[aprssig] NE Illinois Balloon Tracks

I did post them to the balloon group.  Here's three of the replies I got:

 From Joe:
it lasts a few hours,  get a life.

What is the group to do when the tiny 200 milliwatt transmitter is now 
on the ground?  Think many if any digis will hear it to be able to be 
gated to the net?

They need the somewhat long paths to be able to gram ANY station they 
can so they can be heard once it's landed.

This  crap about abusing the network is just as crazy as when someone 
runs a crossband repeater on a somewhat popular frequesncy and someone 
complains because for 2 hours their dead quiet call channel between 
themselves and their buddy 5 miles away isn't quiet and a private call 
channel between them two anymore for 2 hours.


 From Harry (KC5TRB APRS since 1985)
Not a thing wrong with the path on any of the three balloons!

 From Joe responding to Harry is the best one...
I know,

ever since that one guy in I think florida started to make a stink  with 
these redickulus trackings of  listing what digi dit it hit,

Like a 200mw signal is gonna cause any problem anyway,

these jerks need to get a life

Anyway, such is life and it goes on.  I figured by posting here, anyone 
that can actually get one-on-one with the launchers (or other future 
launchers) can use these to provide a visual of the overkill effect.

PS.  Yes, I AM that "guy in florida", and I think they responded as they 
did because the KNOW the graphs point out an abuse on their part.  Oh 
well, it's a big world and life is too short to worry.
