On the night of December 19, 2005 UTC the 40m band was very quite here in north Texas. There was propagation but it was long. I was tuning around the low end of the band when I detected a carrier on 7012 kHz at about 0245 UTC. After listening I noticed that it was an AM broadcast. I switched in the attenuator in and out to make sure that it wasn't some sort of IMD response in my receiver. At first the signal was weak but as time progressed the signal improved. I noticed that the sun was rising in east Africa and signals usually peak just after a local sunrise, particularly with signals from the far side of the planet. The clincher was when I heard the identification of Radio Galkacyo at about of the middle of the recording below. A quick search on the Internet revealed that several years ago this station had broadcast on this frequency of 7012 kHz.
It is interesting to hear how signals peak during the gray line path that exists during the sunrise and sunset periods of various parts of the world.
