And they seem also to differ from what Ko has captured and sent to me. The only common factor is that at 136kHz there seems to be a sort of clustering of spectral lines, albeit different from location to location. I can only say that the spectrum at my location is time-invariant, sort of. I have always seen those lines, night and day, winter and summer, with no signs of modulation. Go figure... 73 Alberto I2PHD
