i'm up to 18 sats ranging from amc3 at 87W to amc7 at 137W with my hts tracker system v and am playing with the pansat 2500a now and am hitting alot of sats with it also....so i guess i have it basically tracking the arc correctly....
as for the actuator arm i have to wait alittle while until i get a few extra bucks to buy one that will reach farther....all i had was the $40 i spent on the new 18 inch one...i'll get a 24 inch one when i can...just glad to have it moving correctly for now....
