1.1m dish set up

**mick2me** · 11-10-2008

Heres the result of todays work

Peaked Thor

Sent dish to other satellites via usals

Scanned them for channels when dish had moved...

y = channels received
n = no channels received

5e y
7e n
10e n
16e n
21.5e n
23.5e n
28.2e n

1w y
4w n
5w y
8w y
11w n
12.5w y (low signal)
15w (1 channel only)
22w n
27.5w n
30w n

In order to get any signal from 28e I had to change the dish elevation (on dish scale) to 28 degrees As opposed to 33.5 degrees with Thor peaked?

If you have to adjust the dish EL to get other satellites then either Latitude is incorrect on motor or something is not plumb. The picture of the motor scale doesn't show any other markings, can you supply a better picture of this?

what is you latitude and longitude as that seems wrong if you have to adjust the dish like that.

33.5 degrees on the dish seems a bit high as mine is around 23-24 degrees, thats with a latitude of 53 for my location

28 degrees is more for a fixed dish as motorised the dish is lower due to the motor elevation

**rolfw** · 11-10-2008

Check which scale you are using, that looks like the elevation scale and even if it isn't, unless your motor is significantly different from mine, the scale runs from left to right, that would make your reading 57.5 degrees not 52,5.

**mick2me** · 11-10-2008

Heres the full view of the motor latitude scale.
It was half a degree out but i corrected it to 52.5

**satelliteman** · 11-10-2008

Looks good, nothing wrong there with that setting

**Robbo** · 12-10-2008

Yes, I agree, nothing wrong with the motor setting. It is a bit of a confusion really, as you appear to have done it 'by the book', but still not getting the result. The only thing I can think of at the moment, is to get a 'Wixey angle gauge', firstly to re-check the pole plumbness and secondly to check the top bit of the shaft comimg out of the motor, it should be at an angle of 37.5 degrees with respect to vertical.

**mick2me** · 12-10-2008

The variables that could cause this are AFAIK

Pole not Plumb
Dish not center on motor stub.
Incorrect elevation set on motor
Motor not square on Pole.

All are Ok?

What about problems with the dish or LNB support shaft?

Pole not Plumb... use a string line (plumb line) don't rely on spirit levels or at least always use them both ways to always keep a check on the accuracy of the level's bubble.
Dish not center on motor stub... wouldn't cause that fault anyway... just make all USALS positions out by x degrees..
Incorrect elevation set on motor
Motor not square on Pole.

All are Ok?... can't be

What about problems with the dish or LNB support shaft? Unlikely.. if that's out a bit (they usually are not perfect) it will still work the same for all sats..

Try a string line on the pole and also try it at 1w and then again at 28e.. it could be a PBO fault.. pole bending over (or movement on the anchors)

did you need to raise the elevation to get 28e or lower it...?

Just noticed your n y's on the satellites .. thought you'd got all listed ... you need to go through it all again step by step.. also.. is there anything in the way... trees etc?

He had to lower the elevation Pedro.

I have never had a problem tracking the arc, but I would assume that if there was PBO then the dish elevation would need to be raised at 28E not lowered?

A good tip though, I have taken note of that one, i.e to check the pole is still level when the dish is moved round.

**mick2me** · 12-10-2008

I decided rather than check the pole, which I had already checked as Plumb, that I would put a spirit level on the motor.

The first image is the square against the back of the motor.
The second is on the right side of the motor (a Nat's Co*k out perhaps)

Then I drove the motor to its central position. The motor stub should then be Vertical?

I then checked the vertical on the Dish.

The result can be seen from image 3!

There is no further adjustment of the dish bracket on the motor stub.

What do you think now?

**satelliteman** · 12-10-2008

You just need to make sure the pole between the T&K brackets is straight all the way round.

**mick2me** · 12-10-2008

Yes The pole is Plumb. I checked the motor bracket thats sqare in both directions.

But with the motor stub centred the Motor stub(and the Dish) is not Plumb?

There have been some Moteck 2100 clones that have had bent motor arms.

If you set your location in your stb to zero east/west and send the motor to zero (just alter Thor to zero for now) ... does the motor go to exactly zero?

Set Thor to 0.0
set my location to w0.0/n52.5

Sent dish to Thor

Motor scale show about 10w with dish tilting slightly west.

As above post when I manually drive motor to centre position.
the stub (and dish) is about 5 degrees west. I have to drive it
about 5 degrees east get the bubble to centre on the spirit level.

Maybe there is an adjustment for this?
(I can see what looks like 2 allen screws)
The motor is Geotrack H120

pedro2000uk · 13-10-2008

OK... go into Diseqc 1.2... use the controls to nudge the motor to ZERO on the motor's dial... you should have an option to recalculate - that should re zero your motor. Then check it again by go to reference or going back to USALS and with your settings & Thor still zero.. check Thor is zero .. (go to 5e then back to Thor just to make sure)... all the satellites will be at the right position on the motor dial so you can double check a few of them .. Try 13e does = 13e etc... (they wont work like that so don't expect any signals).

If that is OK then return your longitude to the correct one and Thor back to .8w. Then choose Thor again and line your dish up again* on Thor moving the whole assembly on the main pole and the dish up and down but do not alter anything else (your motor dial should show about 2e ….* make sure you have corrected latitude setting on your motor... and also that all the transponders or channels you use to locate each satellite are active ones.. see strongest signals list elsewhere on this forum)..

**mick2me** · 13-10-2008

I have 2 receivers here and tried what you have said, it still goes to around 10w on the motor for thor 0.8w, when I am 1.2w?

I have now confused myself so much, I cant find where I found the setting to set thor to 0.0.

Having spent most of a week on this, it might be easier to buy a freeview box from ASDA!

I'm going to have some lunch now and go off to work. Might try again in the morning...

Anyway, your motor is out about 10 degrees westward .. the docs on the Passion might give you a reset (motor) option too.

Also, I think other things are at fault too ... there are quite a number of things to get right and if something is faulty too it really can through everything out.

**mick2me** · 13-10-2008

Currently workig with a Fortec 5100

And I have checked both sides with level

Bubble is fine on the level

I have another motor, If I can get help tomorrow I will get the dish down and change it.

No problem with PBO on these brackets

**satelliteman** · 13-10-2008

Change the motor and see, it may be duff

pedro2000uk · 14-10-2008

The weight of a heavy 1m /1.1m dish like a Triax or Channel Masters can cause faults or show up faults/weakness on some diseqc motors that would normally work OK on slightly smaller/ lighter dishes.
With heavier dishes you soon find out what motors are up to the job. That might not be what's up... just another possibility- if it is that, whatever sat you send the motor to can be out.

Does the motor make any unusual noise.. particularly from far east or far west positions moving back to zero?

**mick2me** · 14-10-2008

Moves smoothly from east to west?

pedro2000uk · 14-10-2008

That sounds promising, at least it's not grinding, smoking, bits flying out etc... (I hate it when they do that) as to the 10 degrees out .. it may have slipped previously under the weight 'plus' a strong gust of wind....or er... not.

When you get it off, check it all and set it up on the floor and reset it there if it will reset.

**mick2me** · 15-10-2008

Motor exchanged.

Tuned to Thor

Moved to 28e but still needs dish elevation changing to get a signal?

Its the elevation thats wrong somewhere. East to west movement takes it to the right E-W

RAIN STOPPED PLAY...

post some pictures, it might be something obvious
