I'm fairly certain the Bethel, PA transmitter site is still working. The website says they are still broadcasting and even have a time schedule up: [www.wmlkradio.net]
From Wikipedia:
"The term tetragrammaton (from Greek τετραγράμματον, meaning "four letters")[1][2] refers to the Hebrew theonym (Hebrew: יהוה‎) transliterated to the Latin letters YHWH. It may be derived from the verb that means "to be",[1] in the existential sense of the verb 'be' (that is, 'to exist'), not in the copula (as 'to be someone'). It is considered in Judaism to be the proper name of the God of Israel used in the Hebrew Bible."
Although the Jews claim that there are 72 names of the creator, but this might confuse someone trying to give a sermon in an effort to raise cash for the latest church addition, 250kw transmitter or to send missionaries to Florida to save the savages. Orlando is rife with them.
