What about us poor SWL's

Range is pretty limited - a lot of the 4HV folks are hams - surprising really when you consider the breadth of spectrum and the power associated with SRSG Tesla coils.

I have a nice class E plasma speaker that I built a couple of years ago - radiates nicely at 4MHz as well as producing lots of ozone

Fairly damaging to the cat, though, which is why its no longer in the sitting room
