Yes, a superdish is overkill for 61.5, but it certainly will work and (due to it's size) reduce your outages due to rain. My dish 500 for 61.5 is already good enough that I'm almost never without programming from that satellite. It takes a downpour of almost Biblical proportions to kill the signal, and even then it only disappears for about 5 minutes.
Dish is actually following a standard, called DVB-S, for their satellite transmissions. Part of this standard is a channel map, confusingly called an "uplink report" around here, which tells the receiver where to look for every channel. This channel map is transmitted on every transponder Dish has in their system, so that no matter what you're tuned to, the receiver will always have the latest info.
If Fargo is already in the channel map, then we know where it's likely to go when it goes "live", i.e. which satellite/transponder it will be on when it's actually available. But sometimes dish moves channels around and where they're uplinked now doesn't mean much. Or sometimes they're uplinked but never become available! Usually an uplinked channel means it's imminent, or coming "soon".
Hmmm. I don't see Fargo listed for tomorrow, nor do I see it listed
here. Don't know when it will be available.
