Re: Tesla Coil RF Transmitter (long)

By the way, in the US anything under 9kHz is not regulated by the FCC. I am wondering why not build coils in that range?

Sorry :-/ I am in the UK. I didn't realise you never
had in the US. Europe has had it since 1998 I think.
There is a restriction of a few watts, but it's ERP.

Ralph Hartwell runs WC2XSR/13 with a 400 watt
transmitter on 168kHz. I think he is still within the
power limit due to the antenna being so inefficient.

I suppose I should have mentioned that, but I thought
it went without saying. Quartz locked SSTCs only ;)
