Nice shot, dear Ivan! I have a 8 years old son, Riccardo, that is interested in radio and he learned CW morse code. Now he is able to copy 8 WPM (Words Per Minute) and transmit up to 10 WPM. My best wishes for 11 years old student made his U3S! He is welcome on this forum, if he wants! We are here to create a community interested in small transmitter and balloons launches, but any other idea related to radio signals is welcome! Have a nice day!
