if I was at 74 I should be able to just drive the dish easy further to get a lock on 72 right.
Yes. Since you don't have a Sat located at your Long, you just have to take your time tweaking.
What I would do is.......
Drive the Dish to it's highest point - look at the back of the mount, see that everything lines up
Take a couple pieces of Masking Tape, place 1 horizontally on the pole, and the other directly above it on the Mount - make a Reference Mark on Pole and Mount with Pen (so you can return if the following does not work)
In the Receiver, setup AMC 6 Ku, and select / enter the NBC TP:
12053 V 6890
If no Quality reading, loosen the Mount Bolts just enough to make Azimuth Adjustment - do not drive the Dish
- 2 degrees is about 1/16th inch, so slowly, very slowly twist the Dish to the East and West, watching for a Lock on the NBC TP
- When you get a lock, make a new reference Mark, on Pole and Mount (you may need to drop the Elevation 1 degree)
Next, in the Receiver, set up AMC 9 Ku, and select the RTN TP:
11735 H 4440
- When you get a lock, make a new reference Mark, this time just on the Mount
- Adjust the Mount Azimuth to split the Difference between the the AMC6 and AMC9 marks - that should get you close to the proper Azimuth
Again, do this with out driving the Dish.
Tighten up the Mount bolts, and triple check that Mount is Plumb, and Elevation is correct.
You should then be able to Drive the Dish and hit those 2 Sats.
When tweaking, keep it simple....
Start with C Band - Pick 2 Sats that are about the Same distance East and West of your Location (Longitude) say Amazonas 1 @ 61west and Galaxy 17 at 91west - be sure to use known Hot Transponders
Only Adjust the Azimuth and Elevation until Sats on either side need the Same Adjustment, then adjust the Declination
Keep in mind that with every adjustment, the GBox Position number will change slightly
Tweaking your first Dish will take 10 times longer than you think.
