Keeps you're getting some where now, an would like to add 1 more thing on top of what Rainman said, on the declination, you're 1st picture is right, but when you check declination I like putting the angle finder on the large satellite ring (where the panels bolt to) upside down an it should have 4 degrees added to you're elevation that you got in you're 1st picture. Now on you're 1st picture if you would just turn you angle finder upside down an move it out on the edge of the ring, then you should have 32 degrees on the angle finder. or if you got enough room put the angle finder on the center plate (upside down) that bolts in the middle of the dish.
Elevation 28 degrees
Declination 4 degrees
28+4=32
An good to here that you been getting some pictures, but at 1st I would not get crazy peaking in for the arc just yet. I would try to find Galaxy-10 Just up from 3ABN on G-5, (that you found) an peak the dish in for that sat 1st, reason why you can reach the feed from a step ladder, an their is C & KU vertical an Horizonal their,(go tru you're transponders an pick on a week 1) an try to mainly work with the ku on the peaking in. then take some time to FINE tune the the bsc-621 in for polarity, then in an out (focal depth) realy take little extra time on the feed. make sure that the feed is centered in the dish can check with a tape measure. by doing this 1st it will make you're job easyer on doing the peaking on the arc. an also if you're feed isn't peak in well it may give you side lopes an trow you off a bit, on seeing the center of the true arc.

Good going Keeps you're on the home stretch now.

had no luck on any ku signal. just want to make sure i have this correct.

first screen is my KU settings

second screen is my C settings

how do these look?

*also, the di electric plate in the throat of my LNBF fits into the slot provided right?
i picked up a weak signal and made minor adjustments to the lnbf but to no avail.
the square box on the lnbf should be facing straight down or at 4 o'clock when actuator is at highest point or half way extended?

friggin mosquitoes are killing me out there!!

remove dielectric plate.
You don't need it right now.

You might not need it at all. Its for specialized circular sats, of which you are not looking for at this time.

Hopefully the link will work, it shows the alighnmnet indicator.
THis guy has it at 2:00 for some reason, mine pointed down to the ground (at 6:00)
http://www.satelliteguys.us/attachme...1&d=1143472638

also shows good starting point for position of lnbf in scalar ring (how much sticks out)

123 is not your south sat. You show having the positioner set. If a stationary dish I would not be commenting on this but you have to get yourself setup on your south sat first or nothing will fall into place unless you get extremely lucky.

keebs · #35 (**permalink**) 05-19-2008, 06:13 PM

gotcha on the south sat. just had no luck on it so i just started moving it and bam! found something, it gave me hope.

elgemcdlf · #36 (**permalink**) 05-20-2008, 08:34 AM

What did you find?

keebs · #37 (**permalink**) 05-22-2008, 09:04 PM

i took out that di electric plate and almost immediately started getting KU. now i need to figure out the relationship between my fortec and the vbox. any tips would be much appreciated.

keebs · #38 (**permalink**) 06-21-2008, 11:34 AM

still having some trouble with focal depth i guess? true south sat is clear and a few around it either way are good but when i go to 97 and higher i get nothing. my lnbf is in its harness kind of cocked on an angle. but it gets great signals on the sats i have found. anyone have their lnbf like this too? when its flush its not so great. oh man this is driving me nuts!

pmb1010 · #39 (**permalink**) 06-21-2008, 12:06 PM

if you are on an angle like that it's focusing on to the side of the center of the dish.
Sort of like a multiple LNBF Directv dish does.

So - I suspect if you need to do that your alignment is just a bit off.
You need to move the dish TOWARDS where the lnbf is pointing then put it back centered and move the dish up a little to compensate.

If your center is good and your ends are bad tells me you're out of alignment too.

Fun ain't it...

Keebs if you have the lnb-f cocked a bit, then 1 of the legs that are bolted to the scaler ring may be bent at 1 end or the other need to use a ruler an do alot of measuring to get it in the center of the dish. you can even use a lazer pointer taped inside the feed throat to help you get it centered. now was looking tru some of my satellite paper work the other day an found a Perfect 10 spec sheet, an will give you the info for a 7.5-foot perfect 10 dish, that may help you out.
F/D ratio> .375
Gain@4GHZ> 38.7
Gain@12GHZ> 47.2
Percent Efficient> 60 percent
Focal Lenght> 33.75"
These where all taken from a Perfect Spec Sheet, an I didn't know that they made a 14.5-footer also.

Now I know that the BSC-621 does not have any of the F/D ratio stamped on the side of them like a Chapperal has, but what i do here is take a old feed that has the markings on it, an lay the 621 right next to it an mark it with a sharpie pen, then my F/D is right on.

Now have a G-box here running a 10-footer with a Pansat-9000, but don't know if the working of a Fotec is close to that of a Pansat or not, never owen a Fortec. but if it is let me know an will help you out with the motor control end.

Hope all Helps Keebs, need to get her up an running.

I CAN GET THIS AT A GOOD PRICE. WILL THESE HOLES MESS WITH IT?
CAN I REPLACE THE SCALAR RING?

keebs · #42 (**permalink**) 08-24-2008, 09:42 PM

anyone???????

keebs · #43 (**permalink**) 08-25-2008, 07:20 PM

HEY! ARE THESE HOLES DRILLED INTO THIS THING GONNA COMPROMISE MY SIGNAL? WHATCHA THINK?

satnutwillb · #44 (**permalink**) 08-25-2008, 07:31 PM

You should be alright.Looks like someone might have used that with other lnbfs attached.

keebs · #45 (**permalink**) 08-25-2008, 08:34 PM

Yes That Is Exactly What Was Done. Thank You.

those holes in the scalar should not effect a thing keebs as long as they aren't in the dish you should be fine.

Okay so I had no luck with my BSC621 so I ditched it and bought the Chaparral with the co rotor and a 4dtv receiver to control it. I had a ton of trouble trying to find focal depth and skew with the BSC621. I couldn't get both of them in together. I got both C and ku in my attempts but never was able to get all to gel. I am hoping that the co rotor will aid in my quest? What do you guys think? You all have helped me in the past and Just wanted to know what you thought? any tips on starting an install with 4dtv receiver and co rotor? I felt real defeated with the BSC621 and really need to get this running. i got a good price on this stuff.
