There are a number of sources that I use to compile into the "big picture" (pun intended...lol)
This page gives a hot linked list of current satellite names sorted by orbital location. C and/or Ku service is represented by the color code. Follow the links for more details. The sat specific info is sometimes "dated" but it is still generally accurate.
North & South America - LyngSat
Another site for info and usually the most up to date listing of available content can be found here.
MPEG
As with all these sites, there is a lot more knowledge to gain by exploring the entire site.
Our "home grown" source of satellite activity can be found on the "The List" tab at the top of the page. It is compiled and maintained by board members, and input from members observing new activity is always welcome.
There is some concern on a potential end of service "kill hit" by the current "powers that be" to the 4D IRDs. Some are recommending removing them from the DCII stream until some point after the 1st of the year.
The concern is that the hit will affect ALL 4D boxes that are in the stream, not just the ones that are/were subbed thru the reseller that is selling out C band. There are several threads on the subject you can review and form you own opinion on the potential danger.
If your FTA rx is in good working order it can be very helpful to get you initial dish alignment. If you have a dual band ( C and Ku) feed on your BUD that would be the ultimate setup. I recommend using a
SATELLITE signal splitter to share the C band signal between the two receivers for now. Mine is set up for the "power pass" port to the 4D and the "power block" to the DVB box.
If you are using an LNBF (13/18v polarity switching) you may want to do your with the "power pass" on the DVB side. That will give you easy access to swapping the polarity for testing purposes via the FTA box and can be very handy for testing. The polarity on the 920 is hard coded to the specific channel/sat combo and cant be controlled on a per transponder basis. (You can invert the H/V configuration for ALL the satellites at the same time via the options menu)
Be sure to use a
SATELLITE signal splitter, not a
CABLE splitter. A cable splitter will present a short circuit to the LNB voltage and eventually, possibly immediately damage your receiver(s). There are several brands and they are pretty cheap. I have Perfect Vision brand. Check the site sponsors for this and other goodies you may want/need.
I've found it easiest to compile a handwritten list of "beacon" points sorted by orbital position containing polarity, SR and polarity info. For birds that dont list free DVB content try the PowerVu TPs. They are DVB too, just encrypted.
Once you have panned the arc and noted the count for each location you can go back and set the specific tile to it's count. Tweaking may be necessary. Keep you pen and pad handy to note specifics about each location you are programming in.
After you've got your locations set up then you can go back and scan in the DVB stuff. Open DCII stuff comes and goes. Once you learn where to look it's just a matter of keeping an eye on it.
Keep in mind
None of this matters until you can get a DC light at G1 ch3 to get the current sat tiles and channel maps (before they go away) Focus on that 1st then find W5 (105°W) and get the X4 channel map there. After that you can rest easy and set this up at your leisure.
To determine which 4D designator goes with which orbital slot you will need a list of that to.
Here are a couple of online lists. I dont know how accurate or up to date they are.

NPS - Your One Call Solution
...Oh. and DONT call NPS. I'm surprized that info is still up. I'll reserve personal comment (invoking the if ya cant say some thing nice cliché) but read around on the board. There are numerous views and opinions on their actions and motivation regarding the future/longevity of consumer C band subscriptions.
Well that ought to keep ya busy for a while...lol
Be sure to read and heed the 4D warning threads......
