[RFI] Anyone have a guess as to the source of this noise?

[AA5CT]

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?

AM mode on 14.256
