RMS Express is the preferred Winlink 2000 (WL2K) radio email client. It is in active development by the Winlink Development Team and is well-supported. RMS Express is designed to be most easily used by single users with a single call sign but it may be used to access one or two preset tactical addresses or alternate callsigns. RMS Express supports a wide selection of TNCs and multimode controllers, the new sound card mode WINMOR, as well as support for HF Pactor, SCS Robust Packet, VHF/UHF packet and direct telnet to WL2K CMS servers (for amateur radio High Speed Multimedia [HSMM], D-Star DD mode, or internet).
RMS Express is built for use with the Winlink 2000 system and leverages its features with simplicity as the prime design objective. It uses the B2F protocol that supports attachments, multiple addresses and tactical addresses. With the WINMOR mode RMS Express may be used peer-to-peer (connecting directly via RF to other RMS Express clients). RMS Express also contains manual and automated GPS position reporting abilities, support for the Winlink catalog of downloadable weather, information and help bulletins, Saildocs and Globalmarinenet for obtaining GRIB files, and a propagation prediction program to determine which of the participating Winlink RMS gateway stations you can connect with from anywhere on earth.
RMS Express may be used as a user client for emergency communications. However, before adopting RMS Express as your program for EmComm, please check with your local EmComm group for transition plans. This may be your ARES, RACES, MARS etc. organization that will be responsible for providing training and support.
