OK - I tried it - and not surprisingly, it shows I am down in a hole - with
the average decifficent being -14 meters.  The only way out is to raise the
antennas substantially, or use a much higher angle of radiation...now my
question -  can I tilt my antenna upwards to partially compensate for the
local terrain?

Thanks

Scott

Seems to work well with inputted GPS data.  The results all seem
reasonable.  I guess I won't be doing much LOS DXing!

73 and thanks for the info.

calculate HAAT (Height Above Average Terrain):
http://www.arrl.org/news/features/2006/01/06/1/?nc=1    For those of you not
familiar with the concept, when applying for various FCC-issued licenses, an
applicant is required to determine the height of his proposed antenna's
radiation center above the average elevation of the terrain around the
proposed transmitter location, averaged over a distance from 3 kM to 16 kM
away, along eight or more radials.

for the full 360-degree azimuth.  However, that figure is actually negative
from approx. 330 to 350 degrees.  So much for eastern Asia and PacRim
stations.
