I've been reading this thread for a while, but haven't jumped in til now. I don't actually have any HD at home yet, I'm just staying informed so I'll know what's going on when I do. Anyway, I'm an editor at KVTN, and we are on the air. I'm not an engineer, so I don't know exactly what our power is, but on the monitor in Master Control, it has been pixilating a lot, and this morning there was no audio. I don't know if that's any help, but I have been enjoying reading this thread, so I hope that I can contribute more in the future. Keep up the good work.
