Ah, but the problem is that the "success" of any one station on APRS is
always at the expense of everyone else. Without the concept of bandwidth
conservation as the foremost principal, only the most abusive signals
achieve the highest success.
This is classic game theory. APRS works best for the most ABUSIVE users.
That is why we always have to counter this NATURAL human tendency with
preaching, warnings and recommendations... ad nausium.... The classic
Golden Rule....
I know it sounds preachy, but the only way to achieve the best overall
success rate for everyone, is to somehow get "everyone" to accept -less- so
that the congregate of everyone else gets "more"... And the funny thing is
that the original user is actually one of these "everyone else" to everyone
else, so in the long run, he gets *more* too.
No question about it. Using an abusive path will work better. But if
everyone does it, then each individual gets nothing...
Classic game theory proves over and over again, that human nature will
always chose to go-for-the-max for one's self, even it means that the
result is no-one wins anything, instead of accepting something less than
the jackpot, that no one will get if everyone tries for it.
So we preach.... And of course it means that if you really need to get out
during a particular packet or a particular position, or a particular
message, then go ahead and step on everyone else until you are successful.
Nothing wrong with that. Just don't do it often, and certainly don't do it
all-the-time!
Reserve the right to do it when you need it, by everyone else not doing it
all the rest of the time... and remeber you are part of "everyone else"...
So again, I am not preaching to individuals, my preaching is to "everyone
else"... of which we are all a part...

Same here,
Actual content showing APRS work as the event unfolded would have been
better for me. The 30-40 percent you did show wasn't long enough. I am
too old for the kid music, too. Soundtracks of actual communications only
would have worked for me.
Thanks,

Subject: Re: [aprssig] Episode 5 - APRSTV online
When this was taped, no one was contemplating putting it on APRSTV, so
there is not much footage of APRS and radio communications. Does anyone
know what APRS client the girl that pops up and says, "Cyclist 32 has
passed the halfway marker" is from?
In future episodes I have planned a review of some GPS units, installation
instructions for using PM7 and NWSGet with UI-View32, building an antenna
specifically for APRS, and in a few months, an episode from Croatia and
Serbia.
If there is a topic you want to have featured, please let me know so I can
work on it.
