What Is 8.33 kHz Spacing?
By Reducing the Channel Spacing Between Consecutive Transmit Frequencies in the Aeronautical Vhf Bands, the 8.33 kHz Channel Spacing Adds Two Additional...

Besides, what is frequency spacing?
From Wikipedia, the free encyclopedia. Channel spacing, also known as bandwidth, is a term used in radio frequency planning. It describes the frequency difference between adjacent allocations in a frequency plan.
Similarly, what is 25khz? Narrowbanding refers to public safety and industrial/business land mobile radio systems migrating from 25 kHz efficiency technology to at least 12.5 kHz efficiency technology.
Furthermore, what frequencies do aircraft use?
Common Civilian Frequencies In the US the civil aircraft communications band (118-137 MHz) generally uses 25 kHz spaced channels. As of 2010 aeronautical enroute and flight test stations may use 8.33 kHz spaced channels in the 121.4-123.6, 128.825-132.0 and 136.5-136.875 MHz ranges.
Are aircraft radios VHF or UHF?
1 Answer. The UHF air band operates in AM in a general range of 225.0–399.95 MHz. Many ATC functions have both VHF and UHF frequencies. The bands 235-322 MHz and 335.4-399.9 MHz are also allocated on a primary basis to the mobile-satellite service, limited to military operations.
