Every amateur has different uses for packet. Some view packet as a tool to enhance their overall enjoyment of Amateur Radio. Others take it further, using packet as their primary means of communication. Some bulletin boards offer additional services such as electronic call sign directories and magazine bibliographies. DX PacketClusters support other useful features as well.
Many satellites function as orbiting bulletin boards, relaying packet messages around the world.
Others transmit images that you can display on your computer screen. Almost any computer can be used with the TNC or MCP of your choice. All that's required is a compatible terminal program. For 2-meter packet operating, fancy antennas are not required. A simple ground plane is fine for most areas.
