(January 9, 2026)  PACTOR Customers!!  We are working directly with SCS to bring the new Dragon modems into the USA as soon as possible.   If you are looking for PACTOR modems, cables, etc please reach out to use via email for now ([email protected]) and let us know what you need and how quickly you need it.  This will help us determine how best to stock the new hardware items.  Thank you!!

Icom’s M803 and other Single Side Band HF (high-frequency) marine radios are versatile communications solutions offering GMDSS compliant distress calling, ship to ship voice communications over hundreds or thousands of miles of distance, access to free weather data such as navtex, weatherfax, and audio reports, and global access to email and weather gribs when paired with a Pactor modem.  With minimal to no ongoing costs, a Marine SSB can be a communications lifeline for boaters who are travelling the worlds oceans.

Sea-Tech Systems maintains the most complete packages and options for marine SSB installations on leisure boats.  With the best brands including ICOM, SCS-PACTOR, GAM Antennas, Radioteck’s patented KISS-SSB RF Counterpoise, and Metz Antennas, we have everything you need to successfully install the HF-SSB system you desire and take full advantage of the voice, email, weather, and distress functionality it provides while sailing the worlds oceans.

The cornerstone of Sea-Tech’s offering is the complete SSB Email and Weather package which has everything you need for SSB radio communications onboard including PACTOR email, Weatherfax decoding, DSC Distress functionality, with a choice of RF grounds and transmitting antennas to make your installation easy.  We even program the M803 radio with DockSideRadio’s channel list just like DSR did for their customers.

Already have an HF or Marine SSB radio but want the ability to send/receive emails, download GRIB files, and more, for free at sea and/or access emails without satellite airtime?  Add a PACTOR4 Dragon modem to your existing radio to start sending and receiving data faster than an Iridium Go! at practically no usage cost.
