KG-STV Activity Result

All of the pictures sent to the “Life on Mars through the Eyes of a Child” painting activity were sent to space at the end of days of work, and one more activity was completed successfully. We wanted to share the details and background of activity with you. First of all, in our communication with the families of the children participating in this activity, we received very good feedback and found that the actual excitement of participation came to the fore in sending their photos into space. For this reason, we kept our promise and sent pictures of all the children and their dreams into space one by one.

The pictures we sent were sent back to earth via the “Es’hail 2/QO-100” satellite, which is also in geosynchronous orbit.


Amateur radio operators, who could communicate directly with the satellite, downloaded images from the satellite with their own equipment. Other amateur radio operators and listeners who did not have sufficient equipment deciphered the pictures on their computers using WebSDR and KG-STV software, which broadcast online on the internet. Then these operators sent us pictures that they decoded (with operator name, callsign, well-wishers…)

As usual, we opened a separate page for each of them based on their efforts, acting faithfully, and uploaded the photos they received to separate galleries there. We then created a list of names for easy accessibility and linked the pages to it. In this way, children will be able to more easily track which countries their pictures have reached.


Pictures of our children were received/decoded by 45 amateur radio stations in 16 countries and 1.119 pictures were sent to us. In terms of its content and image density, it was the most comprehensive activity ever conducted on this satellite in the world.

In this activity, there were very good dialogues and friendships with local and foreign amateur radio operators, and we earned the appreciation of all of them for the activity. On the other hand, we believe that we best promote our country and the strong dreams of our children.

During the operation, we engaged the KG-STV frequency, which was allocated for the use of all world radio amateurs, for about 4 hours each day of the activity. Despite this, amateur radio operators were aware that this activity was for children, the understanding they showed was admirable. So much so that during the sending of images, all operators stopped communicating on this frequency, and even amateur stations sending in a different mode at the close frequency were warned by other amateurs not to interrupt the signal sent.


Some amateur radio operators didn’t just send us the pictures they received. They also shared pictures drawn by their own children via satellite.. This was also a good memory of the activity. When you look at the country names, you will see how amateur radio can amicably bring people together, even if operators are from different countries, religions, languages.


The QO-100 (Es’hail-2) Geostationary SAT 26Est WebSDR system of IS0GRB broadcasting over the web also; automatically retrieved and archived all pictures. On the other hand, the WebSDR manager contributed to us by posting our activity announcement on his page.

Other operators also provided support by providing feedback on the picture and signal quality with each post. Such that; There were people who prepared and shared documents with us even just for this activity. (You will notice that some pictures in the galleries are similar, this is an expression of the inaccurate but edited signals sent in response to the request to be re-sent, and the amateurs’ effort to get all the pictures of the children.)

Another good point is that not only the feedback of radio amateurs, but also the listener (SWL & Listener) operators abroad contributed to our work and shared the pictures they received. Some of them got a picture and some 20 pictures. However, they worked and made an effort to contribute to the children’s activity and shared it with us.

The temporal chronology of the activity is as follows.
