How many days until International Amateur Radio Day?


International Amateur Radio Day is celebrated on April 18 every year in order to mark the day when all amateur radio operators globally go on air and celebrates International Amateur Radio Day.

History of International Amateur Radio Day

Club members and ham radio operators are the same, who will spend the day performing and discussing amateur radio. Assessment of the operability of stations and discussion of the interests of amateur radio operators, the public service role they and the club perform by providing contact information from the local calls before natural disasters... are some popular and interesting topics.

Ham Radio became more and more popular because of its convenience. When using Ham Radia, you do not need to use the mobile phone network or the Internet to communicate. Operators are especially important during disasters when normal communication channels fail. For example, the Amateur Radio Service continued to communicate with New York City agencies after their command center was destroyed in the 9/11 tragedy. Radio Ham also came for relief during Hurricane Katrina, where all other communications failed.

In the early 1920s, the first shortwave spectrum was founded by amateur radio experimenters, not "wasteland", could support worldwide propagation.

The American Radio Relay Federation (ARRL) showed some reasons why amateur radio operators are called "ham radio" operators:

The first wireless operators were fixed telegraph workers who left their offices to go to sea or manage coastal stations. They brought with them their language and much of the tradition of their age-old craft.

In some early days, every station took the whole spectrum with its wide spark signal. In addition to government and coastal stations, a growing number of amateur operators are competing with each other for receiver time and signal.

Many amateur radio stations are very active. Two amateurs, working together in town, could effectively interfere with all other activity in the area.

Some commercial operators will use “hams” to call radio interferences. Amateurs, who are unfamiliar with the true meaning of “hams”, chose and applied hams. As the years have passed, the original meaning has completely disappeared.

In April 1925, the International Amateur Radio Union was established in Paris. These intrepid explorers have discovered that the shortwave spectrum that amateurs use radios to transmit and receive can link people all over the world, something no one had thought of before. The group of radio researchers proved this theory wrong with an experiment and banded together to advocate and protect bandwidths that would serve the community of radio enthusiasts.

Since, International Amateur Radio Union has worked hardly to expand the range of bandwidth to radio fans and has increased with a lot of members from 25 countries over the world. Amateur Radio has only developed quickly from those early days with more than 3,000,000 licensed operators spreading their voices globally today. Through this medium, people from different countries and cultures were able to spread ideas at a rapid pace, long before the ability to email or video chat became possible.

How to celebrate International Amateur Radio Day

International Amateur Radio Day organizes events worldwide to celebrate this great invention and bring together those who still see the value in being able to skip a radio station across the ionosphere thousands of miles away and unite the two left ground together through a wave of energy oscillations. If you've ever watched or worked with an amateur radio station, take some time on International Amateur Radio Day to learn what the station is for and what can be learned about getting familiar with a beginner to begin to explore the world of radio amateurs. International Amateur Radio Day is a wonderful opportunity in order to explore the Amateur Radio world and find and make new friends and communities that exist all over the world, so what are you waiting for?
