*_Sporadic E Radio Waves Explained by Meteors_*

*Cranberry, PA. November 13, 2008.* -- Amateur Radio Astronomer and Radio

Station operator Robert Culbertson, WA3YGQ  has been conducting
research in the skies, on the air, and in the scientific literature in
support of his proposed theories regarding the propagation of radio
waves at low medium and high radio frequencies by the ionized trails of
meteors from space passing through and burning up in our atmosphere.

For more than 20 years, Culbertson has investigated Meteor
Scatter propagation on the air through his use of very low radio
antennas with high angles of radiation.   According to Culbertson,
an antenna radiating "Straight Up" is what we need to study meteors.
He says that the Sun Spot Low is the best time to study meteor
scatter because sun-induced propagation modes are less influential
on over all radio wave propagation during those times.

Culbertson uses maps of the ionosphere called ionograms,  meteor
shower data, asteroid and space vehicle re-entry data, radio contact
logbooks, contest data, volunteer reports, and nightly on-the-air
experiments to test his theories and to predict propagation and signal
fading patterns as they may be influenced by meteor ionization.

With the help of other researchers who gather ionospheric, meteor, and
radio data Culbertson proposes that at least one major type, or perhaps
even ALL types, of Sporadic E radio wave propagation may very well
be Meteor Scatter Propagation.

Culbertson points out further that all of this research this is taking
place at Medium (MF) & High (HF) frequencies and that Meteor Scatter
communication is probable even in the Low Frequency (LF) and
Very Low Frequency (VLF) portions of the electromagnetic spectrum.

Other forms of propagation are most likely enhanced by the presence of
ionized meteor trails.  Meteor influence in the ionosphere and
atmosphere are probably responsible for a larger portion of all radio
signal propagation than we have believed before now.  Culbertson says
that any and all reports from other radio operators or astronomers on
meteors or unusual propagation are most helpful and welcome.
