APRS Servers

Listed below are all known (to me) APRS servers. Please contact me at pete@ae5pl.net with any corrections. I have listed only the primary full feed port when other standard ports are supported.

javAPRS users will normally want a port with a history dump. All bidirectional client software MUST use ports that do not have a history dump. I recommend using rotate.aprs2.net for javAPRS data feeds as this will spread loads across the various servers and will keep your web page from being dependent on a single server for the APRS data feed.

Clients and IGates should use filtered ports, if available. Servers (such as javAPRSSrvr and aprsc) should connect directly to the core servers. Do NOT use near-full-feed filters such as t/poiw on non-core servers. Please respect the resources of your fellow hams.
