It presents as a green band on the waterfall about a hundred khz apart.  Any ideas what this  might be?

Probably a CFL lamp or switching power supply.

Thanks, George.
It was a switching power supply that has been in service for over a year with no problems.
It's history now.

George, clearly, beat me to it. I wouldn't have guessed switched PS but I was going to offer it was very close to you as white is indicative of strength and, how many signals in the waterfall show as white?

I'm getting the same crap all over the bands, the strongest on 40m, it goes up 15m....watch this: https://www.youtube.com/watch?v=u_2jFgUZ4Mk every 60kHz, I suspect industrial type SPS....
