Configuration Best Practices


The results begin to show some of the abuses that I've seen locally in Portland.

One problem users should recognize is that if your mobile uses a three minute stationary beacon rate and have smart beaconing set to be too frequent, your overall packet count can go sky high on the drive to and from work, or to the store.

So even though your basic rate would not be abusive of the shared resource, adding the corner pegging or smart beacons using the same path pushes your packet count onto the top of the hog list.

Even if you use a no hop path and a one per minute packet rate to make a pretty track on your home screen, you still are occupying a time slot on the air which could be used by someone else. Be certain you must beacon when you do.

Low power, low rates, share the resource!

ps: You do have your home station set to fill in, don't you?


It's very cool to follow flights but please be gentle on the network.

  • No more than one packet per minute. Ok - maybe one every 30 seconds if you have smart beaconing running and want to catch the turns.
  • Don't use a WIDE1-1 path. That will key up dozens of home fill-in stations. It doesn't show on the web since only the first packet is preserved but it's still happening. Your location is so good you could probably get away with no path. Here's an example of 4 packets taken from the raw page on showing packets that were directly IGated - no path needed at all.

  • A terrestrial station needs carried detect on to prevent interfering with local stations. An aeronautical station needs carrier detect turned off. You will be hearing so many packets that if you wait for a quiet time - you'll never transmit.
  • Vans Airforce APRS Forum - not always network friendly but seems to be the premier site for Aeronautical APRS.
  • Here's a note on development of a home grown tracker for aeronautical use. Turning off all paths when in flight should work well: I will also do my part to be a good APRS user and plan on adding a new feature to use No Path once I'm flying over a certain speed. I can't use Altitude because the GPS only sends your current Altitude and you never know the Altitude of the terrain in the area in which your flying. But I can switch from No Path when faster then 100 mph and then switch to a Path with Wide2-1 when slower then that speed, like when on approach to land. Ray
