Hello!
If you click on the "W5" in the "Program Satellites" and the screen continues to the next step in adding a satellite you can just add W5 with your 4DTV receiver finding the position. If the screen keeps staying the same everytime you click on the W5 then you need a "Master Reset" on your receiver. I just did my master reset and G1 133' was the satellite that I first programmed and the position is 5000. The next satellite west is C4 135' and the number is 5055; next west is W7 137' and the number is 5113. For every 2' steps to the next sat the value has been about 55. The W5 105' shows up at 4307 which is 693 lower than G1 if you can do it manually or to see if you are close. Simple instructions are at NPS website: www.callnps.com . I hope this helps!!!
