Thanks for the info Dave. Im trying to attach  a screen shot but Im having
trouble.Its only a 50k little jpeg.

Here is a link to it.Notice how the signal around 20khz starts together then
slowly splits. It appears at the same time he 18.1 signal appears...strange.

I do not think that was real signal--more like some sort of local QRM.
Tuning circuits required for power at VLF make doing such difficult.
