Found near 5720 khz USB. I can't seem to find a header - it just seems to start and stop at will. Sounds like a polytone, but unlike the XPA I have recorded before. More similar to the XPA2 recordings I have heard, although still something different.
Any guesses?
For those who are confused as to what a numbers station is, see http://en.wikipedia.org/wiki/Numbers_station
Hello LCDUT, that's neither XPA, nor XPA2. It's really a different kind of polytone.
