[Elecraft] VLF/LF Converters

[Jack Smith]

Geoff:

There are a dozen or so experimental stations in the 500 KHz  range 
operated by a group of hams. http://www.500kc.com/ has more detail. It 
seems that not too many are actually radiating as of this time however.

There are also quite a few "lowfer" Part 15 (unlicensed, but permitted) 
beacons in the 186 KHz range.  The Longwave Club of America is a  good 
starting point for these Part 15 operations. http://www.lwca.org/

No 136 KHz amateur operations here in the US, unfortunately.
