But magnetic south is about 193 in our area due to the difference between true south and magnetic south. I've done some work in david_jr's neck of the woods and 61.5 is about 175 deg magnetic plus or minus and 72 is about 192 deg magnetic plus or minus so in fact where he is in MA the point for a 1000.2 EA dish is probably pretty close to 188.

Here's a good calculator to find the magnetic deviation in your area:

Thanks. That may explain why I had to aim a dish slightly to the southwest to hit the Bell satellite at 82 W, which would be pretty much due south of where I am. :)
