I'm puzzled that that list shows an entry for 43W (although at least it's marked as unverified) because I've never seen any reference to that satellite having a Ku beam to North America.
The only other full-time channels I've ever seen are on 45W and 15W if you can get down to that. I'm not in front of my receiver, so I'm going by what LyngSat has listed and hoping it's current. I can check later tonight maybe.
45W has one channel, from northern Africa, 11608 H 1852. LyngSat has two other channels listed, but one disappeared a while ago for me and I've never seen the other one. I'll have to check again.
On 15W, 11964 H 14714 has channels from Equatorial Guinea and Angola. (Soccer fans may find games there.) 12170 H 45000 is a pay-TV transponder that often has a few channels in the clear. Some receivers will act flaky with the high symbol rate though, so best to try with the first TP I mentioned, then look for this one and let it sit for a minute if it doesn't show up right away. There are actually a bunch of these S2-45000 transponders, but it's rare to find anything else in the clear. There are also one or two weak transponders with religious channels.
And that's it, as far as I know. If you can get a motorized dish to go down that low, then 37.5W, 22W, 20W, and 12.5W all have occasional feeds. None of them have full-time transponders for us, except maybe 37.5W. It used to have data transponders, but I haven't seen them lately. I could be slightly out of alignment though, and it's not a strong satellite for our area. 8W used to have one transponder with educational channels from Brazil, but I haven't seen it lately, and they were encrypted the last time I did.
