Thread: Really don't know what's wrong

Been on here moaning and groaning before. Hope this is something simple.
Experience: novice

equipment: 10' mesh button hook disk, Ventura 24" actuator, Chaparral Corotor
ll Plus, Norsat 8515 C band and Norsat KU 2707a, Uniden pusher.

My f/D is 37+. The calculations for setting the Chaparral calculate to 37+.
I had to put it to about 30 to get Classic Arts Showcase and the goodies
on Intelsat 9. Must be the old button hook dish causing this?

I have just started working with this new stuff and can pick up C-band on
G12 133 degrees W. and Intelsat 9 at 58 degrees W.
Lowest W sat is AMC 10 at 135 degrees.
Lowest E sat is Intelsat 805 at 55.5 degrees.
I tried to tune in AMC 11 and could get nothing. Even C-span analog
on tp7 didn't come in.
If more info needed just ask.
Thanks for any help.

Hello Shankle!I feel your pain on getting a new system to work correctly.In my case i think i finally got it set up good!getting over 25 sats and c/ku working very well from 30 to 133.It takes time and patients!In my case it was a combination of getting the declination angle,true south and the LNB adjusted correctly to get my results.I know its a pain!but it might be a good idea to go back to square one.Make sure your true south is set up correctly!check declination offset angle,and dish elevation angle at true south.Find a strong TP on your true south satellite and the move dish with the motor until strongest Q sig on receiver.I found out that if the LNB is not adjusted correctly it will make a difference of a Q sig of non to strong.It took me several trys to get my ku/c LNB to work well with both bands.I found out that i got my best results when i started with my true south sat then going west or east one sat at a time blind scanning each and checking to see how the sig was then slightly adjusting the declination angle if needed then rechecking the true south again.Its a bit of back and forth action till the arc looks right.Hope this helps! Stan!!

I whole heartily agree.
You must get the sat closest to your true south first, to get anything started in the right direction.
If your only getting the east and west side and nothing in between your polar mount angle and declination are way off.
Elevation and Declination Angles are always measured and applied when the dish is at its zenith, i.e. highest point in the arc, when the dish axis is aligned along the true north-south line.
To get started in the right direction you need your correct Polar mount angle and offset tilt(declination) go to this page
Satellite finder, how to point dish with magnetic north, azimuth and elevation program calculator.

and input your site lat and long. Adjust your mount to the indicated angles, and find your most southern sat.
Before going E or W. adjust feed for highest Q .
Then move east or west, and at find the next sat,then the next if Q starts dropping off in either direction, rotate the polar mount on the pole slightly, find that sat using actuator, compare Q, if less, you rotated wrong direction. repeat, Pretty soon you'll have the whole arc.

Especially the modified polar mount declination angles, at the bottom of that page.

Have you already posted some pictures of this dish and the feed?

Is it possible the button hook sags as the dish turns?
Some guy wires (anything that won't stretch - actual fishing lure steel cable comes to mind) might help.
Perhaps four of 'em, equally spaced.
AND, make sure the feed is centered on the dish, too! -

You made a point of getting the F/D correct, but did you tune the focal length?
When you can't tune the focus and peak the F/D independently, it's hard to optimize.
Best, is if the dish arms (or button hook) actually hold the feedhorn (easiest if you use an LNBF), and then the scalar floats free on the feedhorn.
(Tune the feedhorn for focal length without scalar, then put the scalar on and tune it for best signal quality.)
But, if the scalar mounts to the dish arms or the button hook, and the feedhorn slides into it, you're really handicapped on what you can adjust.

Thanks guys for responding.
I have gone through the declination thing long ago. But I will set the dish at
my high point and do it again.

I haven't uploaded any pictures of this dish yet.

The F/D is not correct. If I set the Chaparral to the recommend setting
nothing comes in anywhere. To my understanding the focal lenght is
controlled by the button hook at 37+ inches.

The feed horn and lnbs weigh about 2 1/2 lbs. They could be affecting the
reception as I roll the dish. I will install the guy wires as Anole suggested.

The chaparral corotor ll plus is not connected to the scalar ring. I had to slide
the feedhorn in way past the recommended value for this dish to pull in anything.

I really hate to mess with the E/W adjustment or the declination as I did get
signal at the extreme W and E. This makes me think I am on the arc.

So this thread will be in limbo until I get the guy wires installed.

The list of my equipment is in the 1st post here.
Longitude - 82.50, Latitude - 29.10
Axis - .62 more than local Latitude
Zenith - 33.94 = Axis - 29.72 + Declination - 4.22
Been through this many times in previous posts.

Guy wires are now installed on the button hook pipe.

If I position the dish at it's zenith the LNB is 7' up in the air and 4' in from the
edge of the dish. NO way I can reach that to fine tune. Right now the Chaparral
is way in past the point it should be. Only way I could get c-band signals at
133W and 58E. The zenith is pointing to AMC 9 83 degrees W. It's KU and the
only thing for FTA there is "Retro Tv Network and Tuff TV" on 11735 H 4444.

So should I run it down to where I can reach the lnb and reset the feedhorn to where the
calculations say it should be and run it up to the Zenith and try again? Then try fine tuning
the Declination and Azimuth till I can pull in the stations on Amc 9(83 degrees W).

Don't get to technical with me as I am a novice.
By the way what is "Q" in the previous responses?
Thanks for all help.

You can run the dish down to where you can reach it, but you have to be really creative to imagine where it's going to be once you move the dish back up to true south. I'd borrow/buy a ladder, and get used to climbing, if possible. Just lean in a little and you can work on the lnb, and with a 10' dish you won't usually be blocking all the signal while you work-so you can watch your tv or meters to see what adjustments are doing for it. Be careful if you're not ladder-experienced.

I too have a 10' button hook and I have the guy wires attached. I fiddled with mine forever to get where I am now which is moderately happy, but I can't leave well enough alone so when it cools a bit I am moving it to another location so I can receive sats further east. To be able to work on the lnb if it is like mine loosen the bottom nut all the way to the bottom of the bolt allowing the dish to swing down and adjust your lnb then when you're done bring it back up to the top nut that you left alone and you should still be in adjustment. I did mine countless times to get to where I am now. Still had to use a ladder but was workable. btw "q" is signal quality.

Thanks guys for helping.
I'm an old geezer and have images of falling into the dish and wiping another
one out. It won't hurt me except my pride.

I have a 10' ladder. How's this idea sound? Get the ladder as close to the
dish as possible. Tie ropes at the top and fasten them to a truck. Then if
I lean over the 4' necessary the ladder and me won't fall into the dish.
Can wrap one leg around the ladder for support.
Hopefully. Or as Mick said lower the dish a few dozen times.

This is also a very slow process for me as I am in Florida and just can't
stand the heat long enough to get anything done.
Let me know what you think please.
