We experienced very strong winds during the last few days and lost everything on Astra 28.2. Just been out there trying to get it all back and can not find Astra at all. Have we lost it over here in Murcia?.
Any reports?

 

[woborny]

Everything is working fine here...

 

[Juan69]

You are quite a bit north of me. Just seems strange to me that I can not find the sat at all. I have to go out, I´ll have another look tomorrow. Thanks Woborny

 

[woborny]

Well dont forget you have 5 satellites to aim for - 1n, 2a, 2b, 2f, eutelsat 28a
So unless you have a cable / lnb / receiver issue or failure, you should be able to get a signal from one of them...

No, it works fine. I fitted a 1.4m dish down there last night. Plenty of signal.

 

[Juan69]

I can get Hotbird, Eutelsat and Astra 19. Just not 28.2. I´ll have another go tomorrow. Thank you.

Astra 2F Report (from a dish i installed ) in Ocana , 60km South Madrid 1.2m tecatel with a noname reciever and lnb that cost 2 euros .. all stations recievable and stable in heavy rain. Cant test late at night as its a commerical location with no access.

I was really surprised at how even fine adjustments make a difference between reception and nothing, felt like millimeters.

 

[Juan69]

How do you do the fine adjustments? By the way have you tried the wine in the Almorox co-operative?.

 

[davidcmadrid]

Juan there are far better guides than i could give you regarding dish orientation here . However nudging the dish slightly had an impact and i do mean slightly ,, also tightening the bolts holding the dish onto the pole assymetrically had an impact ie if i tightened one side without alternating to tightening the other side it was enough to effect the signal reading ( dish heading ) . The one mistake I can tell you i made is randomly moving the dish about " more or less " where I thought the satteltite ought to be , i found it better to set the elevation and skew and them move the dish left right methodically ( moving elevation on each sweep ) whilst tuned to a 1N frequency ( strongest ) and then fine tuning for 11023H ( relatively weakest here in Madrid and many parts ). Dishpointer.com is a good start to give you the information about where the dish is in regards to you. I dont drink alcohol in answer to your other question.

 

[Huevos]

Juan, where in Murcia are you?

After the 2F changeover have lost all channel 5s(10964) for most of the day, 4/7 (11127) and itvs (11052) both watchable.
SQs are 45% for C5 and
60-65% for the others.
Signal levels not posted as my rubbish digital 1200CI reported signal levels are a work of fiction as signal levels of 69 may not lock but levels of 60 may. I cannot touch the dish until after new year through fear of divorce as all other channels have qualitys of 85-95% and are watchable 24/7.
I will have a tinker then unless more moves take place before christmas, any recommendations for a cheap (sub €100) sensitive hd receiver would be appreciated.

Just had a tweek after xmas and no further improvement possible, will hang on until 2E rears its ugly head and see what happens as exchange rate stuffing my pension at the moment so saving my pennies for other things.

Common sense lasted about 3 days, skybox f3 on the way from amazon for about 55 quid, it may pay dividends if I have to point my dish elsewhere in the future. Now have to wait 4-7 days for delivery. Will post levels for the 2f transponders when it arrives, christmas came very early this year

Mine's got stabilizers too. It's a bit of a long story. I found if I pushed up on the LNB arm the SNR improved, but if I loosened the dish and realigned I couldn't replicate the improvement. This could only mean one thing, pushing up on the LNB arm was deforming the dish slightly, so I added a stressor to hold it in this position. Gained about 0.5 dB SNR, which is a lot when you're on the reception limit.

The 3 numbers is pretty simple, and only an indication. Say your signal on 1N is 70dBuV and only 60dBuV on 2F that is a difference of 10dB. No lock on 2F. So look at C/N on 1N. Let's say C/N on 1N with your 1.5m dish is 15dB. You need at least 8dB to lock these transponders properly so you are 7dB above lock (15dB - 8dB = 7d. The difference between 2F and 1N was 10dB, so, all things being equal, you need to pick up 3dB (10dB - 7dB = 3d to get lock on 2F. Translated into dish size that 3dB is 2 to 3 increments. Each increment in dish size will pick up 1-1.5dB in C/N. Increments something like this: 80cm, 1m, 1.2m, 1.5m, 1.8m, 2.1m, 2.4m, etc. This should get you some sort of ballpark figure.

Hi again I am sorry for the delay in replying I had to go back to the UK again very ill relative.

Some results to look at.

1.5 with black ultra 10773 Dbuv 83 C/N 13.4, 10964 Dbuv 68

1 mtr motorised with Octo 10773 Dbuv 71 C/N 10.2

Test on a friends Triax 1.1 with Lemon twin Lnb 10773 Dbuv 75 C/n 10.8

Working from the rough calculations I think on the results from the 2 smaller dishes that roughly a 3 mtr dish required however with the 1.5 it would suggest arround 4 mtr.

So I think I have a problem with the 1.5, I purchased it second hand and I am thinking it might be distorted.

However I have just noticed that since I came over in November one of my neighbour's in typical Spanish style has had a new Ariel installed on the chimney on a 2 storey house on a very long pole waving about in the wind, this falls direct centre of the 1.5 so could be slightly blocking signal, need to do some calculations.

I will remount the 1.25 on the motorised pole to get another reading.

Anyway sorry for the long post nml

Thank you David. It has been driving me up the wall and have decided to stop for a while as it was taking over my life and patience was running short. My excuse for now is the high winds. I´ll have another go next week as you suggest.

Juan, where in Murcia are you?

Huevos, sorry for not getting back here earlier. I am 20 clicks north of Murcia.

Ok we have a new map to populate - lets see what the new beam is looking like.

To begin with we will start with Sky News SD on Sky EPG 501, Freesat epg 202 & frequency 12207V 27500 2/3

Cartoonito or Fox SD Sky UK epgs 619 & 188 (12110H 27500 2/3)

As before we want positive & negative reports, dish sizes receiver &and lnb info

Your location is vital for this - the nearest town to you

An idea of the reception would be very useful - for example

no problems, good signal 24/7
no signal since the move
poor in the evening good in the morning

Ciutadella de Menorca - 120 x 130 offset with Grundig quad LNB.

Have just checked Sky EPG 188, 501 & 619. Good signal strength and quality on all three as seen on my Amstrad 890 Sky+ HD receiver.

By the way, EPG 188 is Fox HD not SD as you've indicated above.
