satmex 6 c-band
Ok I have the answer : Yes, I can pick up that channel at my location. I have a 10' mesh dish, never had that satellite before, so I went searching for it! I found 116.8 first, Got some channel on it really good at 4052 mhz V . Moved the dish east until I had some signal/quality again and there TVT was! Movie with english soundtrack and spanish subtitles. Got a good signal/lock on it here, 32N 86.4W so I would think you could pick it up in TX. You might even get it with a 6' dish, hard to say. This 10' is the only motorized c-band dish I have right now, so I can't test out a 7.5' on it for you. Hope this helps.
edit to add : Scanned in the Vertical side and got 12 channels, UTEG (old movie) AGS TV , a basketball game in spanish (Panteras? Panthers I guess), +TElesur, Mexicanal which says scrambled, 5-6others which just scanned in as No Name,and TVT. Lotsa tv on this bird.
