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.<br>
<br>
All of the plots are available at:<br>

<br>
The high resolution *-RF-7.png images show the balloon's actual path
inside the red blob and lets you see more of the completely
redundant green digipeater links at the fringe. The larger red dots
are IGates and the smaller red dots are digipeaters.<br>
<br>
The following link is a dump of the raw packets received by all
APRSISCE/32 IGates that mention KF6RFX. This includes the BALLOON
ANSRVR group launch detection and various DX reports from
APRSISCE/32 IGates. The packets received per IGate can be found in
the Packets directory of the original link.<br>

<br>
At its peak altitude (apparently 104,038 feet), I counted 41 copies
of the packet received by APRSISCE/32 IGates across a span of 10
seconds (remember, digipeated copies take time to propagate,
especially on a busy frequency).<br>

PS. Note that these plots were generated from raw RF traffic as
received directly from APRSISCE/32 IGates. You won't see this sort
of coverage information from the APRS-IS as it will show only the
first copy of any packet received. The RF traffic represents ALL
original and digipeated packets received by any APRSISCE/32 IGate
with no duplicate suppression.<br>
<br>
For comparison, here's the much less dense APRS-IS dupe-suppressed
pictures of the two balloons. mostly IGates as the directly received
packets are typically delivered to the APRS-IS much quicker than the
digipeated copies which end up dupe-suppressed out of existence.<br>

this morning to hear the WIDE1-1 digipeater in my APRS
igate/webserver setup keying up every 10-15 seconds constantly.

There are TWO balloons running a WIDE1-1,WIDE2-1 path every 10
seconds at 30,000', about 20 miles west of Detroit.
<br>
<br>
o They are hitting:
<br>
<br>
o CHLSEA (VERY wide area digi about 10 mi west of Ann Arbor, MI)
on the first hop, and my digi on the second.
<br>
<br>
o And my station directly, with the local Lansing area wide as
the second hop.
<br>
<br>
o And the local Lansing-area wide on the first hop.
<br>
<br>
o And at least two other digis directly and/or via second hops,
within 40 miles that I can hear off the air from here.
<br>
<br>
The result is almost 100% occupancy of 144.39 non-stop, as
monitored off-the-air, in the Lansing/East Lansing area. (And I
assume most of the rest of Michigan, northern Ohio, northern
Indiana and southwest Ontario.)
<br>
<br>
A clear demonstration, if there ever was one, of why one should
NEVER NEVER NEVER use WIDE1-1 in the path of an airborne trackcer
<br>
<br>
This log is monitored off the air with my TH-D7 listening to my
digipeater/igate in Haslett, MI (about 5 mi north-east of East
Lansing, MI)
