These days i'm calibrating the colours and angles in my ELF...VLF
spectrograms. The colour of ZEVS is now calibrated to deviate less than
3 deg. However producing a spectrogram in 1 mHZ FFT bin width, i can see
sidebands of ZEVS.
Did someone else observe a similar effect?In a first thought i would assume it is my timing system that causes the problem. But maybe it is ZEVS itselfe? Or even propagation? 73, Stefan PS: Capture attached.
