Lat & Longitude is for receivers that have Diseqc 1.3 or USALS....some receivers don't have that option so its not in there
USALS allows you to input lat/long and as lnog as the true south satellite is set up the rest fall into place
For USALS to work, you must properly setup the Dish to Your True South Sat. first(it's a Sat the is on or close to, the same Longitude as you are) Once you are properly aligned to your TS Sat, the receiver can "drive" to the other Sats automatically(as long as the sat list in the receiver is up to date) The receiver uses the Long and Lat that you entered to calculate the other sat locations, based on the Sat List in the receiver.
If you physically set it up just right, scanning the rest of the arc is EASY as pie. We have a list of strong transponders on the section that says "I need a strong transponder to aim my dish" Use that list and you're good to go.
In terms of your motor, give or take, you can go about 60 or so degrees in either direction. Sometimes up to 65 degrees.
Latitude and longitude is extremely important on your receiver. Then, you can just tell your receiver to go to any specific position in the sky.
The issue is clear to me. Since I have two recievers that do not input LAT/LONG the quest here is to find out what the function would be called that I can search for to find in a manual.
I have been reading manuals online, and haven't found any that state something like the following"
"On a motorized system, this reciever will scan the sky left ro right, find the satellites and store their locations."
I deal in a technical world and find it interesting that there seems to be no common termininology for waht I am looking for.
And I believe if its not in the manual, it probably is not a feature in the system. If anyone knows of a rciever that does this, please let me know. I can plug in the locations from here where they shoudl beb foound if necessary.
If they don't allow Lat/Long. that means there is no support for USALS. Time to move to Diseqc 1.2
This involves manually moving the motor....waiting for signal, logging that signal, identifying it, then storing that "position" on the right satellite entry.
Sounds complicated but your basically telling the receiver that the motor is currently aimed at ?? west and this is where you (the motor) should go when I call up the satellite. It's a bit of a throwback but it works.
