[aprssig] Re: weather filtering,.........

[Robert Bruninga]

I agree completely.
We must get greater responsibility on the part of IGate
operators to *design* their path to only cover 
*their back yard* local area and not QRM distant
areas who get hammered from all sides.

In my opinion, IGates should never use more than
a single WIDE2-1 (one hop) path, unless there is
a clear reason to do otherwise.  APRS software that
supports IGates should have DIFFERENT PATHS for
the two functions of 
1) the owners local RF path for HIS packets (2 hops)
2) IGate traffic to RF should usually be only 1 hop

We need to get software fixed to do this.  

Would anyone like to collect data for 24 hours on
all IGates and lets see how they stack up as far
as their outgoing path is concerned?

Ken,
    As a APRS user for over eleven years this is a sore subject here. I get 
wx alerts from at least eight stations, sometimes thirteen or fourteen 
stations, usually sending out the same useless stuff. Why would someone 
think I would care about wx 150 or more miles away? There is a station up 
near Peoria that sends this stuff out at least once a minute sometimes.  I 
generally don't care about wx 50 miles away and if I did there are much more 
accurate and reliable methods of getting the information. NOAA radio, 
broadcast radio, TV, Internet, cell phone, and of course the old reliable 
windows that I have on the house and vehicles, come to mind. We also have a 
very active ARES group locally.

    I can't think of a single occasion where I checked the APRS screen and 
said "Oh, my! Someone has sent a WX alert and I must change my plans!"

    How about if all wx alert stations used no path or only WIDE1-1. That 
would get it to those in the local area but not bother everyone else.

    The SUPLIST in your TNC is your best friend for the most prolific wx 
alert stations. Unfortunately, mine only holds up to ten callsigns,

Rant mode off. Flame suit on.

73,
Al, K9SI
