KWRTTY V1.1.3, released on February 4, 2008, is a freeware RTTY reception program designed for Windows operating systems (Win95 and higher, requiring a minimum 133 MHz Pentium processor and 32 MB RAM). Its primary function is to decode and log amateur radio **RTTY** transmissions, including the capability to set up a private RTTY mailbox that records only messages addressed to the user's callsign. The software is specifically optimized for receiving and logging marine weather reports from the DWD (Deutscher Wetterdienst), categorized by sea areas, making it particularly useful for sport boat operators. The duration of logging is limited only by available RAM. For its core functionality, KWRTTY requires the **MMTTY-Engine** by Makoto Mori, JE3HHT, as an interface between the sound card and the program. This engine, also freeware, needs to be copied into the same directory as KWRTTY. The program's design focuses on continuous logging of specific RTTY content, offering a specialized tool for both general amateur radio RTTY monitoring and dedicated weather report reception, distinguishing it from more general-purpose digital mode software.

This page provides information on how amateur radio, or 'Ham' radio, is used by the yachting and small boat community for communication and weather information. It explains the global operation of amateur radio, regulations within the U.S., and the role of the American Radio Relay League (ARRL) in licensing and training. The page also highlights maritime 'nets' where Hams exchange weather reports, using voice and digital modes. It encourages establishing webpages for nets and mentions the MAROB and SKYWARN Programs for marine observation and severe weather reporting. The content is useful for hams interested in maritime communications and weather reporting.
