there is a good majority that I dont pull in on that bird.
what about you?

Yes I do need a heavy duty jack as the one i have now struggles around 30w to pull the dish back.

Thanks for the files.

I think my problem lies with my polar mount. The bolts where It tighten`s to the 3" pole are only located at the bottom, as when its slack Its vertical, but when I tighten them it throws the mount out.

I am going to put extra bolts at the top, that should sort it out.

Excellent stuff crossbones. I knew you'd finish this project sooner or later

Monster dish. Well done m8!

So hows is the dish going is all still working ok

[crossbones]

Im going to have to take it down. As there is allot of play in the mount.

And its not sitting plumb on the pole, so its not 100% vertical.

Im pulling in show time on 7w but its got allot of break up

Wow your only about 50 miles west from me it goes to show just how much the signal from nilesat drops in a short distance,

Do you receive any of the orbit transponders on eurobird 2 at 25.5 east just a touch to the right of arabsat 26e FlySat Orbit Network Packages

Are you going to put it back up or not?

hi
i have the same problem --- same dish 1.8 c.master although mine i think is a bit older ( the mount is a bit different )
a lot of the play in mine was the bearing in the jack - but even though thats sorted now, there is still play elsewhere in the mount
which can afect the signal in strong wind
had mine about 6 or 7 years now and the previous owner had it a similar length of time -- i,m very happy with it --

it took me quite a while to fine tune the arc tracking though -its very sensitive to quite small adjustments . i enjoyed setting it up --and learned a great deal --mostly the hard way as it was my first motorised dish l.o.l.

regards .c.c.

I wouldn't say I cant receive it, just some adjustment needed. Yes it will be going back up

Thanks for that chorleycat, my polar mount is home made, so it just goes to show that the original CM mounts have play. I was going to try and get hold of a 2and hand one, but wont bother now.

You are correct tho, it is very sensitive to set up.

My CM 1.2m with matching feedhorn is fitted with no ring exposed, are you saying that if I fit it as CB has ie with one ring exposed would my signals would be improved?

Nice dish. I have the same .

However, the pole was not well fixed. Now, it needs to be readjusted.

Do you have a detailed instruction how to adjust this dish. Google and channelmaster URL didn't help.

Thanks,
