sorry to hear about your tumble, and best wishes for a
speedy recovery !
I continue to be fascinated by the QRP potential of
the high alitude balloons, it would be really cool if
findu.com had an option to show not only the position
of a unit, but also it's radio 'view shed'. A simple
view shed of course can be made by drawing a circle of
radius 1.2X x ht^.5, and a more accurate view shed can
be made by using the topo data and the Longley-Rice
propagation model such as what's done by the
super-awesome freeware "Radio Mobile".
Not only would the APRS balloonatics love this
feature, but repeater operators and users would love
it as well, as a very convenient way to visualize
repeater coverage areas. Heck, the SAR folks could
use this for real-time co-ordination of setting up
basecamps when they are starting a rescue operation.
