Good info.  How many hops do those packets take?  In most areas
of the country, 40 to 80 miles is routine with one hop... And a
good home antenna (at least here in Maryland...

Agree, smart beaconing should apply to WX to.  I should have
included that in my paragraph.  The original APRS did that.  WX
beacons were decayed just like all other packets.  Changed
weather was beaconed immediately.  Unchanged weather doubled
between each following transmission.  (Wind direction changes
would not trigger a new start to high rate if the wind speed was
low).
