Well done, and congrats to everyone involved in the 8.97 kHz test !The spectral spreading in Stefan's signal looks similar in Todmorden and Nuremberg, maybe the TX has been turned on and off with a few times with incoherent phase ? 73, Wolf ( who came home too late to get the local grabber running..) Paul Nicholson schrieb: Here is an interesting peak on the spectrum, http://abelian.org/vlf/tmp/ss100315a.png Frequency is 8970.0098 Hz +/- 2.5mHz. Bearing of this signal was 117/297 deg. Frankfurt is on 114. I've added a spectrogram to http://abelian.org/vlf/nb.shtml There's a very faint line building up as Stefan continues his transmission. Looks like the transmission is modulated now so the signal has spread a little. -- Paul Nicholson -- |
