  1. D-StarLet A web-based text messaging application using ICOM D-Star digital data technology.

  2. D-StarLetfeatures: • One "master/server" computer is connected to the radio via a standard serial port, using Sun’s Java software, and Apache’s Tomcat web server (all are free software). • A web browser on the "master/server" computer (as well as optional web browsers on multiple "client" computers on a local network) is used to perform all messaging tasks.

  3. D-Star (GMSK) D-Star radio (optional) (optional) (optional) Web browser Web browser Web browser LAN • Web browser • Also running: • D-StarLet Java servlet • Tomcat web server Serial port

  4. D-StarLetclient features: • Multiple browser windows on the same or multiple computers on the local network can be used to create, send, receive, and manage multiple messages in parallel. • The status of all incoming and outgoing messages are displayed in any browser window on any computer on the local network. • Messages can be printed on any computer using the browser's normal printing function. • A communications log of all messages sent/received can be viewed on any browser.

  5. D-StarLetserver features: • Each incoming and outgoing message is automatically saved as an XML text file on the server computer. • D-Star radio communications are performed by a Java servlet running in the background on the server, independent of any browser.

  6. D-StarLetserver requirements(hardware): • Pentium 233 or equivalent. • 96MB RAM. • 100MB available hard disk space. • An Ethernet network card, if client computers are also used. • An available serial port.

  7. D-StarLetserver requirements(software): • One of the following: • Windows 98 or higher. • Recent Linux/Unix. • Apple Mac OS 10.1 or later. • Apache's Tomcat web server, version 5.5.10 or later (free). • Sun Microsystems' Java JDK (Java Development Kit), version 1.5 or later (free), plus Sun’s JavaComm package.

  8. D-StarLetclient requirements: • An Ethernet network card. • Any operating system (e.g., Windows, Linux, Mac OS) that supports network connections. • Any browser (e.g., Internet Explorer, Netscape, Firefox, Opera). • No other software (e.g., Java) needs to be installed on the client.

  9. D-StarLet advantages (1): • The composition of multiple messages can be made in parallel in multiple browser windows, eliminating the need to save one message being composed, in order to work on another one. • Messages can be created as a draft by one person, and then reviewed and sent by another person on another computer on the local network. • Incoming messages require a separate step to mark them as "received". This feature ensures that incoming messages are not forgotten.

  10. D-StarLetadvantages (2): • Each incoming and outgoing message is automatically saved as an ordinary XML text file on the server computer. • Since the entire program is open source, maintenance and/or upgrades are not dependent on any relationship to the author.
