April 23rd Activity for Amateur Radio Operators!

We experienced a natural disaster that shook us all deeply in the past months. Although our physical wounds begin to heal as the days go by, it will take time for the psychological wounds, especially on children, to heal. However, as one heart in our beautiful country, we are hopeful and strong for the future.

This month we will celebrate an important day, especially for children. We celebrate the 23 April National Sovereignty and Children’s Day, which our great leader Mustafa Kemal ATATÜRK presented to Turkish and world children right after the Great War of Independence…

The first holiday in a country that is trying to be renewed in the face of all the suffering, challenging conditions, and subsequent impossibilities during the war; It is one of the essential steps for the strong Turkey of the future and has been a significant source of moral motivation for children.

As MoEP, we wanted to create a similar source of motivation together with our science volunteers and amateur radio operators and to bring our children, who are our future, together with space sciences and leave a beautiful memory that they will remember in the future.

This study will also be an experience for operators who develop equipment for QO-100 satellite communication, which is allowed to be used due to the state of emergency for amateur radio operators. Participants will also have the opportunity to perform tests such as hardware endurance, antenna systems, hardware performance, heating-cooling, etc., during the long-term activity.

Continuing our article, we share the list of our primary stations that will be linked to the satellite, the general steps to be followed during the preparation period for the event, the things that can be done during the hardware testing phase, and the necessary information. Amateur radio operators participating in this activity will be entitled to receive a certificate.

MoEP Stations, which are connected to the QO-100 Amateur Satellite
