Well, I think I have an ID but I also think I'm wrong.

I had weather in english by a female computerized voice on 6518.80USB. Heard on 04/10/16 at 910PM AKDT (0510UTC 04/11/16) in Galena, Alaska using a Tecsun PL880 and 80 foot longwire.

Here's the audio, all 7 minutes and 3 seconds worth:

Click here to listen on YouTube.

It was fairly clear and pretty steady here in the middle of central Alaska.
It was giving weather for the Caribbean and apparently the only hit I can find online for either both from Eibi and Google says that 6518.80 USB belongs to Punta Carretas, Uruguay.

If that's really what I heard, A.) It was strong and B.) Why was it in english?
I suspect I didn't really have them and it was from somewhere else. This signal is just to be good to be Uruguay, but a DX says they are the only things that come up in a search for 6518.80 USB but the times I heard them don't match.

If you can help Paul, please comment!
