The moniker R--- F--- appears often as a Satan figure - The 2 letter acronym RF most commonly means "Radio Frequency" but may be an old Morse code Pro-sign AKA Procedural Sign, the most commonly known (wrongly but conveniently) is "SOS" or ...---... in Morse code (read dit - dit - dit - dah - dah - dah - dit - dit - dit) - there are many others - "RF" in Morse is .-. for R and ..-. for F - run together "RF" could be .-...-. which can be parsed (grouping of contiguous dits and dahs) as ETVE or AVE or LETE or LAE or LR or EBTE or EBN - of course I'm trying to get to EVIL or similar - reusing letters and using imagination or just miss-coding EVIL is possible - or maybe Stephen just got burned by the high powered Radio Frequency electricity in one of his three AM and FM broadcast stations when he touched something near the transmitter that was supposed to be safe to touch - 73's
