These ports are overwhelmingly obsolete.   Users are now being urged by all 
server operators to use the user-defined port 14580 filter port instead.    On 
port 14580, you can custom define a feed that meets your requirements far more 
precisely.  You can ask for a specific radius around a given lat/long point (or 
a given callsign), a rectangular box bounded by a pair of lat/long points, by 
callsign or callsign prefix, by APRS symbol type and much more.

You can combine multiple filter expressions to, for example, bound your home 
location or state with a box of a given size + a circle around a friend's 
location on a trip at the other side of the country.    You can also EXCLUDE 
various combinations of symbols, areas, etc.

The user-defined filter is vastly more versatile than the classic fixed feeds 
and can tremendously reduce the bandwidth consumption by not sending you a 
firehose of stuff you DON'T want.

Full details on my web site at:

JavAPRS Filter Port 14580 Guide

Note that in UIview, the command line that begins with "filter" and then some 
expressions is entered into the field "Extra log-on text" on the "Setup, APRS 
Server Setup" page.   You will also have to hit "Insert" and enter at least one 
new line into the APRS server list, specifying a servername:14580  such as:

.        aprsca.net:14580

All the APRS servers, both the classic tier 1 and all the tier 2 servers, now 
support (and encourage the use of) the port 14580 filter port.
