Trying to get the arc correct on my new c dish! Have my true south sat 72w peaked and have one other set up at 107.3 west but haven't been able to get anything below 70. I did get 30w a week or so ago but lost it after some adjustments.Can someone find me a good strong c -band TP on something between 50 and 60w?.I dont really want to play around with 30 west right now because thats very near my eastern limit.
