As far as I remember, that band was never a ham band. It was occupied by
some carrier-current devices (which ran over power lines). It's actually
part of the long-wave broadcast band. I think that a lot of experiments
were carried out by hams and others using equipment that complied with Part
15. Because antennas are so inefficient at those frequencies, you could put
a lot of RF into an antenna and still not radiate much. Official
internationally-agreed allocations are around 137 and 475 KHz, although I
don't remember which of those are fully legal in the USA at the moment.

Is that still a ham band and has anyone ever heard any beacons on it =
before? I read an article about a guy in Canada and a guy in England =
that actually made a contact using software the sent and received dits =
at 30 seconds and dashes at 90 seconds, or something like that, and =
actually established a contact many years ago.
