You may ask why I made this recording, and it's mainly just for fun because I saw a B movie, Cosmos (2019 film) https://en.wikipedia.org/wiki/Cosmos_(2019_film) , referencing the frequency. Also, due to the reference to the Water hole (radio). "The waterhole, or water hole, is an especially quiet band of the electromagnetic spectrum between 1420 and 1662 megahertz, corresponding to wavelengths of 21 and 18 centimeters, respectively. It is a popular observing frequency used by radio telescopes in radio astronomy" https://en.wikipedia.org/wiki/Water_hole_(radio) . "1420 MHz signal is problematic in itself in that it is "protected spectrum": it is bandwidth in which terrestrial transmitters are forbidden to transmit due to it being reserved for astronomical purposes." AND NO, I did not broadcast on it; I just listened! As part of my Ambient Sounds Project, Martin Brossman Recorded off my Ham Radio using my outside Carolina Windom Antenna on Lower Side Band at 12:38 AM on Oct 18, 2023, for just a little over 1hr. One or two pops were removed caused by me touching the cable during the recording and the gain was raised but not allowed to distort in Audacity. No other sound processing was added. The Squelch was obviously turned up to all thought all sound.

The water hole is sandwiched between emission from neutral hydrogen (1,420 MHz) and emission from molecules of hydroxyl (1,666MHz). Hydrogen atoms emit at 1420 MHz, which has a wavelength of 21 cm. Hydrogen is the most abundant element in the universe. Some believe that extraterrestrial intelligence might favor this frequency to transmit messages. The "Wow!" signal was a strong, narrow-band radio signal in the frequency range of 1420 MHz. It was discovered in 1977 by radio astronomer Jerry Ehman after reviewing recorded data from Ohio State's Big Ear Telescope. The frequency of 1420 MHz is part of a protected spectrum reserved for astronomical research. Terrestrial transmissions are forbidden in this frequency range. " from Google Generative AI.
