FM broadcasting
VHF Radio waves do not travel far beyond the visual horizon, so reception distances for FM stations are usually limited to 30–40 miles (50–65 km) They can also be blocked by hills or buildings.
Radio Caroline
Radio Caroline announced a wavelength of 199 metres, rhyming with the name, but was actually broadcasting on 197.3 metres (1520 kHz). Stations in the UK announced the wavelength in metres, and radios at that time were tuned using an analogue dial. The absence of precise digital readouts allowed for some leeway between the precise transmission frequency and the channel announced on the air. The Dutch offshore station Radio Veronica was on 192 metres (1562 kHz) and Radio Atlanta broadcast on 201 (1493 kHz).
