I am trying a new setup at a trailer park.
My dish is 33 inches ,KU,C band Lnb.
When i aim the dish at 97 W do i have to add or subtract for the magnetic deviation?
Thanks!!

You add the magnetic deviation to the true azimuth direction. As Jorgek says, use dishpointer.com. it makes it all a lot simpler.

The way I try to remember is when aiming, add the magnetic decl. to ur magnetic compass reading.
When measuring Azimuth subtract the magnetic decl from the magnetic compass reading to get the bearing relative to true north.

I've always just pointed my dishes using either a receiver/tv on the roof with me, or with a spectrum analyzer. The SA is particularly useful for setting the skew to mimimize the cross-polarity interference. I ended up using a old battery powered handheld lct tv, a satellite receiver installed indoors, have the RF output of the receiver fed into the cable using a diplexer, and another diplexer on the roof so I can get my RF video into the portable TV. When I'm done the installing, I take out the diplexers and weatherproof the outdoor connections. I still prefer to aim with the SA, but it's 90 pounds, and I DON'T like hauling it up a ladder more than a couple of rungs to a low roof!

His question was merely about how to read a compass.
I don't put satellite antennas on the roof. As long as you have LOS, put em on the ground on a pole for easy access. I use a computer based tuner to aid fine tuning. Your computer can be accessed remotely from your cell phone.
I have never once dragged receiver equipment outside for tinkering in the yard.
Albeit, if you have done things correctly, a guy shouldn't need to get out there very often for tweaking, if at all.
