91, 99, 121 (KBS)
I've never actually checked 99 for feeds. I always seem to just get the Jewish news channel and some Russian radio.
I am using my 8 1/2 foot Birdview for 99W KU band news feeds. I also have a 1.2 meter Geosat Pro dish that is sitting idle. I will give it a try this week and see if it can get the same stations as the Birdview.
Besides the Jewish channel and the Russian radio, I usually get anywhere from 1 to 8 active feeds. When they are inactive, some feeds just show a static image of the White House, Capital, or Times Square.
Part of the interest of feed hunting for me is when I see one and try to figure out where it is and what is going on. For example, right now I am seeing an aerial view of multiple Fire Trucks, ambulances, a yellow taped off area and a bunch of people standing around (no audio on this one).
As for 91 and 121, I am unable to get news feeds off of those.
