Thanks for interesting information below. I can see th= e wideband data noise on the SpectrumLab often. It is the reason, why I ha= ve to use a new favourite freq for transmitting, 502,300kHz (insteed 501,8= 88kHz). If the conditions are good, then the noise is very good visible.= But it is not audible here. I can see it at night only.
