Callsign Lookup

Have you ever heard a callsign and said "Gee, I wonder who that is?" Well, now you can find out. There are multiple methods of finding out who a callsign is. The two methods discussed here rely on the web site lookup.

The easiest method is to send an APRS numbered message to WHO-IS with the callsign as the only text in the message. This returns a one line message with the information you are looking for. If you want full information, add "f " before the call to get a multi-line response. Message text is case-insensitive.  Examples of both commands (message number sequence {xxxxx is removed):

        AE5PL-10>APRS::WHO-IS   :ae5pl
        AE5PL-10>APRS::WHO-IS   :f ae5pl

WHO-IS is a javAPRSSrvr client written in Java and uses XML to access the database. You can also use WHO-15 (fifteen) to accommodate those clients and IGates that do not support non-AX.25 SSIDs. Both servers perform exactly the same and may be used interchangeably.
