About CT7AKG
I am Diogo Saraiva, licensed amateur radio operator in Portugal with callsign CT7AKG. My passion for amateur radio began some years ago and since then I have explored various aspects of this fascinating activity that combines technology, communication and experimentation.
As a Computer Engineering student, I find in amateur radio the perfect bridge between the digital and analog world — from radio programming and station automation, to antenna building and DIY projects with Arduino and RF.

💭 What Amateur Radio Means to Me
Amateur radio is much more than just communicating via radio — it's an activity that unites science, technology, experimentation and community. Each contact is unique, every DIY project is a learning opportunity, and each license upgrade is a milestone of progress.
I find in amateur radio the perfect combination between my studies in Computer Engineering and my passion for electronics and RF. Whether programming microcontrollers for antenna analyzers, or making an SSB QSO with an operator on the other side of the world, this activity keeps me constantly learning and experimenting.
