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!
