Hello All:
Got myself a 33" Digiwave dish (S750WB), HH990 (SPM990) Digiwave motor and Digiwave 7000 receiver and was doing the setup on the weekend. After getting the setup mounted, I spent a few hours trying to tune my closest due south satellite but was not able to pick up AMC-5 with a linear LNBF (DGL990D - I've been assured that it is a linear lnb and some research on the net seems to agree).
I've read the instructions a number of times now and it all makes sense with the tracking arc, declination, magnetic deviation, ... but I'm not picking up any channels. I must be missing/mis-interpreting something?
Ok, first of all I have checked the mount and it is plumb (in all directions). I then set up the motor for lattitude/elevation (44 degree) on the motor mount. Then I have setup the dish elevation as 30 degrees minus my declination in the manual of 6.7 degrees = 23.3. Then I've aligned the dish arm with center of motor mount arm. I've then set the motor 0 degree reference point to take into account magnetic deviation for Toronto (10.5), so I am setting true south as 190.5 degree on compass. I've tweaked to the east a step or two (and I've tweaked to the west...) but I can't get anything channels scanned on AMC-5. I've left the LNB skew at 0 as the motor show keep it aligned with arc.
For my location lattitude is 44 & Longitude 79, look angles should be 179.4 & elevation 39 degrees, so AMC-5 should be right there. Since I'm using a motor, I've disregarded the 39 elevation setting and set according to instructions for motor (and in the end It should be 39 degrees from the horizontal plane - if I'm understanding this stuff). I've also tried searching for other sats so something that I'm taking as true must be off (I've checked and re-checked mount and settings) or equipment not functioning.
At this point, I suspect either LNBF or Dish itself and was wondering how I can measure the location of the lnb (offset) to verify the arm and lnb holder is in the correct position. Is there any test for lnb checking (other than trying another)?
If someone sees where I've made an error in calculation or understanding, I would much appreciate you pointing it out.
Thanks,
Jaime
