Laurence there is a BIG difference be= tween radio=20 amateur transmitted signals and Commercial operators
Regarding LF plots, suffice it to say= that if you=20 read my message you will see that I can copy OE5ODL on=A0 9 Khz in a=A0=20 qrs 3 window.

What is the point sending a 1 - 24 Kh= z plot also I=20 use narrow band reception not wideband.
