The OpenTracker and Tracker2/Tracker3 series can all switch profiles
based on altitude. I usually set up my balloons for one hop below
5000 feet (some of the terrain around here is > 6000 feet) and
direct above that. With the MX145 transmitter the Tracker3 can be
set up to transmit on different frequencies at different rates, so
you can use 144.39 for a packet once every minute or two for backup
tracking and a separate channel for much faster updates. We haven't
had a packaged version with the MX145 in a while, though.<br>

<div>I am happy to write an article and put it on my site. I am
fairly knowledgeable about APRS but I admittedly have little
experience with balloons. So... What are the recommended
settings for balloons that maintain "politeness" but don't
degrade functionality for people trying to locate them?<br>
<br>
Are there particular hardware setups that are recommended? I saw
some comments about hardware that can change settings based on
altitude.<br>

<span>I think what is needed instead of lots of words on this

more sites (Copmcast killed web hosting or I'd still have a
presence) that respond to "APRS Balloon tracking" and many
variations someone may try searching for, so that anyone
trying to figure out how to set things up can find it
easily. Or perhaps a periodic article in QST, or some such

<span>I started doing some APRS with a used D700 back in the
late 90's. _ALL_ repeat _ALL_ the stuff on the net back
then assumed the ham was very experienced in packet -- which
is completely unnecessary. It took me years of reading this
sig (and only understanding pieces of what was posted) and
plodding through mounds of outdated Packet information,
packet-turned-APRS information, Packet-sort-of-turned-APRS
information, out-dated APRS information, old PDFs and
PowerPoints ROTTING on the Web to get to the point where I
decided I knew enough that I felt it time to write something
for newbies, so I wrote my own Beginner Guide in terms a
beginner could understand. It was well received by comments
I received.</span><br>
<span></span><br>
<span>And if someone does, do not give a long drawn out
history of Packet., APRS, or your travels through Ham radio.

<span> #yiv9889509495 I think we all agree that HABs</span><br>
<span> should not use abusive paths or beacon</span><br>
<span> rates. However, the reality is that many</span><br>
<span> of these balloon launch teams are populated with</span><br>
<span> inexperienced hams who simply are not aware of how the
APRS</span><br>
<span> network works or how their HABs impact the network.
Those of</span><br>
<span> who do have considerable experience have a
responsibility to</span><br>
<span> educate the balloon teams. Discussion of abusive
balloon</span><br>
<span> launches occasionally pops up in online APRS
communities.</span><br>
<span> But, we have to keep in mind that we are preaching to
the</span><br>
<span> choir. Typically, these balloon teams don’t hang out in</span><br>
<span> APRS groups or reflectors. Jason is quite correct.
While the</span><br>
<span> balloon launch may seriously impact the APRS network
for the</span><br>
<span> time the balloon is in the air, that time is short and
the</span><br>
<span> network will get back to normal after the balloon is
down.</span><br>
<span> Meanwhile, we should take note of the callsign being
used by</span><br>
<span> the launch and attempt to reach the holder of the
callsign</span><br>
<span> to politely educate them about APRS</span><br>
<span> networks. BTW, in my experience, Jason does,</span><br>
<span> in fact, have a clue. Berating him really doesn’t</span><br>
<span> accomplish anything. Bob… From:</span><br>
