Picture No 4
Yesterday we spoke about Morse code. Morse code is one of the ways that radio amateurs communicate with each other. Morse code is often referred to as CW or Continuous wave. Another method that amateurs communicate with each other is using a microphone. There are three methods of communicating using a microphone and they are;
Single Side Band (SSB) split into either Upper Side Band (USB) or Lower Side Band (LSB)
Frequency Modulation (FM)
Amplitude Modulation (AM)
I’ll describe CW, SSB, FM and AM in more detail in future Blogs.
