Disclaimer: I am a 59 year old FTA novice. Messed around with this stuff years ago and am now giving it another try. This will be a trickle of info. Just received my Manhattan RC-1978 yesterday. Looked quickly over the manual, unplugged my old receiver, and hooked up the new one. Pretty straight forward. Programmed in a couple of birds. Picture looks good. Then I figure out I am about 2 degrees off. G3C channels show up on G19. G19 channels show up on G16. Looks like I need to make some alignment changes.
