UHF channel 37 refers to a specific frequency on the Ultra High Frequency (UHF) band of the electromagnetic spectrum. It is typically used for television broadcasting and falls between 608 and 614 MHz.
The main reason for the absence of UHF channel 37 is to avoid interference with radio astronomy observations. This frequency range is reserved for scientific research and is protected by international agreements.
The use of UHF channel 37 for television broadcasting can cause interference with radio telescopes and other instruments used for astronomy. This interference can disrupt data collection and hinder scientific research.
In addition to protecting radio astronomy, UHF channel 37 is also used for medical and scientific equipment, such as MRI machines and wireless medical telemetry devices. Allowing television broadcasting on this frequency could also cause interference with these important technologies.
One solution that has been proposed is to move television broadcasting to a different frequency range, such as the UHF band from 470 to 698 MHz. However, this would require significant changes to broadcasting equipment and infrastructure, making it a challenging and costly solution.
