ITU RR table: 8.3-110 kHz

8.3 – 110 kHz

Spanning the Very Low Frequency (VLF) and lower Low Frequency (LF) ranges, this band is notable for its exceptional propagation — VLF waves penetrate seawater tens of metres deep, enabling submarine communications. Key allocations include maritime radionavigation (LORAN, now largely decommissioned), precision time-signal stations (DCF77 at 77.5 kHz, JJY at 40/60 kHz, MSF at 60 kHz), and meteorological aids.
