Dabbling with a spectrogram at 29501 Hz and back-dating it a couple of days turned up this http://abelian.org/vlf/tmp/29501_140302a.gif Apparently a signal, approx 2014-03-03 02:00 to 07:00 UT. The timing corresponds with Bob Raide's Morse transmission on 29499 and I wondered if it was a sideband but there is nothing showing on the LSB at 29497 Hz. http://abelian.org/vlf/tmp/29501_140302b.gif I'm a little bit puzzled by this. It's too strong anyway to be a sideband of Bob's Morse. Maybe I have a software fault. Or was somebody else transmitting that night? -- Paul Nicholson -- |
