Continuing on 'biophony'
Continuing from previous item.
Let's take this piece on its own:
The spark created a broad band of frequencies, from near DC up to about 1 Megacycle, with a peak around 500 Kc. All radio stations were sending on this same broad range, with some slight tuning to a couple of narrower subranges. Whenever a ship was using its transmitter to send an SOS, the shore stations that picked it up issued a command via wire telegraph to all broadcasters in the area, and they shut down until the emergency transmission was handled.
This situation couldn't last and didn't last long. Transmitter technology found ways to emit a narrowly tuned sine wave on one frequency, and receiver tech found ways to tune in one chosen freq.
Both changes had to happen at once, and they certainly DIDN'T happen because cosmic rays were striking the transmitters and causing random deterioration. They happened because ORGANIZED HUMAN INTELLIGENCE saw the problem, understood that it was interfering with the PURPOSE of broadcasting for information and entertainment, and SOLVED the problem with specific advances in materials and circuitry and regulations.
LIFE IS PURPOSE.
When life started to emerge in the giant oceans around 600 million years ago, the first organisms to populate this ‘geophony’ still had essentially unlimited bandwidth to choose from. Slowly but surely, however, things became more complicated:We have a nice parallel to this process in the history of radio. In 1920 when voice broadcasting began, most transmitters used an untuned spark. Illustration using an early Signal Corps transmitter:
