Here are the three stations I identified. Dates and times in UTC:
- WMFE-FM, 90.7, Orlando FL, 2009-07-06, 22:47-22:53, 100 kW, NPR.
- WKGC-FM, 90.7, Panama City FL, 2009-07-06, 22:53-22:55, 100 kW.
- WVAS, 90.7, Montgomery AL, 2009-07-06, 22:55-23:15, 80 kW, Jazz & ID on hour with location.
E-skip is one of those phenomena that makes radio propagation so fascinating. Normally FM signals are purely local or regional, but under certain conditions, conditions that occur sporadically and unpredictably, they can travel thousands of miles and sound almost local when they arrive. That sort of thing is fascinating.
