Help Required 1m motorised install

[gdf68]

Yes 28.2 yes 39.0e
42.0 no 52.0 no I used to get 52.e

Sorry 36 was a mistake but I do get some. I went to 36 instead of 39.e on the meter.

It appears that your arc may be either too shallow or too acute, best way to find out is to tilt the dish with your hands while watching the meter signal when on the most extreme visible sat. If the signal improves when tilting the dish upwards, then the arc is too acute and if better when tilting down, too shallow, so the motor declination setting will need adjusting.

When you are OK at west, but not OK at east, I'd first check if the due south is correct.
Are you using usals?
Did you electrically rotate the motor axis to 0.8W, before finetuning at due south?


To add:

For finetuning I use these drawings: http://jackysat.atspace.com/obrazy/max/korekcija.gif
Start with C and D, and only when that is OK, check A and B. And then repeat these steps.

Interesting read that disaster thread, I tried the hand method of tilting the top and bottom of the dish but no signal .

I may have inadvertently forgot to makee sure the motor was at zero before I sent it to 1w via the receiver.

When you say due south you mean I haven't got the motor plumb due south

When you say due south you mean I haven't got the motor plumb due south

The motor zero and due south should be exactly in line.
That leads to left and right symmetrical following of the arc (as it should be).
And after that is set correctly, you can check if elevation and declination are set at the right balance.

'Plumbness' of the pole (needed in east/west direction!) is something different.

So I don't know if I understand your question correctly?

I put the motor on the mast pole first as too heavy doing motor and dish in one.
Then lined up the dish centre to centre on motor.

Moved to 0.8w receiver and then moved eas west whole unit until max signal for 1w same for 30w and 39.e

The due south is correct bit always gets me

Just to add with USALS you no longer have to worry about due south as long as motor is at 0 and you then rotate rig as you did. And you had everything in line. Also with USALS you can use any satellite to peak single.

Techincally you could but I would argue that you should still use the satellite highest receivable at your location to do the initial alignment on, which is 0.8W in most of the UK. Further west, satellites at 3W and 4W may be more appropriate (I use Amos@4W as my longitude is 2.7W).

Thanks guys, not been up yet. I'll loosen up send back to 0 , centre line up every thing and go again. Next week at this rate , probably be another storm by then.

You have me confused, I thought you were sorted!! The best method for you is 0.8W and use 2 fta channels , one for H and other V. I use Aljazeera and Galaxy. The best signal ref is a picture. What receiver, image, dish size, lnb, cable and motor and image = a realistic signal level. VIX is very high, Openatv can be low and so on. And having LNB at correct focal length ie move in and out. The most important bit is everything dead straight. But if you get a figure in the 90's for the 2 channels you are dead on for all sats unless trees, etc in way .

 

[gdf68]

No, my last comment on 13th was what I did on the 12 Jan and I was not getting all the arc 42e and 52e, 30w was 70s as was 0.8w

I haven't been back up to double check alignment.

Ok read the lot so got a full grasp. I take it you cant stand on flat roof but if you could would be helpful. 15 years is a long time. Could be time for a new LNB!! What receiver are you using? The idea of motorised is to do 0.8w to the max, tighten up and try each sat on EAST and WEST. I have a Triax 1.1M a dark motor, and DUO2 and OpenVix Image 6.4 to drive the dish, with a black ultra LNB QUAD and very good cable. 16 years and I did change lnb once. My method was to use a receiver that gave signal via scart and a portable TV. Would sit on roof and tune in to 2 channels on 0.8W as above. Get the highest possible signal and I would move dish side to side, ie loose on motor. BUT I have to admit everything was plumb from the outset and even put level on bracket bolts. I followed the 3 dots ie aim like a gun, here is a pic and I would would move lnb in and out to get exact focal length. Took about 3 hours for the lot.

The dish on the stub can be offline ever so slightly and difficult to spot. At the moment I get 100 on galaxy and 95 on Aljazeera. I'm at 8 west near Atlantic.

You can tweak USALS from the receiver but you cant save the settings, say box and image and I can guide you. You can step the dish/motor and if signal goes up etc.

Here is a pic of my LNB and note this is at correct focal length. Say channel on 16e that you want and I'll check. Needless to say I'm not busy today!!

Thanks , got some PF100 for another project, so connected up the Xtrend 8500 open vix , twin GMedia 202 lnb.
0.8w
Galaxy 76%14db ,sky news 82%db15,,
fine tuned moved it in signal positioner a few steps west and got it to go 82 and 88.
So up the ladder and used the old method of the other half shouting the readings, she hates me getting in the flat roof, since we got it all replaced . I didn't have time to go through the whole arc. BBC 1NW was 100% on 28.2
39.e , 42e 30w in the 80's
Nice clear day here in Liverpool today ( windy)

I'll check 16.e later for a channel.
Darts is on ,

52e nothing still only difference to last June setup is the whole rig is slightly lower on the scaffold pole ,(few inches). So may be not visible?

I understand different receivers, tuners, SW images , cable lnb can give different signals. GT media8 readings are 70's

I was thinking of getting a 1.1m dish but not sure how much of an increase I would get , that said here in NW 2.971w should my 1m be getting higher in 0.8w?

That's good and can you just check the lnb, there are 2 versions, don't ask!, the better one is the 202 + one, see pic. Now that you are set up you can sit on the sofa and give usals a little tweak while you are on 0.8west I use Galaxy/Al Jazeera for the other one. There are 2 ways to tweak from the couch. 1. Go to USALS in the receiver and either decrease or increase the longitude figure is small steps. I think where you are it will be something like this 000.858 so try 000.900 and so on, its slow as you have to exit and see signal. 2. This one is better BUT I only use the step function and don't touch anything else!! Go menu setup tuners/scannng, down to positioner setu, then arrow down to fine movement, look at bottom of screen and see green to go east, yellow west,. While on say Galaxy tweak either east/west a few times. I usallly go until I loose signal. But you figures above are good. A 1.1m triax would be a tad better but if lnb is not the + I'd try that first.

I had a look just now on sky news and galaxy , sky news 87-90 and galaxy 98-100 but I often find H is better than V. And yes 53 east too low for me.
