I need to know what is my true south from Miami Florida and

[steak]

which bird I should point to use USALS.

Latitude 25.77N
Longitud 80.1W
Miami Florida
Zipcode 33196

STAB HH100

Thank you ops:

Your truesouth sat is the one located at 80W. You can use AMC5 at 79W as your truesouth. There is 1 deg difference. Use USALS to move the dish to AMC5 before tuning. Make sure you use active transponder and key in you long/lat correctly.

how come my Azimuth is 180 on the Stab motor calculator... isn't 180 my true south?
I am confused :roll:

[dtsexpert]

180 is the azimuth of your true south, that' correct. But you need to find a sat close to your truesouth to aim your dish at, which is AMC5 in this case.
The azimuth of AMC5 = 180 +/- the magnetic deviation.
You can find the manegtic deviation for your location at:

excuse my ignorance, but if my azimuth is 180 degrees and the sat that I am looking for is at 79W degrees, wouldn't I have to move my dish 101 degrees to be able to see it?

Right now I have my LNB pointing at 180 degrees .. is this the right way?
How far am I off from 180 degrees to be able to find AMC5?

Thank you much APRECIATED! :P

No. The "79W" is the orbital location of the satellite.
Where you point your dish to see the satellite changes by where you are in the country. For instance, lets say the sattelite is directly over Kansas (it's not, but for illustrative purposes it is...)

Someone in Kansas, their "true south" is still 180 degrees (that never changes) but to point to the satellite they point straight up.

Someone in California, their "true south" is 180 degrees. But to get to the satellite, they need to point EAST to see it.

Someone in North Carolina needs to point due WEST to see the satellite.

Start to make sense? The satellite is in a fixed position, it never moves.
Therefore, you must use the zip code calculator to convert the orbital position (ie 79W) to YOUR pointing co-ordinates, which for example might turn out to 185 degrees on the compass setting. 185 is very close to "true south", so that would be the best satellite to line up to.

Remember that the satellite "arc" looks like a rainbow in the sky. You want to line up on the highest point of that arc, so that when the motor moves left and right, it follows the arc accurately. If you lined up on one to the left, the sucess of getting the other side to be accurate is diminished substantially.

Hope this helps...

Uhh hehe hey guys... I found the problem y'all are having trying to help him..... here's his first post in this thread:

He mistyped his longitude as 80.1 in the first post when he should have typed 180. Just checked the Longitude finder.. he IS indeed at 80 and NOT 180.

hehe I was editing my post as you were posting steak ehhe. I htought it was a wierd Longitude LOL

Wow yes, thank you so much!!, I was close at least I was pointing to 180 to start so I need move 5+ degrees east or west until I get a singnal

Thank you pmb1010!!!!

nope the latitude and longitud is correct...

I don't think the 180 longitud exist anyway hehe :wink:

Actually it is the variation and "not" the deviation. By definition variation is the difference between true meridians and magnetic meridians which vary by geographic location on the earth. On the other hand deviation is what affects only a magnetic compass by metal, electrical current, nylon clothing creating static electricity as well a numerous other effects..... etc.
Only a very expensive gyro compass will not have nor demonstrate deviation.

Bill,
Do you want to know different name how we call magnetic declination, here it is:
