[SADXA] Hamsci paper

[Darrel]

I found this interesting.  Professional science use of the WSPR, RBN 
etc. databases to study Large-Scale Traveling Ionospheric Disturbances.
Published in the American Geophysical Union journal /Geophysical 
Research Letters/.

I presume my own 20m WSPR data will automatically have been included, 
along with many millions of other data points.

Cheers,
