Anyone correct me if I'm wrong, but I believe Anik F3/Echostar 7/DirecTV 7S are all the same satellite. Each name refers to a different set of transponders (TPs) on that satellite. The link I gave shows everything on 119W, regardless if it's from Anik F3, Echostar 7, or DirecTV 7S. I am assuming this from the observation that I don't see how 3 satellites could occupy the same location simultaneously.
oh yes there is....well actually its 2 satellites at 119 and one at 118.7
AnikF3 is at 118.7. Its circular polarity but KU Band (11.7-12.2)
Echo 7 is the satellite for Dish. Its circular polarity and Dish only has 21 TP's on it (1-21)
DirecTV 7 is D*'s satellite that uses form 22-32
As long as the transponders dont overlap you can have multiple satellites at a location
examples
-61.5 has Echo 3 & Rainbow 1 (now E12)....when Voom was at 61.5 both Voom & Dish had their own specific TP's to use...now both sats are Dish's
-72W has AMC6 & Echo 6. Throw in Directv's sat at 72.5 too. Dish uses the odd transponders, DirecTV the evens
-91W has G17, Nimiq 1 & Nimiq 2 or 3 (I forget)...the TP's on Nimiq's are split
-101 has AMC4 & DirecTV...different bands (KU & DBS)
-110 has Dish Network & DIrecTV there. Dish uses 29 TP's (1-27,29,31) and D* has 28, 30, 32
-129 has G27 & Ciel II...different bands
-148 had Echo 1 & 2 before E2 blew up. E1 had odds and E2 had evens
