The Thrane TT-6301A – SAILOR 6301 Control Unit DSC Class A is a modular and flexible MF/HF radio that can be customized to your specific needs for MF/HF communication on work boats, high seas fishing vessels and merchant vessels of all kinds. It offers simplex and semi-duplex SSB radiotelephony in the maritime mobile frequency bands from 150 kHz to 30 MHz. Services include voice transmissions, watch function, DSC operations (Distress calls, position info, Distress relay and more) and AM Broadcast reception.

The large display shows Rx and Tx frequencies and status, MMSI number, position information, system and channel properties, including indicators for transmission power and received signal strength. It is easy to read from almost all angles and the display light can be adapted to dark environments. Red text is shown on a black background providing good visibility in low light conditions while protecting night vision.

DSC operations are made using the four soft keys next to the display. The MF/HF radio can replay the last 240 s of received voice. This is a useful feature to minimize misunderstandings and to record audio when the radio is unattended. The SAILOR 6301 Control Unit has an Ethernet interface to connect to other equipment for control, monitoring and printing.

The SAILOR 6301 Control Unit is available as a basic MF DSC radio that can be upgraded with an HF DSC option and/or a telex option. Telex is sent using the SAILOR 6006 Message Terminal.
