US SW broadcasters other than WBCQ? Really? 
Forgive me my blasphemy

WBCQ is certainly the best.
Through the late 90's there was interesting stuff on WWCR. I admit I purposely looked for spooky things, like "Hour of the Time" and "Overcomer Ministry". WWCR lately has just been a bunch of frantic save-me-Jesus orgies so I haven't listened in a while, but in the past there were more scholarly religious discussions dealing with history and doctrine etc.
I was interested when WTWW started up about 18 months ago or so, but it seemed to be monopolised by that bigoted fool Pastor Peters so I am not so interested. Still, it is worth mentioning that their 9480 signal comes in very clear from the hilltop at my location whenever there is a line of darkness, using only the telescoping antenna.
Before it gets too cold, I might camp out on the hilltop some night and do a proper survey of the kind of signals I can get from North America.
