which file are you asking about. I loaded the 282t file, but it is an old one from Dec 2005. You can look that up in the system info. The 277t still has the most channels. I haven't been able to access dsstester in a couple days now. The 282t file I tested was posted on 6/24. If there is anything more recent I haven't seen it yet. I might be best to wait for an official release from BL at his site future-fta.info.
FTA tester, someone claimed that there was new bin released at dsstester, but its old bin that does not work. It was just prank.Like you say, I would wait until official release from the site you get your bins from and wait for comfirmation that it works before loading anything in your receiver,before you waiste your time.
I tested both the 278t files posted at dsstester. The one in Pansat files is dated 10/2/2005 and the one in Fortec files is the old 273t but has been modified to not work at all. I can't get any system info on it. Don't waste you time on these. The 277t is still the best.
