[NLRS] Rain Scatter on 10G tonight...

[jcplatt1@mmm.com]

One other interesting observation on the rain scatter.   When listening to
W9FZ's CW beacon, the overall audio pitch of his aurora like signal would
rise by several hundred hertz when I tipped my dish up by around 5 degrees
....... I could "tune" his overall signal pitch by raising or lowering my
dish several degrees.   I assume that this was caused by variation in the
direction and/or speed of the rain scatter media with height; ie, different
Doppler.

>From the ARRLs website on VHF dx records at
http://www.arrl.org/qst/worldabove/dxrecords.html , here are the current US
10 GHz rain scatter records.  The distances are in kilometers so in miles
they are 458, 379, and 319 miles respectively.

Rain scatter 738 WB9SNR (EN62ac) -- W2DRZ (FN02la) 16-Aug-1997
