The original APRS (APRSdos) has several displays and functions 
for RF packets that makes the user intimately aware and 
intune with the local RF network:

- ANALYZE HOPS - shows how many hops each digi is from you
  and also displays the range circle for each digi with colored 
  circles.  All 0 hop digis (direct) in red, all 1 hop digis are 
  shown in Yellow, all 2 hops in blue, etc..

- ANALYZE USERS - shows how many hops each user is from you
   using the same color scheme and also drawing their PHG
   circle.

- ANALYZE COUNTS - shows the packets per hour from each
  station for the last 24 hours and sorts it.  Instantly you can
  see the stations causing the highest load on the RF network

- ANALYZE DIGIS - shows the percents of local RF users using 
  each type of path (RELAY, WIDE, and each of the WIDEn's)

- ANALYZE TRACE - will trace on the map (digi to digi) the 
  exact path a stations packet took to reach you...

- ANALYZE LINKS - Draws lines from every digi to every station
   it hears direct.  Very easy to see actual coverage.

- ANALYZE PATHS - lists the users of each selected type path.
  ie, A-P-RELAY will list all local RF stations using RELAY

- ANALYZE ALOHA - will compute from your station, your ALOHA
  range.  That is, a circle that contains the number of RF stations
  that constitute a 100% full network as viewed from your station.

- ANALYZE TRAFFIC - will draw white lines on the map between 
   end points of all messages.  Makes it easy to see who-where 
   is talking to  whom-where, and all active QSO's.
