I've been trying with no success to find signal off Hispasat at 30W. I have a 90cm powered by a SG9120. The arc seems to be tracked well, as I get strong signal from 125W to 61.5W (even though nothing to watch on this one). USALS on my CS8000 HD tells me 30W is out of range? I never set any limits on the motor. Any ideas on how to fix this?
 
If there are no limits set maybe your receiver does not calculate that large of an arc from zero? You could use DiSEqC 1.2 to move the dish to where you want.
 
Just for the sake of completeness, Amazonas 2 at 61 degrees should have one unencrypted transponder -- unless by "nothing to watch" he just meant he doesn't want to see the launch demo loop, Coptic TV, or Polmusic.

Never scanned 61W, I was referring to 61.5W.

DiSEqC 1.2? The CS8000 gives me the choice between "USALS" and "Motor"...
 
What's the elevation of Hispasat for you? I don't have any of the same hardware as you do, but USALS on my system won't let me go all the way down to the horizon. I can't get down to less than maybe around 15 degrees.
 
I'm trying to determine how far I can go on mine. Found Amazonas2 at 61W, so far.
 
most HH USALS motors , or at least the famous STAB 90 has a mechanical limit of 70 degrees from 0. The electrical limit is user selectable by software and from fcatory it is 65 degres I think . Your problem living at 93W is that you are acctually out of the 65 degrees limit for Hispasat 30W in USALS. In other words when the receiver performs the USALS calculation for your longitud and 30W it results in an angle over 65 degrees therefore the motor will not move. If the angle is over 65 but less 70 degrees you can still use DIseqC to manually move the motor. If it is over 70 then yo uare out of luck and more likely the bird is either below horizon or so close to it for you to get it anyways. I leave at 79W and have the same problem for 15W , I have to use DiseqC to move it there but beyond that it it reaches the mechanichal limit.

BTW the CS 8000 I think it gives you the calculated USALS angle so you will see what I am talking about.
 
Yes, I *think* I can get there manually. But since I can't find any signals, it's hard to tell. Some strange things have been happening in that respect. For example, I found the Guatemala Channel on 53W, with a very strong Q, but I cannot find 58W at all (using The List as reference). I found 61W, too. You would think I should find several channels at the 58W location...
 
Other than Hispasat, I've never found anything east of Amazonas, but I may have trees in the way, plus a lot of those satellites probably DON'T cover this far North.
 
Yes, but 58W still baffles me... it's obviously not LOL issue, since I get 53W without a problem. "The List" shows several active transponders and frequencies... Unless in this particular instance, Lyngsat is ahead of "The List", as it does not show anything but feeds and encrypted channels on 58W...
 
30W is out of USALS range for me even at 90.1W. I use DiSEqC 1.2 to get the motor there, and the key to finding it is pretty much bumping the motor East until your active transponder lights up. There's really nothing else over there, so you'll know when you hit it. I've been considering setting up a dedicated fixed dish on 30W to avoid the motor mess.
 
Makes sense, Tron. I may dedicate an old Superdish Elliptical I have laying around to that purpose, too. It should do the job, since it worked fine when I had it parked at the late AMC4 101W before I went motorized.
 
USALS Calculation Limit

Through my own testing and experimentation, using two very different receivers, I found that when applying USALS I could not drive the motor to any satellite further than 59.8 - 60.0 degrees east or west from my longitude coordinate entry.

This may vary slightly depending upon the entry for the latitude coordinate, but if I enter my longitude coordinate as 96.4°W, then I can only use USALS to go to satellites with an orbital location less than 156.4/156.2 °W or greater than 36.6/36.4 °W.

I determined that the same limitation existed when using the Coolsat 5000 and with the AZBox Premium/ Premium Plus receivers.

This limitation was NOT altered by the motor that I used. I tested this with two variations of the SG2100 and with the DG280 and the DG380 motors.

Beyond this point in my arc, I must apply DiSEqC 1.2 motor control to position the motor and align with the sat - up to the mechanical limits of the motor.

I doublechecked my results and the limit I found was actually +/- 59.5° using my specific latitude. Quoted my previous post and highlighted changes in RED

I read in the little booklet that came with mine that the range is 75 degrees to each side of the zero - but I understand now that this refers to the physical range, and these are the limits of the mechanism. It makes sense that USALS range is slightly more limited.

Yes, and then to take advandage of that further range of motor travel, you have to utilize DiSEqC 1.2 motor control.

This is why, for me personally, I have to use DiSEqC 1.2 to be able to drive the dish to Hispasat @ 30.0°W. I use USALS for all my other satellite positions.
