Schedule S table shows spots on 12 TPs, but there are diminishing returns. TP 1-5 have 12-14 beams each, but some of the others have only 6 or 7. I suspect, also, that some spot TPs are redundant backups that may never be used. Guide shows numerous channels going off air at 3 am ET, so it looks this thing is happening. Most show “Off Air” for an hour, but for AAD channels it’s only a half hour. Transponder lessees get priority it seems, which is, I think, how it should be.
