Vapor, I get a answer from a other forum for the EAST #. (Take the west longitude of the satellite, subtract it from 360, and multiply by 10.) Voila.I played around with the v1.7 but have yet to find an option to do so. If I find one I'll post. The best thing imo is to edit an existing list or upload a fresh one from the stb. There are two files for the viewsat from what I've seen. One being a CHA file and one .sat file. There should be both in the file section. I know there is a .sat file dating back to 2015 so it should be pretty current I would think except for a couple of birds. Again I'm more used to editing for the SV and it only has a single file so I'm a bit lost as to why the VS has two. Or if both are needed to update the sat list. I'm assuming as with the SV you can upload/download a fresh list from the VS via USB or with the editor. Probably the only two that would require editing name wise with the existing .sat file would be the AMC 6 for 72W and ES 4 to for 77W. Of coarse you could probably leave the named as is and just update the tp list. If the VS is like the SV it doesn't go on the name of the sat but the degree motor wise.
If the VS is similar to the SV you could edit the sat name and most things in the tp list in the stb but not the degree of a sat. example 72 to 72.7. Like the VS the SV had an editor some what designed for it or one of it's cousins. So somethings could be edited outside the stb with that editor or CM. If you couldn't edit something with one editor you could with the other. But both editors had there issues. Just have to play around with them and see if using one or both gets the best result.
There is also from what I'm seeing a sat list bulit into v1.7 for the VS that I would assume you could construct a fresh list if one wanted to go that route.
Would have included some screen shots but laptop has issues and I have to go into safe mode to get some stuff to come together to post screen shots lol.
