That portion of the ionosphere existing between approximately 160 and 400 km above the surface of the Earth, consisting of layers of increased free-electron density caused by the ionizing effect of solar radiation. Note 1: The F region reflects normal-incident frequencies at or below the critical frequency (approximately 10 MHz) and partially absorbs waves of higher frequency. Note 2: The F1 layer exists from about 160 to 250 km above the surface of the Earth and only during daylight hours. Though fairly regular in its characteristics, it is not observable everywhere or on all days. The principal reflecting layer during the summer for paths of 2,000 to 3,500 km is the F1 layer. The F1 layer has approxi­mately 5 ´ 105 e/cm3 (free electrons per cubic centi­meter) at noontime and minimum sunspot activity, and increases to roughly 2 ´ 106 e/cm3 during maxi­mum sunspot activity. The density falls off to below 104 e/cm3 at night. Note 3: The F1 layer merges into the F2 layer at night. Note 4: The F2 layer exists from about 250 to 400 km above the surface of the Earth. The F2 layer is the principal reflecting layer for HF communications during both day and night. The horizon-limited distance for one-hop F2 propagation is usually around 4,000 km. The F2 layer has about 106 e/cm3. However, variations are usually large, ir­reg­ular, and particularly pronounced during magnetic storms.

Emergency Locator Transmitter. The ELT is a small radio transmitter that is installed in an aircraft and is designed to being transmitting upon impact (the crash) or it can be manually switched on. The ELT transmits a distincive signal on the international emergency frequencies of 121.5 MHz (VHF) and 243.0 MHz (UHF). This signal is picked up by ground stations, search and resuce aircraft (see Civil Air Patrol and Coast Guard, and satelites. Direction-finding equipment is then used to "home-in" on the signal and locate the downed aircraft.
Click on the recording above to listen to the sound of real ELT radio signal.
