You're listening to an audio recording titled "Demo of BPSK31". In this demonstration, the listener is guided through the wonders of the BPSK31, a popular mode of communication among amateur radio enthusiasts, also known as hams. The audio begins with the faint, nostalgic hum of an old radio, setting the stage for what's to come. As you delve further, you will hear a distinct static, a signature characteristic of radio transmissions, which somehow adds to the charm of this old-school communication method. The BPSK31 sound, unique and immediately recognizable to those in the ham radio world, cuts through the static. This is the sound of data being transmitted at a rate of 31 bits per second, hence the name BPSK31. The digital modulation scheme, Phase Shift Keying (PSK), is at the heart of this technology, a detail that comes alive in the audio. Throughout the demo, the listener is given a sense of how hams
