On the Open Sea!

               Lifeboat radiotelegraph transmitter receiver (LRTTR) was used as a last resort safe guard. When a vessel sinks communication may be hard to make aboard. When survivors would get to the lifeboat this device would be the relay for them to be saved.  It is designed to float so even without the lifeboat, this could be found floating about to maintain a connection. Many are a bright orange to help create a contrast so a passing by ship or even aircraft could spot it. This is by far one of the coolest communication devices we have on display! Lifeboats are always seen as a way to just get to shore and possibly stay dry. Using this device would make navigating much simpler in the sense of the connection can be stronger if you are closer to shore or another vessel.

To use the LRTTR a ground wire would be placed in the water while the antenna is raised. This device runs by hand crank to send and receive messages. Morse code is the only source of communications on this device. It has built in key and headset to hear the sounds as they transmit. It can also send an automatic distress signal to all receivers in automatic mode.

As communication in the world developed each piece of equipment made had a strong purpose and live out its lifespan. Morse code had been the biggest development in communications for seafarers. The integration of morse code on devices such as this would only make it much more seafarer and easier to be found.

We currently have a Radiomarine Corporation of America – Model: ET-8053 LRTTR on display. Come on down and take a first up close and personal look!
