While tuning in the Hifer spectrum I came across a signal like I've never heard. This was recorded at 0100 UTC 1 March 2002: http://www.gostanly.com/w4dex/BC/13495khz.wav The frequency was 13495 KHz. The signal was stronger when I first heard it at about 0030. Can anyone identify this or make a guess as to what it is? Dexter
