How to Tune a Dish Antenna

This is easiest accomplished using a satellite locater, available at even Radio Shack, for approximately 30 bucks. This device uses a homing signal and will cause a bar and obnoxious sound on your receiver to inform you of the intensity of your signal that you seek.

It is discriminatory in that it will only select communication satellites. However, there are computer programs that have specific satellites, such as for 2 way communications that are also available. Once you do your explorations, do your mapping. Pay close attention during your initial explorations, pay close attention to the local that you are in if you are travelling, and make a schedule of the signal. You can then make your chart for reference using the map and compass.

I used to set up systems. Mint Condition

If you are using a compass don't forget to take into account the magnet variation. The magnetic poles are a considerable distance from the geographic poles. Geo-stationary satellites are above the equator which is referenced to the geographic poles not the magnetic poles. A good map will have the magnetic variation on it usually in both graphical and numeric terms, it will say something like

Magnetic Variation 7º 32.25' E

Which means a compass will point 7 degrees and 32.25 minutes east of the geographic north pole. On World Aeronautical Charts WACs you will see purple lines in half degree increments that join lines of equal deviation in a similar way to the way isobaric lines represent atmospheric pressure on a weather chart.

Masu,

You are referring to magnetic declination. You are substantially correct, except that declination will vary depending on where on the earth you are located. Here in the USA Midwest at this time the declination at this time is nearly zero, but it changes a little every year. Around 40 years ago the declination here was about 5º. There is a website that has a declination calculator. It requires you to know your lattitude and longitude, unless you are in the USA, then you can put in your postal ZIP code. It also has a link to the Getty Thesauras of Geographic Names to help others. The result for my ZIP code, 63304, is like this:

Declination = 0° 9' W changing by 0° 6' W/year

According to the Thesauras and the Calculator, Sydney, Australia is:

Declination = 12° 37' E changing by 0° 0' E/year

Interestingly, you can go back (or forward) in time and see what the declination was for any day between 1900 and 2010.

So, Masu either lives far from Sydney, or he is looking at old published data from years ago.

We are pretty much talking about the same thing except the deviation has any local variations caused by things like deposits of iron included while the declination is just the difference caused by the location of the poles. The figure I gave was just a number I pulled out of the air and figure you gave for Sydney sounds right to me.

Give this site a try. It helped me. http://www.satsig.net/ssazelm.htm
