Dish alignment - can only find Astra 1 but want Astr 2!
Steve
I'm having problems aligning my new dish and wondered if anyone can advise.
I get very strong signals from Astra 1F at 19.2E and Astra 1E at 23.5E with
the same dish position - loads of channels. Signal strength and quality are
about 80% for both 1F and 1E.
But I want 'Astra 2' at 28.2E and can't find it. My satellite-finder meter
give a very strong signal for the Astra 1s but reducing the elevation and
going east a few degrees gives only a weak signal the receiver doesn't
recognise.
A couple of questions occur to me:
1. When I point the dish at the Astra 1s, the dish is vertical, as the
offset angle equals the elevation (about 24deg). Astra 2 has a smaller
elevation so I have to point the dish downwards and I get a lot background
radiation from the garage roof when the dish is pointing downwards. Could
this mask Astra 2? If so I'd have to raise the dish's height or change it
for one with a smaller offset angle. Aargh.
2 Is Astra 2's signal strength a lot weaker than Astra 1s? So should I be
looking for a much weaker signal than my meter gives for the Astra 1s? With
the Astra1s, the signal is so strong that the meter is off the scale even
with the sensitivity fully down.
For information I'm in the UK (Devon) which is Zone 1. I have a new 60cm
dish and a new Labgear DV3 receiver.
Suggestions gratefully received.

It is there!

It is not a lot downwards....

Yes.

If the thing is in the way, then yes.

Actually Astra2 is stronger here, could be alignment though.

Should be enough for Astra.

You need a clear line of sight free from obstructions to the
satellite.
As you are first timer, you'll probably find it useful to read the DIY
instructions linked from the Satellite TV section of my site, dipping
into the Analysis pages as need or fancy dictates. The Settings
Analysis in particular may prove useful for DIYers.

Is the receiver tuned in to a frequency corresponding to a Astra 2
transponder ?
If not, your satellite-finder won' t see anything.
The same thing happened to me once.

a bit rusty here,as the US systems differ a minute amount! Way back
when I was capable of giving all the answers I was an avid DTV pirate!
Then the heat got soo bad I went to FTA/DVB. Now for the last 3years
all I have been required to do was reload programs or change keys
periotically and have forgotten most procedure!
However to compare your situation to what I was used to leaves me
puzzled!! With a single LNB on a round dish there was only one focal
point! The lnb was not open enough to get an adequate signal from two
sats over 3 degrees apart!! Which makes me wonder if your dish is
warped to allow two focal points??
The reflection of the garage should not be a factor unless it is with
in the line of site! However the roof can also produce a reflection
that maybe coupling a transformer's RF that could overide your
intended sats signal!
Soo look the situation over for obsticles that could create a false
focal point or blockage! Maybe moving the dish location is your
answer??
I'de check into an h-h motor so as not to loose what you already have!!

Thanks for the helpful comments everyone. Plenty of food for though there!
I'll let you know what happens if I sort it out.

I assume you've bought the Screwfix dish/receiver set. I bought that
recently, and with the help of Java Jive and others got it set up OK Astra 2
(satellite reception was completely new to me too).
What I can't understand is how you are getting decent signals in one dish
position from two satellites several degrees apart. When I was slightly
misaligned on Eurobird 1 at 28.5°, I got poor results from Astra 2 on 28.2°,
particularly in rain. With a very small adjustment I got good signals from
both. All I can say is that the horizontal and vertical positioning was
critical. Even tightening the fixing nuts too much caused some misalignment
(I did not use the wall-mount supplied, but used the TV mast), and in the
end I decided to tighten each one of them one turn at a time. Probably
wasn't necessary, but it worked.
Hope you get it sorted - it isn't a bad receiver if you are trying things
out.

Thanks to everyone. If anyone is still reading this thread, the problem is
now solved.
When I got the receiver it was pre-loaded with the transponder data
(frequencies etc.) for a wide range of satellites. But some were completely
wrong - the pre-loaded Astra 1 transponder data (for both 19.2E and 23.5E)
were in fact the Astra 2 data!!! This is how I apparently could pick up 2
satellites at once - I was actually picking up the Astra 2 transponmders all
along, but the receiver falsely identified some as Astra1E (23.5) and some
as Astra 1F(19.2). The Astra 2 data was all wrong.
With the correct transponder data against the correct satellite description,
it now works a treat.
Thanks again.

Sounds as if I was right !

Steve, I've been following this thread with interest as I seem to have a
similar problem.
Could you tell me how you rectified it? How did you get rid of the
pre-set information and retune it?
Thanks,
Mr. Crabtree

Yep,You are the man!
I always use blind scan (pansat 2800)soo tunning to a specific TP was
the last thing on my mind!

Hi.Mr Crabtree
You can find out each satellite's transponders details from a website such
as www.lyngsat.com. My receiver displays the data in its database (which
was incorrect) via the Installation menu. I had the wrong transponder data
loaded in the receiver, but heaven knows how/why, as it was new. It's
worth looking up the data to start with, to see if that's the problem.
I fixed the problem by using the 'Factory Settings' menu option. I'm not
sure precisely what got changed, but the right transponders were then
matched to the right satellites.
A couple of other options are available, as I understand:
If you do a 'blind search' with the right settings (start and end
frequencies and other things) I believe the receiver scans all frequencies
looking for transponder signals. These are then added into the receiver's
database.
My receiver also has menu options to delete transponders and to add new ones
(you need frequencies, polarisation and symbol rate for each new
transponder). These would be manually entered into the receiver using the
'add transponder' menu option. You would manually delete incorrect
transponder data using the 'delete transponder' option.
I expect your receiver has different setup options, but the principles would
be the same.
Hope that helps.

Many thanks. Sorted!

I have found out that lyngesat can only advertise the legal aspects
and cant direct you where you realy want to go!
An example if providers change transponders for a PPV just before an
event,the only way you can see it is a fresh scan of ACTIVE
transponders! Lyngesat cant even tell you about a scan! Soo bare in
mind lyngesat is paid for by the providers$$$$$$$$$$$$$$$$$
