Airwaves: rf signal. No cable.
Channels 38, 42.. others at times. This in SF bay area, that is. Think 65, 64 get in on it too, but I only look sporadically. Dunno what else might be on cable, as some equal-time for weirdness kinda rule?
I see them typ. after 1 AM. Sometimes the guide shows a succession of such, pretty well filling 1-5 AM. There may be many more around country who come on 6ish, as you say.
{sigh}
What I haven't ever seen - is anything reminiscent of a normal 'sermon'. These guys 'explain' in such minute detail exactly [didactically] "what She Means" - you know they didn't read this in the normal locales. It's in their *minds*

Your sig has an eerie verisimilitude to the way these guys say.. "you oughtta live" ;-)
