When you
hear a
ham radio operator identify themselves by their
callsign, you can tell where they are by the
prefix of the callsign. For example, GM5XX is located in
Scotland because of the GM part of the callsign. If a radio operator is not home (called being mobile), then GM5XX/3D2 is used. The 3D2 says that this
Scottish laddie is in
Fiji or Conway Reef, near Fiji.
