I'm only aware of two stations operating on 530 kHz: CIAO in Fort Erie, Ontario, and the RVC station in the Turks & Caicos Islands, yet this morning I was hearing at least three (maybe four) stations! One was a Male talker, one was playing sorta pop music, one was playing EZ listening. At the moment it sounds like someone is airing some Arabic vocals (that could be CIAO).
So, where are the other signals coming from - assuming that there are only two stations on the frequency? Maybe Cuba? Maybe reflected signals from outer space?
America needs a sense of humor...
