RMS Express

RMS Express is the preferred Winlink 2000 (WL2K) radio email client because it supports all new WL2K features, including the Winlink Hybrid Network and Secure Login to prevent unauthorized access to your radio email account. RMS Express is designed to be most easily used by single users with a single call sign but it may also be used with one or two tactical addresses or alternate callsigns. It supports a wide selection of TNCs and multimode controllers, the sound card mode WINMOR, HF Pactor, SCS Robust Packet, VHF/UHF AX.25 packet radio, and direct telnet to WL2K CMS servers or RMS Relay (for amateur radio High Speed Multimedia [HSMM], Broadband HamNet, D-Star DD mode, internet, or other TCP/IP networks).

RMS Express is built by the Winlink Development Team for use with the Winlink system and leverages its features with simplicity as the prime design objective. It uses the B2F extension radio transfer protocol that supports attachments, multiple addresses and tactical addresses. RMS Express may be used peer-to-peer (connecting directly via RF to other RMS Express or Airmail 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 feature to help determine which of the participating Winlink RMS gateway HF stations are best to connect to from anywhere on earth.

RMS Express may be used as a client for emergency communications. It has some special features for EmComm, such as HTML/CSS forms creation and formless content transport, plus a growing library of pre-created forms to use. Before adopting RMS Express as your program for EmComm, please check with your local EmComm group for their plans. This may be your ARES, RACES, MARS etc. organization that will be responsible for providing training and support.

System Requirements: Microsoft-supported 32 or 64 bit Windows OS (Windows Vista, Windows 7, 8, 10 or Windows 2003 Server, or later, or under Windows on Apple Mac machines using a VM engine or dual boot arrangement. Windows XP is not recommended or supported. The program makes minimal CPU demands with the exception of WINMOR operation. The heavy DSP demands of WINMOR require a computer of at least 700 MHz Pentium/Celeron class and at least 512 Meg of memory. It runs fine on all modern computers and Windows tablets. If multiple applications are running concurrently, we recommend a fast computer with extra RAM.


Customizable HTML Forms allow input and reading on exact-likeness or just "pretty" forms in a browser using form widgets like selection boxes, check boxes, and more. Further, lightweight form contents can be transmitted without the form itself, then automatically read at the other end inside the electronic form with a browser. And, the forms and templates are also transportable across a radio connection as attachments, or retrievable by radio from the Winlink Catalog, or downloadable from the Winlink Forms Library.
