Red lines are the first or direct hop. Green lines are
digipeated
copies of the packets. Rest assured that there are LOTS of
green lines completely covered by the red lines. And yes, the
red
direct links are really that long for a transmitter at
altitude.
The direct RF footprint is big anywhere over 1,000 feet AGL.
That's
why no path i necessary when flying at altitude.</blockquote>

You had a very impressive graphic a while back that showed the
red lines
and the green lines quite distinctly. In my opinion
that was an awesome educational graphic to show balloonists why
a path
isn't needed at altitude. <br>
<br>
As you point out the green lines just aren't visible on the
graphics in
your email and the few PNG files I downloaded.<br>

It all depends on how many direct receptions there are and how dense
they are. In this case, with the 10 second beacon rate, there's way
too many direct lines for the greens to show up. If the beacon rate
had been a more sedate 60 seconds, the red wouldn't be so dense and
the green might have been there.<br>
