I have a clone pansat reciever and when i perform a sat scan i get almost all channels for 110 and 119 but i get doubles of all the channels, for example 100 for echo7 and for echo8.6. I have good level strength and excellent quality strength i can watch almost all the channels for echostar 7 and 8.6 but sometimes i have to switch back and forth with the channels to get them to show. Is there something i did wrong on set up or could i have a hardware problem? Thank you in advance for any replies.
