Well, here's something you don't hear every day. My Airport Express, which I've had since shortly after they were released, is now picking up AM radio. The output is very quiet, but very clear; with amplified speakers it's distinct. For some reason, if I connect just the left audio channel, it becomes quite loud. Were it wideband noise or some such, I'd chalk it up to EMI -- but this thing is quite accurately tuning in a local station (1580khz). Has anyone else seen this?
