Isn’t ham radio obsolete?
It depends on what you call “obsolete”. Hams use numerous modes including CW (Morse Code), Voice (AM, FM and Single Sideband), Video (analog slow scan and fast scan), and data (RTTY, PSK, MFSK, Spread Spectrum). Morse code has been around since the beginning of radio and still thrives as a nostalgic part of the hobby today. Other Hams experiment with cutting-edge modulation techniques, while others prefer older modes. Many Amateurs build their own equipment from scratch. Internationally, Ham Radio also has several satellites orbiting the Earth. Electronics engineering basics such as antenna design, modulation techniques, amplifier design, filter design, and transmission line theory never really change, and in Amateur Radio you can learn about these and actually see them in action, and not just read about it.
