I hear a signal that sounds like a buzz / large fan motor running , what is it ? I thought a jammer like the buzz over Radio Marti but I never hear a normal broadcast signal under it ,with Radio Marti jamming I can hear Radio Marti under the sound.
This sound shows up everywhere in the band from 2.0 - 30 Mhz.,day or night. Naturally following where the best propagation is. It fades up and down like any SW signal. I heard this same signal when I was a kid in the 1950's on SW.
One place it seems to be most nights is 6845 Mhz , it looks like it occupies 5khz.
What is it ?
