I am pulling numbers in the 20's for many
C Band stuff. A perfect example is 40.5. Picture is very watchable without any breakup. I am getting high 80's to low 90's pretty much across the board with the 90cm on Ku. Has been a bit since I have taken any readings from the C Band side but when I have a chance I will look again.
As to fuzzy might be my eyes
But seriously I have many channels that are far clearer than others. Have not looked to see if FEC was a factor or not but I do believe bandwidth usage is the culprit. A really good example is Zee TV DVB on C Band. Crystal clear to the point of being better than
HD on DTV or DN. Flip side would be RTN on G10R. Of course that could be the quality of the film prior to transmission also. Caught Boy in the Bubble (I think that is the name of it) on White Springs this weekend. Was so fuzzy I did not watch it. I have seen the same with sporting events. Some are crystal clear and others have the old analog broke down edges look to them.
Maybe fuzzy is a bad term. Perhaps blurry would be better.
