KNOW MORE ABOUT SOS SIGNALS
What is a SOS signal?
SOS is the international Morse Code distress signal. It is used when a person is in trouble and
needs help. Morse code is a way of sending and receiving text information in a series of on-off
lights, clicks, tones etc. that is a secure and faster way of communicating. These on-off or long
and short signals are called as dashes and dots.
SOS distress signal is expanded as three dots, three dashes and three dots again. This method
came into existence in around 1905 and since then became a life saving communication
technique in a lot of radio communication fields.
SOS signals and walkie talkies
Walkie talkies are very popular radio communication devices and help transmit voice signals via
radio channels to one or more recipients within specified distances.
They are a must have for people who involve in activities like trekking, camping, climbing,
mountaineering, exploring newer places etc. in groups or as pairs travelling to places that are not
habituated and not covered by cell phone signals or telephone lines.
Without cell phones, communicating to the rest of the group becomes difficult when there is an
emergency or in case one or more people get separated from the group.
Being stranded in the middle of the forest with no supplies to eat or drink and no means of
communicating with the rest of the world is a very risky and even life threatening situation!
How do walkie talkies help?
These days, walkie talkies are equipped to deal with emergencies by alerting the user of
impending natural disasters and help reach out to the receivers in case the person is in trouble.
SOS radios or SOS walkie talkies are devices that help know the exact weather condition, light up
the path way and send emergency distress signals to other when in need.
Weather alerts
People who indulge in physical and adventurous activities usually plan it for several days and
sudden changes in weather forecast or natural disasters can make travelling risky. These walkie
talkies are always tuned to the local weather forecast station and keep the user informed of
impending danger.
Torch lights
These are available in a lot of walkie talkie models these days. The strong beam of light is a
blessing for people who travel in dark and is a very useful feature to have in a walkie talkie.
Emergency distress signals
These radios can send SOS signals to the rest of the group or to selected people who are tuned
in to the same frequency and keep flashing the signal even when the person is physically unable
to operate the device. There are few high end models that also have GPS to allow track the
person's location when in need. For models that are fully charged, these SOS messages can
even keep flashing for days until help is received.
All these options have changed walkie talkies from being mere toys to life saving communication
devices. For professional trekkers and adventure enthusiasts, investing on a good pair of walkie
talkies is a must. It keeps the person safe, informed and makes the whole process easier.
