It's a skin therapy for what sounds like skin cancer.

If you use Google search engine and type in Blu-u light in exactly
that way, (I copied and pasted from you email ) You will come up
with several hits and I think the model number and MFG is Levulan
model 4170
I have a simular signal here only it sounds like motor noise from a
idleing car and it goes on 24 hrs a day, day after day only on twenty
but spread out across the band with a couple of peaks which are S6.
My antenna picks it up to the NE of me and I suspect a couple of
houses that must have a dimmer or some kind of such device, sure is a
pain.
Good luck with your problem. I've got a feeling this is going to get
worse what with all the junk gadgets and clever devices MFG's are
coming out without any regard to licensed services and a FCC not that
interested in HR.
