SAILOR, 6390 Navtex Receiver

The SAILOR 6390 Navtex Receiver receives Navtex messages on the international Navtex frequencies 490 kHz, 518 kHz and 4,209.5 kHz. It can hold 2000 messages per frequency. Messages are not affected by a power cycle. Untagged messages are cleared from the message log after 661 hours, you can tag messages for later viewing. You can customise which stations to receive messages from and which message types you want to receive. The unit has an alarm relay which is only activated if a message of category D is received (i.e. SAR, Mayday relay, Pirate attack etc.). The SAILOR 6390 Navtex Receiver is always on when powered. With its LAN interface the transponder and the display can be separated, giving access to the Navtex information available where it is needed.
