". There is even a 136kHz ham

kinds of frequencies as Tesla did using the same kinds
of antennas, and then try higher frequencies with
modern antennas and see how much better they work. ;)"

That isn't a ham band and requires a special license application.

Wasn't the poster (i.e. Steve Conner, GM0TET) in England ? The UK has a LF experimenters band. In the U.S. we've asked for it several times and been rebuffed.



 Look
for "Part 5" under FCC rules and regulations.  You don't need a license
to operate between 160 and 190 kHz if you keep your transmitter power to
1 watt maximum.  Not too much you can do with it, but guys are getting
signals across a couple of thousand miles with that power.  Very slow
speed keying.

And, regardless, Type B (damped wave), e.g. Spark gap transmitter, emissions are strictly forbidden.

You might be able to get a waiver or STA for a suitable historical demo, though. Now that GPS has superseded Omega and Loran, there's not so much activity down there (you'd have to show that you wouldn't interfere with LF and MF nav beacons though)
