What Is An Emergency Radio: It’s Modern Value
The invention of the radio, as we know it today, is enveloped in rich history. Looking back, with all the advanced gadgetry we have today, you may find the old methods amusing.
Before the 1800’s, transferring a signal or current from one point to another without copper or any medium was impossible. The discovery of electromagnetic waves and invention of the radio changed everything they used to believe.
With the availability of radio channels on the internet, radio technology can sometimes be misinterpreted today, especially by the younger generations since only a few millennium babies are quite knowledgeable about it. But what is an emergency radio?
Before we answer that, let’s take a peek at how we ended up with this amazing technology. You will be surprised how it all started!
Invention of Radio
The development and invention of the radio can be attributed to a few great minds in the history. However, we can pinpoint James Clark Maxwell for his astounding works and the prediction of the radio waves. The discovery of natural radio waves eventually led to recreation and manipulation of it.
With the succeeding works of Hans Christian Ørsted, Michael Faraday, Joseph Henry, and André-Marie Ampère, it led to the improvement of the radio technology. It involved scientist picking up trails of other predecessors and reverse engineering their works to find out where they went wrong and got it fixed.
Seeing the value of radio frequency in telecommunications, many inventors followed suit as if they are in a race to discover the next golden technology. These led to the remarkable innovations and manipulation of radio frequency that can be used to transmit in extensive coverage to be interpreted by radio transceivers.
Types of Radio Frequency
When we talk about the analog radio receivers that your grandfather was fond of, we are talking about the two popular broadcasting types involved; AM or Amplitude Modulation and FM or Frequency Modulation. Growing up, I have associated the AM radio with adult stuff as it mostly broadcasted news while the FM radio with younger generations as it mainly aired music, which I have come to enjoy. Undoubtedly, it’s one of their significant differences.
AM Radio Station
The AM stations were the earliest form of broadcasting. This may be the reason why they still broadcast the old stuff! Kidding aside, the real reason is quite well-thought of. The AM signal is quite susceptible to interference, and because of this, they specialized in talk radio, news and other spoken word formats.
It also transmits signals at much lower frequencies. In the Northern Americas, the AM radio frequency range is 525Hz to 1705kHz.
FM Radio Station
Edwin Howard Armstrong took radio broadcasting to another level. He was pestered by the radio frequency interference which disrupted the signal of AM radio broadcasts, so he took it upon himself to find a solution, and that was when he invented the FM radio.
He tapped the very high-frequency range or VHF and found out how much more efficient it is compared to AM radio. It also revolutionized the already high-end technology of 1900’s.
There was less interference with FM radio, and a higher quality of audio signal can be broadcasted through VHF.
What Is an Emergency Radio?
Do you still remember how big analog mobile phones used to be? Every succeeding year, it had gotten smaller and smaller until it was barely pocket-sized.
Likewise, have you observed how thin the newer models of laptop computers become every succeeding year?
Well, it happens to most useful gadgets. Everything gets miniaturized by technology. Radio receivers used to be as huge as refrigerators!
On a serious note though, an accurate comparison that would describe radio receivers of the 1900’s would be a microwave oven. Well, if you think that’s not too bad, let me ask you this: Can you put it in your pocket? Right.
Emergency radios are gadgets designed to remain functional in cases of emergencies. If telecommunications and power suddenly become unavailable, an emergency radio can mean life in dire situations.
Value of an Emergency Radio
In areas where there are frequent storms, tornadoes, earthquakes, zombie attacks, and other life or death situations, an analog emergency radio can keep you updated. Listening to emergency broadcasts or weather updates can help you know what your next best move is and give you ample time to do the necessary preparations.
Modern Emergency Radio
Old emergency radios have only had a single function in case of an emergency, while modern emergency radios have more features and added values to them. Well, in an emergency situation, it would be nice to have more than just a radio, right?
Modern emergency radios are now equipped with lights, AM, and FM. They are also either battery-operated or electronic- or solar-powered.
Some models are equipped with crankshafts to charge; some can even be charged and used as power banks. These models come in handy when you need to charge your mobile phones during a power outage.
With our current technology, it is not impossible to put all these features and more in one pocket-sized emergency radio, making it the most sophisticated emergency radio there is.
From the Past to the Future
Isn’t it fascinating that the current technology rooted from something that was very primitive? Who would have thought, back then, that the technology they were dabbling on would revolutionize the technology of the second millennium?
Even with all the advancement in today’s telecommunications, an analog AM/FM radio still has its unique value not just in case of emergencies but in our day to day activities as well. Having one radio readily available at home, in your car, in your workplace, or anywhere you could think of would prove useful in cases of emergencies.
We would not know when will we be in that situation. But having some means to communicate or receive information with can be a lifesaver. What is an emergency radio? Simply put, it is a lifeline in an emergency.
