VLF Frequency List

Very Low Frequency (VLF) refers to the frequency band from 3 kHz to 30 kHz.

Here is a list of notable VLF frequencies and their common uses:

VLF Frequencies and Uses

  1. 8.27 kHz: Submarine communications (naval).
  2. 9.00 kHz: Standard frequency and time signal transmission.
  3. 16.4 kHz: SAQ transmitter in Grimeton, Sweden, for maritime navigation and communication.
  4. 18.1 kHz: Submarine communications (naval).
  5. 19.6 kHz: Submarine communications (naval).
  6. 21.4 kHz: Submarine communications (naval).
  7. 22.2 kHz: Submarine communications (naval).
  8. 24.0 kHz: Submarine communications (naval).
  9. 25.2 kHz: Submarine communications (naval).
  10. 26.1 kHz: Submarine communications (naval).
  11. 27.0 kHz: Submarine communications (naval).
  12. 28.5 kHz: Submarine communications (naval).

Key Points

  • Time Signal Stations: VLF is used for transmitting accurate time signals for synchronization purposes.
  • Submarine Communications: Due to its ability to penetrate seawater to some depth, VLF is widely used for communication with submarines.
  • Maritime Navigation: Certain VLF frequencies are used for maritime navigation signals.
