From country leaders to the leaders of the world’s largest companies, amateur radio unites people of different backgrounds and professions. Who are the most famous amateur radio operators?

Guglielmo Marconi was an Italian inventor and the person who first adapted radio waves into a functioning communication system. After the initial idea of interconnected telegraphic systems, many people began experimenting with possibility of making it wireless.

At the break between 1800’s and 1900’s wireless was completely unregulated, as nobody really knew how it worked with all the transmitters and receivers, resulting in many people experimenting with their transmitters and receivers.

It’s hard to tell who was the world’s first radio amateur. Rumors are that it could have been M.J.C. Dennis from London, UK. Influenced by Marconi’s experiments, Dennis reportedly built first non-professional wireless station in the world in 1898.

The interest has grown more and more ever since. Nowadays the field is regulated with licensing and the hobby has become well-established. Red Pitaya recognized the interest and built Hamlab, which includes everything any ham radio operator needs for its daily operations. From country leaders to the leaders of the world’s largest companies, amateur radio unites people of different backgrounds and professions.
