down!)

i am in southern spain

But your profile says UK ........ which is precisely why I asked - It is often the case that there is a location related element to Satellite queries.

sorry about that the profile was set up in uk....

i have rotated the lnb after reading the other post and the polarity is now correct. still`problems with recieving channels

is there a unique transponder freq on the eurobird 1 i can use to align to ?

I only hane a analogue needle meter and tone.. although i do recieve the astra channels and some eurobird

thanks

Good result on the skew!

And the Location can be edited easily in your User Control Panel.

As for Eurobird, I think it would be best to use a Fixed Beam TP in the first place and then fine tune using a TP on Steerable 1 Beam, which is probably marginally less strong. TBH, I don't think there's much in it, but that might cause howls of protest and outrage from others in Spain and their input here would be very welcome!

Are you treating Eurobird as a separate Satellite position, distinct from Astra 2, or are you relying upon the fact that your 1m dishes beamwidth is probably such that you can consider 28.2E and 28.5E as one?

PS: If you give an even more precise location than Southern Spain, you might get someone with local knowledge chipping in - Reception in Spain can vary greatly across even a few tens of km!

HI

I am in the Alicante region, which i know is very bad area !!

can pick up a number of other sats no problem and astra south beams.

i am treating the eurobird as its own .. but the signal is weak and but i seem to be getting the steerable transponders, but will check further.

the astra south beams seem vstrong and can pick up no problem when i get eurobird although limited transponders.
the lack of a decent meter prob dont help either!!

any recomendations as to any good ones
time for some fine tuning . and maybe play with some other sats .

thanks for your help

Hi

after some research I have come up with that the missing channels are on the fixed beam transponders F1-4 and C1-6

The LNB setting are for universal in the menu

my signal is 90% on all other transponders and 71% quality including the astra south beams.

looking at the eurobird footprint the fixed does look slightly larger than the steerable !!

so recieving the steerable transponders I would expect to get the fixed!!
I really am at a loss as to why I cannot pick up those transponders, there is not evan the slightest peep of a signal even on the recievers signal meter.

any ideas would be gratfully recieved

[Tivù]

Hmm.

Do you have any "noisy" stuff like DECT phones or Wireless Internet gubbins around the place?

Turn it all off and see if the missing TPs show any signs of life.

[dabba1]

No nothing at all , the most hi tec i got is a DVD player !!!

I would expect to pick up the transponders even on a 60-70cm dish after checking eutlsat website!!

even borrowed another reciever !! no joy !

and given the strenth and quality, (and i know the reciever meters are not accurate but), I would expect some sort of signal even if of poor quality !

some sort of LNB problem perhaps? not picking up specific frequencies? given that it a nasty kit LNB?

Thanks

[Tivù]

Well I honestly don't know.

It is a fact that LNB/Receiver incompatibility does occur (Personal experience!) but the only way you are going to find out is to get another one.

They are very inexpensive and everyone really ought to have a spare anyway.

[dabba1]

Thanks again for your time.

Its all a learning curve I suppose, from my original problem of the incorrect skew using an analog meter !!!

the only thing I can come up with is the LNB .... any sugestions as to a decent LNB ? or how to choose one ?

Everyone has their favourite - mine is the Smart Titanium range.

But it really doesn't matter a great deal - just get one that is of a totally different brand to the one you've got.

I'm surprised no Alicante Members have chipped in ................
