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.

Jack,
Although I do not have any details to hand there is some Amateur CW
activity in Europe within a few kHz of 500 kHz, and I believe that
crossband to HF contacts are made also.

Those interested in listening to signals below 500 KHz with their K2
or K3 may find my new review of Jackson Harbor Press's inexpensive
VLF/LF up converter of interest. It's at

I've been using it with my K2 and an active antenna I'm working on
and can hear WWVB quite well here in Northern Virginia, along with a
number of other stations.
