The 2023 Jota Joti activity held by the West Kalimantan Regional Kwartir on 21 - 23 February 2023 was a very impressive activity for me, how could it not be that this Jota Joti activity is an activity that I think is very useful for today's young people to learn more about equipment radio and also introduce young people to Safe From Harm which aims to educate young scouts to be careful when using the internet. one of the things I learned was how to use satellite radio communication tools, various types of communication were explained, such as communication using SSTV which is useful for sending images with sound waves, then rattlesnakes which are sent via the ISS or international space station, I also didn't miss the use of the radio itself. learn how to enter frequencies and also the most important thing about the phonetic alphabet which is very commonly used in satellite radio communications. This activity was attended by approximately 20 people from all regions of West Kalimantan.
