The RTN channels are cool. NASA & Pentagon Channel are a must. I also like
Mhz Worldview for the occasional Rugby match.
The DC Path wild feed was cool. Snow falling on the capital was cool on a projection screen! 24/7 as well as the cam over President Ford's casket was different.
I dont have FTA right now even though i would really like to have it. All that i really need is a reciever and this would be great. From looking over all the channels available i would say that Gospel Music Television would probably be my favorite though because of several of the Southern Gospel programming it lists.
My favorite FTA channel is TraceTV on telstar 12, it has great music videos, no commercials, no brain dead veejays, no dumb reality shows!!
I like retrojams also but I find that the audio and video quality is just not there unfortunately... video looks washed out, overcompressed, and sound level varies from barely audible to ok..
