-The [http://en.wikipedia.org/wiki/Low_frequency_radio_range Low Frequency Radio Range ('''LFR''')] is a [[NDB]] that operates at a frequency of 190 to 535 kHz, the [http://en.wikipedia.org/wiki/Long_wave long wave] frequency and a bit above. Across the world there are plenty of LFR stations but it is claimed that LFR is phased out. The long wave frequency is known for it's long range due to sky layer reflections but reflected signals are very unreliable for navigation.
