kd4e,
To my trained ear that sounds like a power line arc.
Also, given your description of how broad-banded it is.
Also, noise blankers in most rigs work on low rep-rate, narrow
impulse noise (like arcing sources, with 1 or 2 arc-strikes per 60Hz
cycle.)
So, there you go. One man's (informed) opinion.

Good point ...
How about this?
