Data Comms

This page is dedicated to providing the most current information on data communications in use in Connecticut.  Packet radio is a vital communication technique for data communication.  The current Flexnet/FBB system is the only 100% RF system we have today.  It provides coverage of much of Connecticut and its coverage is expanding.  The Flexnet/FBB system can handle text-only messages, NTS traffic, and bulletins.

The Winlink 2k system is more e-mail based, allowing for attachments of status reports and other small attachments.  Today, all state Regional offices can access the Winlink2k server on Box Mountain through 100% RF links.   This means they can exchange messages with each other, even if all Internet connections are down.  This means that all the State offices will have two 100% RF systems for exchanging digital messages, each system providing digital communications support and serving as a backup to the other.

If a user station is configured for Flexnet/FBB they can use Winlink2k.   If a user station is configured for Winlink2k they can use Flexnet/FBB.   While the two systems work somewhat differently, the underlying user technology is the same.  We encourage users to become familiar with both.

And, finally, RMS Express is a Winlink 2000(WL2K) radio email client.  It is intended to be used in applications that need to support only a single user and call sign but it may also be used to access one or two preset tactical addresses or alternate call signs.  RMS Express includes support for other methods including direct telnet to WL2K Common Message Servers (CMS).

    A. Why Winlink?
    It allows a ham to send email from any location within contact range of an RMS Hub.

    B. Why email?
    Because, in today's world, almost everybody seems to know how to write an email message.  It allows the receiver to get the message EXACTLY as the sender intended.  There is no mispronunciation, no misinterpretation, no mistakes that frequently happen with voice messages.   (There's also that old adage, “If it ain't on paper – it never happened!”).  You can send email to ANY valid email address, @xxx.com, @xxx.net, @xxx.gov, @co.ozaukee.wi.us.

    C. Security?
    It is relatively secure.  The Federal Communications Commission (FCC) does not permit encryption on amateur radio frequencies.  On the other hand, Winlink uses a compression technique that doesn't allow the frequency watcher to read the message – it looks like garbage.  (The local Winlink guru has, for years, offered a substantial prize to anyone who could intercept and read a message – no one has claimed it.)


There are some recommendations on digital voice for VHF, UHF and up.  Read more about it on the recommendations page

RMS Packet Gateways

The following RMS Packet Gateways are now available for use.  It is suggested that if you are not already a user of RMS Packet that you check out http://www.winlink.org to learn how to activate your own Winlink.org email address.  The site has valuable information as well.

Software recommended is RMS Express to use the system.

The project is a joint venture between CT DEMHS, the CT State Police Radio Club (W1SP) and CT ARES.

W1GTT has been working almost three (3) years to get the project completed.

Please use it and report any problems you encounter.
