[Orion] Orion time domain issues, QSK

[Martin Ewing]

Because of the lately revived discussion of Orion's QSK, I decided it 
was time to finally publish a manuscript that has been lying around on 
for some time.  Check out blog.aa6e.net <http://blog.aa6e.net>.

I got interested in time delay while trying to make sense of ionospheric 
backscatter echoes.  The Orion makes a fair radar set, but you have to 
understand how it is delaying the Rx signal.  This sheds some light on 
the QSK problem, too.

Comments welcome.
