Not knowing where to put this, I'm putting it here. Feel free to move this post if it's in the wrong place.
Pulled in an interesting signal today. While cruising around downtown Fairfield CT, I decided to do a brief frequency test of 1690 AM, an intended Part 15 frequency. As I was passing the Fairfield Public Library (at about 2235 UTC/5:35 PM eastern), I heard a bit of music on 1690....specifically, Dan Hill's "Sometimes When We Touch". A quick scan of both Radio-Locator and FCC records revealed no licensed station on that frequency, at least not within 100 kilometers.
So....this leaves me wondering what, and who, this station could possibly be. Any ideas?
