What does ham radio stand for? A lot of people have heard of the term “ham radio” but don’t know what it means. Ham radio is simply a coined term for “amateur radio.”
Amateur radio is a type of radio communication device designed primarily for personal use by persons or small interest groups for purposes of informal messaging, personal training, recreational activities and urgent communications.
The word “amateur” is simply for distinguishing between more serious, commercial and public broadcasting like public TV and radio, or professional two-way communication exchanges like is used in the navy, aviation, fire services and so on.
Historical Background Of Ham Radios

The word “amateur” is simply for distinguishing between more serious commercial and public broadcasting like public TV and radio, or professional two-way communication exchanges like is used in the navy, aviation, fire services, and so on.
Historical Background Of Ham Radios
Amateur radios have a rich historical background that stretches back to the early twentieth century.
They first started becoming popular in countries like the United States, and Canada and the advent of amateur radios have been the bedrock for many inventions that came on after, contributing significantly to science and technology in many sectors and industries to include the military, telecommunications, construction, engineering, etc.
The coining of the word “ham” came on later as a mock term used to tag amateur and untrained radio operators. However, decades later, since the word’s coining, the ham radio enthusiast community has grown to embrace and formally adopt the name, free of its derogatory meaning.
Equipment Needed To Build A Ham Radio
Building a ham radio from scratch entails just about the same rudiments as any other electronic device that uses radio technology. But before starting, there are vital factors that need to be considered before you can begin building a ham radio. These factors include:
For what purpose you intend to use the ham radio. Is it for long-distance communication or short-distance two-way communication?
In either case, you would have to choose the equipment and paraphernalia that would match your intentions to have a better utility from your ham radio.
Where will you be operating from? Do you intend it to be a mobile? For instance, are you going to be working from a vehicle such as a van? Will it be operated indoors or outdoors?
These are vital questions that should be asked and answered before starting out building a ham radio. Thirdly, you need to consider band coverage.
Typically, ham radios are less demanding on band usage and other peripherals. They can also stay very active for very long hours of the day.
Now we have covered all the factors that need to be in place before building a ham radio. We will, however, outline the equipment and tools you need to start building from scratch.
Below are the essential tools you need to develop a working ham radio station. Some of these tools are optional, while other very merely part of the basic requirements:
A receiver: Acts like a scanner that you can use to scan for various radio channels and frequencies
A transceiver is a coined term used to explain a piece of equipment that acts as both a transmitter and a receiver. It is an optional tool as you can do without it.
Antenna: This is one of the essential tools of all. A good antenna helps you sustain connection over a long period.
Antenna Tuner: This is simply equipment that gives you the option of transmitting on as many bands as possible. Antenna tuners are also optional.
Power Source: This could include batteries, solar panels, or AC devices.
Licensing: This is the last part of the hurdle. You can’t just start operating a ham radio without first getting the proper license.
What does Ham radio stand for?|How do Ham Radios work?
Ham radios follow a simple process of transmitting and receive. There is a source transmitting signals while the ham radio at a station is at the receiving end of the communication exchange.
Ham radios work using a concept known as propagation. Propagation is simply a phenomenon that explains radio signals’ movement through space, being deflected and thrown from one obstacle to another until a listening radio antenna can trap it.
Ham radios watch out for obstructions that can hamper the flow of radio signals in the air, such as stormy weather, smoke, haze, and snowy conditions.
You should note that atmospheric states have a significant role in the smooth or bumpy radio signals flow in space.
The weather state at every point in time is also a determinant factor of how far a radio signal can go.
Like in extreme weather conditions like the ones discussed above, you can expect to have poor service in radio signal propagation.
That is why it is an essential part of the whole communication process that ham radio operators must always have a robust and high-quality antenna that can listen out and boost radio signals even in adverse weather conditions.
There are few key terminologies that you need to understand as far as ham radio technology is concerned. They include:
A radio wave is simply another form of energy that moves through an electric or magnetic field in space.
Tiny particles called electrons move through the electric and magnetic fields in different modes, and they carry radio waves along with them.
The radio spectrum is a small space in an electromagnetic field dedicated to communication exchange and radio transmission.
As the name implies, repeaters repeat unclear or otherwise lost signals during transmission to make them more transparent or travel much further.
Wavelength and Frequency
A wavelength is simply a length in the distance that a radio wave can travel in one cycle period, while You can measure the frequency of a radio wave in how many cycles it can make in a second.
A radio filter is simply a term used to explain how unwanted and obstructive frequencies and radio signals are being filtered away from the required ones to make for better and more precise communication exchange.
Modulation is a way of encoding instructions into a radio wave to be transmitted over an analog radio signal.
