So many questions but watch this & how many of us stare at the same 8MHz SDR slices he is!!!
I would have liked to inquire how they handle below 30MHz but this is a rare view in any case...
The joke of it is [having worked in radio most of my life] Percon has to update the FCC ULS database because it is too "complex" for the FCC to do, as the license originator? Percon has done this for the last 20 or so years! Great gig if you can get it
