I know @Wabbit and probably @Oak, @Spoon and even @LotusBud knew of Dr. Bill. Maybe even @Starling heard Dr. Bill once in a while late at night on the AM dial, due the “the skip signal*” ie the am wave travelling much further at night when it has less radiation from the sun up in the sky battling for air space.
They call it the skip signal because on one night the signal might leap over Idaho and Wyoming etc but come in loud and clear in Minneapolis.
