"WIDE1-1" is the new substitute alias for home fill-in digipeaters 
(replacement for "RELAY").    This is the only alias home digis (which 
frequently use old non-APRS-n-N-savvy TNCs that don't do true n-N 
callsign decrementing) should respond to, other than their own actual 
callsigns.


"WIDE2-1" ensures that only "real" WIDE area digipeaters with true n-N 
capability to process any value of N will respond, and then for only one 
hop.   (Presumably, from a balloon's altitude, one doesn't need 
low-level RELAY-type home digi fill-ins).
