I have had an Atemio Nemesis linux based receiver for a few years. Last year my dish mover got stuck at 97 deg, then I had knee surgery, then winter was here for over 5 months. I just got around to fixing the positioner, however ummnn.. I forgot how to change sats on my Nemesis. The 4 page manual is useless. I am running a Egami image on it. Can anyone help this forgetful 65 year old. thanks.
