HAARP is licensed to transmit only in certain segments of this frequency range. When the IRI is transmitting, the bandwidth of the transmitted signal is 100 kHz or less. The IRI can transmit in continuous waves (CW) or in pulses as short as 10 microseconds (µs). See more The High-frequency Active Auroral Research Program (HAARP) is a University of Alaska Fairbanks program which researches the ionosphere - the highest, ionized part of Earth’s atmosphere. The most … See more The HAARP project directs a 3.6 MW signal, in the 2.8–10 MHz region of the HF band, into the ionosphere. The signal may be pulsed or continuous. Effects of the transmission and any recovery period can be examined using associated instrumentation, … See more The main instrument at HAARP is the Ionospheric Research Instrument (IRI). This is a high-power, high-frequency phased array See more In the United States, there have been two related ionospheric heating facilities: the HIPAS, near Fairbanks, Alaska, which was dismantled in 2009, and one at the Arecibo Observatory See more The High-frequency Active Auroral Research Program began in 1990. Ted Stevens, Republican U.S. senator from Alaska, helped win approval for the facility, and construction began in 1993. In early May 2013, HAARP was temporarily shut … See more HAARP's main goal is basic science research in the uppermost portion of the atmosphere, termed the ionosphere. Essentially a transition between the atmosphere and the magnetosphere, the ionosphere is where the atmosphere is thin enough that … See more The project site (62°23′30″N 145°09′03″W / 62.39167°N 145.15083°W ) is north of Gakona, Alaska just west of Wrangell-Saint Elias National Park. … See more WebJan 14, 2013 · As a section, the basses can range up to G above written middle C safely, if the rest of the strings are absent or are in a higher register – but use caution, and ensure …
