    Here are the results from my 7 satellite screens.

    1. How would I have such great numbers on most but terrible numbers on a few?

    2. How would I have great numbers AND terrible numbers on a single satellite?

    3. What is the difference between a 0 and N/A on a satellite?

    4. Why is it that I can lose my HD local channels but still get the same channel if I tune it to the SD version of it?

    Thanks in advance for any help!

    "s" satellites are spot beams. Meaning that a part of that satellite is not directly beamed at your market but some other marker either adjacent to you or far away from you. If is close to you, you get low numbers if is far from you, you get 0. But those beams carry nothing you can watch so no need to worry. The NA means just that not available. Meaning not being used. According to those readings, your dish is well aligned.

    And the HD SD issue is "Rain Fade"
    HD is almost exclusively on KA band satellites and much more prone to signal loss in bad weather Rain" etc
    SD channels are on KU band sats and somewhat more resistant to rain.

    A heavy Southeastern style thunderstorm will kill both but SD slightly shorter duration than HD

    And without getting too technical, the following may be convenient to commit to memory when reading your signal level screens.

    99(ca) = Ka A Band CONUS or Nationwide transponders from 99 W.L.

    99(cb) = Ka B Band CONUS or Nationwide transponders from 99 W.L.

    99(s) #1-8 = Ka A Band local spotbeam transponders from 99 W.L.

    99(s) #15-24 = Ka B Band local spotbeam transponders from 99 W.L.

    101 #1-3, 5-11, 13-17, 19-25, 27, 29-32 = Ku Band CONUS or Nationwide transponders from 101 W.L.

    101 #4, 12, 18, 20, 26, 28 = Ku Band local spotbeam transponders from 101 W.L.

    103(ca) #9-24 = Ka A Band CONUS or Nationwide transponders from 103 W.L.

    103(cb) #1-14 = Ka B Band CONUS or Nationwide transponders from 103 W.L.

    103(s) #1-4 = Ka A Band local spotbeam transponders from 103 W.L.

    103(s) #15-24 = Ka B Band local spotbeam transponders from 103 W.L.

    Note:

    Ka A (or "Ka-hi") Band downlink = 19.7-20.2 GHz
    Ka B (or "Ka-lo") Band downlink = 18.3-18.8 GHz
    Ku (or "DBS") Band downlink = 12.2-12.7 GHz
