WHAT!!???  This totally breaks APRS as a messaging system.  Where did this
come about.  It also breaks vicinity tracking, another very powerful APRS

There are MANY times and certainly in times of stress and emergency and
backup comms when a position is not possible or easy.  How did this creep
into the APRS system?

How do we fix it?

The criteria for IGateing back to RF is "LOCAL" meaning only that the
station was heard DIRECT or on the first hop.  (though this can be a
variable in remote areas)..
