[aprssig] [OZAPRS] IGATES in south east qld Australia

Hi Andrew,

I wouldn't assume that just because you've opened the Internet->RF path that you will be sending *all* of the Internet to RF.  My bi-directional iGate only sends a packet maybe every few minutes, when it's busy, much less when it's not.  

It all depends on what is coming in from RF, which after all, is kind of the point.  APRS is a *lot* more useful when the iGates are bi-directional, and a network that requires 2-3 hops in order to get to the Internet is not likely to function well enough to be useful, and therefore not get used for anything except 1-way tracking.

  DON'T set your station up as an IGATE (i.e. DO NOT 
  gate data from the Internet to RF). This will only create traffic loops and 
  problems on the channel.    
If there is no IGate 
  serving your local area (i.e within 2-3 digipeater hops), or there is no 
  APRS activity at all where you are, please contact your local region 
  co-ordinator so we can integrate your area into the network effectively.

  What you dont want
   
  01. DIGIS beaconing every 5 minutes
  02. INET to RF traffic swamping the 
  freq
  03. No INET to RF path (messaging)
  04. Mobiles not being able to get 
  through
  05. Mobiles sending at high rates
  06. Unnecessary geograhically non relavant data 
  being sent to RF from INET
   
  What you do want
   
  07. Digis beaconing sensibly
  08. INET to RF kept to a minimum or even just 
  messaging
  09. Both ways messaging
  10. Mobiles have a good chance of getting 
  through
  11. Mobiles sending at sensible rates and using 
  smart digi where possible.
  12. Geographically relavent data sent to RF IF 
  you have to.
   
  At the moment, we have some of 01, 02, some 03, 
  some of 04, some of 06
  
  At the moment, we have some of 07, none of 08, 
  some of 09, some of 10, some of 11, some of 12
   
  Remember, not everyone has rx capable 
  mobiles
   
  And if the packets are to help people at home, 
  they should really be using the internet to help with bandwidth.
   
  Conserve the RF spectrum

    I recently fitted the car with 
    APRS.
     
    I am hearing some INET to RF traffic on 145.175 
    MHz
     
    I am hearing almost constant INET to RF traffic 
    on 439.100 MHz
     
    What I find weird is, most people seem to be 
    running dumb trackers, ie they can't even RX the packets.
     
    My question is, who or what is the INET to RF 
    supposed to support then ?
     
    I am not sure everyone is doing both way gating 
    as well, I tried a few INET to RF messages.
     
    Surely you would favour the 
    mobiles.
     
    It makes it really hard to impossible for 
    mobiles to get out.
     
    Can you please look at this 
    situation.
