Thread: this motor is driving me nuts!
10-20-2012 11:30 AM #19Professional Hobbyist
Would be nice if these positioner assemblies were a bit beefier design and use a 1-2 amp motor with an external (12v?) power supply. They would move way faster and handle heavier dish assemblies, maybe up to 6'. Of course you can make your own polar mount and use a linear actuator for smaller dishes too... was thinking along those lines for my 1.2m dish myself...AzBox Ultra, 10' bud, C2 LNBF,WSI-9036, SG2100 with SNH-031
MicroHD, 36" no name dish (and sharing C2 above), SG9120B, SP1PLL
+ various dishes, LNBs and receivers

You old-timers/experienced guys will get a laugh out of me wasting a day but ...
What would be nice is if
The manual for the HH90 had had in the directions for setting up *dish* elevation when setting up USALs which they omitted, but included in the section for setting up DiSEqC1.2
The motor was easy, I found my Latitude, made sure post was level/plumb, made sure motor bracket and motor were level ...nothing to it.
BUT dish elevation bracket ...
In USALS section (and many online videos and explanations) it says (after motor Latitude step)(referring to on back of dish, not the motor, obviously latitude doesn't change)
"Align the dish elevation and tighten fixing screws.
(no explanation how to get what the dish elevation angle needs to be)
ok, so I went to Dishpointer, my Longitude is 98, I think "true South/True South Satellite is highest in the arc ...so I find Satellites at 97W and 99W, my elevation for both of those is 54.1 so I set elevation on back of dish to 54.1 WRONG
DiSEqC1.2 section of same instruction book ... same step (after motor Latitude step)
"How to find the elevation value of the dish"
"With the same latitude angle, calculate the elevation angle of the dish according to the formula (the "45 number" in the formula below varies by motor model/brand and has to do with the bend angle in the motor's arm)
Dish elevation to highest point of arc sat if it was a stationary dish
54.1 in my case
(45 minus your latitude) (my lat is 30.76)
so my dish elevation should have been 39.86 instead of 54.1
Seemed like I should have just been able to take an inclineometer to 54 degrees on the face of the dish, and that formula needed checking hard to believe they'd leave it out in the first instructions
SO I went back to Dishpointer, and saw ....
"All Satellites | Motorized Systems | Multi-LNB Setups:"
and I thought ... hmmm cool
so I had my address in there already and had dragged to the spot in my yard where the dish is and
dropped down and picked the motor I have HH90
Dish Setup Data
Motor Latitude: 30.8°
Declination Angle: 5.1°
Dish Elevation: 40°
Azimuth (true): 180.0°
Azimuth (magn.): 175.3°
So 40 is close to x=39.86 (dish elevation I took 20 hours finding out how to calculate
and 30.8 for my latitude on the motor is already set
11:00 pm I go lower the dish elevation from 54 to 40 and do a usals scan and there's a bunch of stuff on satellites
I need to correct the left-right azimuth a bit due to my brand new compass dial from the satellite finder kit melted in the heat.
If they had had the formula they had in the DiSEqC1.2 section back in the USALS section ... (or better instructions to go to dishpointer, look for motorized instead of looking up your true south satellite, and select which motor you have) I'd have saved a day... and a melted compass
I would have never found the formula under DiSEqC1.2 for elevation, since I was using USALs I didn't feel I needed to read the DiSEqC1.2 directioss .... except for this sentence in this post
HH Motor Install, Frustration and Recommendations?
We abandoned USALS and I programmed 8 or so satellites using DiSEqC1.2.
so I installed using USALS and the formula they didn't tell me in the USALS directions ...

now the funny part, after finally locating and installing a motor
I just got a UPS notification that the DG380B I ordered, and forgot to cancel ... was just shipped
Guess I'll install an FTA system for my brother or something now that I know more

Or you could sell it to me, as I ordered a DG380B from Sadoun months ago and he never shipped it so I canceled the order.
I need a DG380B.
You can have UPS re-route a package before a package is delivered to you, and have them send it to a different address. I think it is free to do as well:

Think about it... I'll send you the PayPal over the weekend before the package gets to you so you can re-route it...
