Thank you for your comments.
I have heard people who think 1908 Tunguska event was not a natural
event, but the evidence shows that it was probably the result of
bolide atmospheric explosion. This is what I believe. My interest
here is the apparent influence of the Earth's magnetic field
interaction with the meteor's plasma-corona which may have caused
course change. There was supportive evidence by eyewitnesses
description of the event. After reviewing the recorded seismic data
and the barographic data I was wondering if such an event were to
happen today would radios be able to detect any RF emission caused by
the event. In my limited knowledgebase, I could see several possible
sources of broad band energy emission. I know people are using
forward scatter techniques for meteor detection, but that is radio
reflection off the ionization, and is even used as another form of
natural 'skip' for high frequency.
What I was thinking was atmosphere electrostatic discharge or
soil piezo-compression type thing.

My understanding of Tunguska is that it was a "natural" event. I
would therefore assume that any RF noise it put out would not register
as an artificial or structured signal.
It might only be useful to another Civ's planet hunters as proof of a
body in orbit around a distant star. ("Gee Sznorf, if a massive
meteor fell into a sun, you wouldn't expect to see _this_...")
