One of my favorite radio shows is from an utterly obscure low power AM radio station in Hamtramck, which puts out an ultra lofi low power over-the-air signal on AM 1610 and a digital broadcast on http://am1610.org . The show is "The Strait", which features Detroit electronic vinyl. It's on Saturday nights from 10:00 p.m. to midnight, and it's always worth a listen.
Some day I'll get to Hamtramck and do an air check and make sure I can actually tune this in – I don't know if they cover the whole city or just a piece of it.
