Or, when you don't use the 4 receivers simultaneously, use a splitter with 4 diodes (power pass one way), and all 4 receivers can be "master" at their own time (also over the motor). Or, use three 2/1 priority switches (cascaded), and create a master - 2nd - 3rd - slave order for which receiver...

I don't know which "this case" you mean? A setup like receivers - splitter - motor - diseqcswitch - LNBs would be possible, I guess. But you seem to mean something different? Apart from that, you can always create a "parallel" motor path, parallel to a diseqc switch + LNBs path. I have that for...

I am trying to understand what you mean: Do you mean that the "ground" of the LNB port of one receiver has another voltage (relative to the 110V power supply?) than the "ground" of the LNB port of another receiver? Or do you mean something else? And what symptoms do you then see happening...

There is one picture at the given link that shows 1 input, 4 TVs. So that is allright. The arrow on the splitter to output 1 is indeed confusing. If there is a diode inside, the arrow indicates the wrong way. However it also might be with this splitter, that the port has 'power through both...

Meaning "crosstalk", as with 3 LNBs to one receiver? But what kind of leakage would there be, from where to where, with 3 receivers to one LNB? I'm not sure. Regarding your temporary solution: you explicitly want a 'master' receiver, that is always ON, for the other receivers to function? There...

Did you already choose the length of the declination bolt, matching the needed declination offset angle for your location? (see my earlier post.)

Good! Though I would personally like to have the declination bolt not at an angle at the L-bracket, as it is now. But it is nice to get such a dish back to life again! Greetz, A33

The STAB HH100 has a solid state relay; maybe the HH90 also? Then no stuck relay contact. I've no idea about the cause of the problem, too, though. STABs do seem to have strange problems now and then, which I don't read about SG2100 (Moteck) motors (which have mechanical relays). Greetz, A33

Let's distinguish between a few things, first: 1. USALS, though it is an abbreviation for "Universal Satellites Automatic Location System", is basically just a combination of an angle calculation (inside a receiver) and the diseqc GotoX command. So to call it a "system", might be derived from...

For a prime focus dish, that is clear. How do you use this sun method with an offset dish, moved by an actuator?

The beauty of the "USALS method" is that you use the exact distance of a (random) reference satellite to the zenith/apex satellite position, so that when you found that satellite, the due south aiming is also correct. And you are not dependent on the sun shining, or not. With a USALS motor...

In the plane perpendicular to the rotation axis (see picture here: USALS for BUDs: ) : 1. distance T-A (I use a positive value for having the actuator at the east side of the axis, a negative value when at the west side); 2. distance A-BB; 3. distance T-BB(zero), when the dish is setup exactly...

I can help with the calculations of 2b and 2c; if needed, I'll give the needed input specifications. In the meantime, you can use the method with the sun at 180 degrees azimuth, as primestar suggested. It's just that the sun has to shine, at the specific moment, and be visible at your dish...

To add to what Primestar wrote, I would use what I call the USALS-method for a (random) reference satellite, which is partly as you describe: 1. Set motor-axis-at-zero and dish (and LNB arm) exactly in line with each other, with proper axis elevation angle and dish declination offset angle, in...

Good plan! :cool: Remember that the declination offset angle for 36.35North (Johnson city) would be between 5.2 (modified motor angles) and 5.8 (traditional angles) degrees; dish leaning forward. For the dimensions of your 'bottom solution'. Greetz, A33

You can see example L-bracket declination constructions in these posts: 1. fixed to the dish ring: https://www.satelliteguys.us/xen/threads/can-a-fixed-prime-focus-dish-be-converted-to-a-movable-dish.393508/#post-4614680 2.with a "pivot" to the dish ring...

Yes, the bent plate should normally not be bent. :-( The bottom L bracket would be part of the declination adjustment, and is connected to the bottom of the pivot/axis; but the part that connects the (adjustable) declination offset bolt to the dish I cannot easily see on your pictures. The fact...

It's easiest when you post pictures of your dish elevation bracket + scale, for us to assess what you have got. Dish elevation scale angle in a motorized setup would for you be about: bend.angle.of.the.sg2100 - 6 degrees. I believe the sg2100 has various tube-possibilities, with different bend...

So, you can select the file/pic, but then it does not load, to be "inserted". Strange; what mechanism could cause that? (And only while replying..)

At what stage does your problem arise? Do you have the button "attach files"? Does anything happen when you click that button? Please describe in more detail, what happens (next). Otherwise noone can help you.... :( Greetz, A33

If it has GotoX function, as indicated in your post, then it responds to the USALS commands. No problem there. Greetz, A33

You do have a STAB motor? The STAB might be peculiar, as to what GotoX command it will respond. See USALS/ GotoX; Raw diseqc commands You have tried with StorePosNn and GotoPosNn commands, when I understand you correctly? I have had a symptom like this with my STAB, with a long, not-too-good...

By the way: It looks like the LNB has a rain protection cap, that you can pull down, to avoid rain getting into the F-connector/cable. Is that indeed the case? Greetz, A33

The question that jumps to my mind: What is his source for these listings? Here in Europe I check the lyngsat, kingofsat, and/or flysat website. Maybe there are more? Having multiple sources adds to the 'completeness', I think. Greetz, A33
