I can not get any Ku on 55 Degrees West, I can pick up a few data transponders on 53 Degrees West Ku.
Also I do not think that 55 Degrees West is a circular satellite, Lyngsat shows the transponders listed as H and V, Lyngsat does show 53 Degrees West to have R and V transponders, so you must be thinking of it.
I just blind scanned 55 Degrees west and I found some new audio channels that I liked, I hope they are permanent channels and stay FTA, they should since the channels are broadcasted on Shortwave Radio.
Since the channels are not listed on Lyngsat I can not name them.
