Ok,
You said you intend to get an FTA rx (rx=receiver) in the future, but do not have one now. Unless you intend to do that before you do this primary alignment, lets set all that aside for the moment to minimize confusion. BTW, FTA receivers are for receiving DVB (a mode of digital tv/radio modulation) signals.
Since the dish came from withing a few miles of where you intend to use it, the inclination/declination alignment
was likely close enough to use without alteration, presuming it was not tampered with prior to you getting it. If you can get back to those points, or close to it that will shortcut a big portion of the setup. The primary factor in those two adjustments is lattitude of operation, so unless the dish was more than +/- 15-20 miles north or south of it's new location the original adjustments are probably close enough the get rough alignment.
Analog signals are pretty sparce, and ones that are continously present even harder to come by. ARTS is one, on tp5/G1/133W, and Dr. Gene Scott and his daughter pastor on analog, somewhere over on the easten end of the arc, I dont recall ATM. Iceberg or some of the other guys could pop in and give you that sat/tp info.
I looked at Lyngsat's............ uh, did anyone tell you about Lyngsat?....

anyway, I looked at their listing for AMC6 and they dont show anything that is continous for analog. There isnt anything there for the 922 to see either ( but several FTA channels in DVB.
)
Piggybacking would not change anything, because the 922 is a analog + Digicipher 2 (DCII) unit. Depending on the last time is was in service, may only have the analog side enabled (no channel maps) If it will allow direct remote cotrol input to access channels above 24 then it may be usable to find some non analog signals.
There are some variables that are polarity related that will need to be looked at. Since you have changed the LNB assy you can see that the rotational orientation in the scalar ring can affect the points that the polarotor move the element to. If it is mpt in the right place in the ring the element wont be driven to the proper place. No worries, that is not a difficult fix.
Essentially, you want the element at appx
45 deg of travel (appx center of its adjustable limits) when the receiver has an output that is centered in it's range adjustment for a given polarity. This helps keep you from the edge of the physical limit of the servo to get the best polarity setting for the channel you want to see.
Another variable is the configuration in the unit you are using to control the polarotor. On the 922 Option 6-4-2 shows a page that, amongst other things, lets you rotate the polarotor output signal by 90 deg in software. It doesnt really matter which you end up using, as long as it is in agreement with the physical orientation and limits of the unit outside.
Your conversation with Skyview....did you sub to a package for your 922 thru them? If so that can be an advantage if we can get pointed to the right spot to get the authorization downloaded to the rx. If you have a sub, it would also help to know what exactly you have been authorized to view and where it is.
See if you can get the adjustments back to where you think they originally were, and find a means to be certain that you can determine true south, compensated for magnetic deviation for your area.
Regarding FTA and subscription, all NA providers require that you use an IRD of their design, and do not support aftermarket units. You can sub the 922 (if the info to do so in memory is still intact) to most if not all you listed, and more, and for a better price than you would pay to the pizza pan, LSD (little silly dish) providers.
FTA has a lot of free stuff that you can view without anyone complaining. There are even 'cable type' channels open (unencrypted) from time to time for anyone to watch if they can catch them open. A good source of sports and news uplinks as well. I highly recommend supplementing your setup with an FTA DVB receiver. They are relativity inexpensive anymore, (Ebay'd ~60-75 bucks or less shipped)and for the most part created equal for a given set of features, until you get into the several hundred dollar price range. If you come across one you figure is in your pricerange, and want some input on it, post about it. Chances are somebody on the board has one, or know something about it and can advise you on it.
Get the dish back to it's original settings if possible, if you have a sub, get that info together too, and we will take a look at what you have to work with.
