[aprssig] Just my 2 cents worth on smart beaconing

[Julian, G4ILO]

Not wishing to be too controversial but I thought that APRS was not a
position tracking system and the main purpose of sending position
beacons was only to show you are in a particular area. I never use
smart beaconing and find a beacon interval based on distance travelled
or time elapsed to be adequate in all situations.
