I had mentioned in another thread that I'm hearing very little English on the mw dial from here in Costa Rica. I've ID'ed WFFG 1300 Key West, 1640 from Biloxi, and 1700 in S Texas. I was surprised to find that my unid on 1030 is WBZ. Caught a positive ID at 0100 UTC tonight. Fair to good signal mostly in the clear over presumed Mexico City and general mush. Pretty amazing to me that this is my only northern US catch. It's a pretty crowded band down here overall.
