From what you say (which I did not previously know) a LF amateur band has been specifically denied in USA . I would be interested to know what reasons were given.....just tell me if there is a website

We reported quite a bit at lwca.org on the attempt to gain US  2200m privileges.  The ARRL had additionally proposed 160-190kHz in their petition, but in 2002, the FCC turned down the latter request.  It was claimed this 30kHz segment would be too unwieldy from a spectrum management standpoint and might place the power grid in too much jeopardy.

 

Still, all indications in 2002 were that the relatively tiny 2.1kHz slice at 2200m would fly through.  After another year dragged by, the power industry persuaded the Commission that a huge guard band around 137kHz would be necessary because of the extremely lax tolerances in the industry's PLC gear (thus, my reference to our Fourth World power grid) and that it would cost them tens of millions to upgrade their stuff.

 

ARRL may have some of their stories archived.  We have the FCC Report and Order from 2003, with a summary of all their considerations on the matter at that time.  It's at:

 

I hope that helps.
