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 a 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.

    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 information. You can also use WHO-15 (fifteen) to accommodate those living in areas where the IGate is either out-of-date or the sysop has turned on callsign filtering for gated packets. Both servers perform exactly the same and may be used interchangeably.
