Perhaps. 

At this point, since no one else heard it, I suspect it is "local", but, BOY!, is the signal ever 
weird!!! I've never heard anything even remotely like it. 

At times, it sounds, literally, like a steam-engine's chuffing at a low level across the entire 
band, while at other times, it sounds almost like a keyed, horribly unstable, CW transmitter 
at S-8 to S-9, followed by some periodically-recurring very wideband, drifty data 
transmission.

Then it as suddenly disappears at it appears.

It is going to be difficult for me to track down.

Furthermore, it is "new", as I spend a lot of time on 40 meters and have never experienced it 
before.

So far, due to its relatively short duration, I have not been able to discover it on any other 
band than 40 meters.

Keeping my fingers crossed...
