30 August 2019, News The strong participation in these events demonstrates the community’s interest in community science and the potential for deployment in science campaigns. This information includes the movements of traveling ionospheric disturbances and other important phenomena at various scales. From a communications point of view, the electromagnetic spectrum is a finite resource. Thus, the amateur community, mobilized on a national scale, can generate a large-scale, novel data set for ionospheric study. 1 March 2021, News Scanning becomes available when the Normandy SR-2 enters the orbit of any planet not involved in a main storyline mission, at which point you'll be prompted to start the scan. Classic rock denotes a music style of rock that came into being in the time period between 1965 and 1975. It sprang from a project by the Ham Radio Science Citizen Investigation (), founded by Nathaniel Frissell, W2NAF, of the University of Scranton, one of the paper’s authors. Radio 2000 is the only facility service radio station in the country and forms part of the SABC's Public Broadcasting Stations portfolio with the intent of strengthening democracy and Nation building through key offerings of sport, music, events of national importance and lifestyle programming. 10 March 2021, News To help you sort by your interests please use our left side navigation. Eos is a source for news and perspectives about Earth and space science, including coverage of new research, analyses of science policy, and scientist-authored descriptions of their ongoing research and commentary on issues affecting the science community. Heathkit IG-1271 signal generator, B&K 512MHz frequency counter, Philips 100MHz scope, Autek WM-1 RF/SWR meter, Heathkit IM-1210 DMM, Ramsey COM3 service monitor, Bird Wattmeter (that I always want more slugs for! These stations supply listeners with standardized time information, high-seas weather forecasts, and other programming. It is the oldest continuously operating radio station in the United States, having been on the air since 1919. We have better knowledge of terrestrial weather because of these networks, but no such system exists yet for ionospheric weather. On 1 October 2019, HamSCI celebrated the centennial of WWV with a Festival of Frequency Measurement. HAARP is the acronym many people recognize, it is an 'ionosphere heater' facility in Alaska. Hams greatly value forecasts of space weather conditions and real-time information about propagation, and the community has a high level of scientific literacy on the topic.

Ham radio is currently experiencing a technical renaissance, thanks to the advent of inexpensive single-board computing platforms (a complete computer built onto a single circuit board, such as a Raspberry Pi) and open-source software. A severe geomagnetic storm (on the order of the Carrington Event of 1859) could have a catastrophic effect on modern infrastructure. https://agu.confex.com/agu/fm19/meetingapp.cgi/Paper/602677, Six New Satellites Watch the Atmosphere over Earth’s Equator, Using Big Data to Measure Environmental Inclusivity in Cities, Superlasers Shed Light on Super-Earth Mantles, An Extremely Elongated Cloud Over Arsia Mons Volcano on Mars: I. Beyond the old-fashioned pursuit of voice communication, the lure of maker movement projects and the removal of the Morse code requirement from the amateur licensing exam have led to a greater number of licensed amateurs than ever before. Through HamSCI, ham radio operators and researchers are bridging this gap by designing hardware for a distributed network of personal space weather stations (PSWSs), accessible to professional and amateur scientists alike. From 1 March 2016, Planet Rock moved from the Digital One DAB multiplex to the Sound Digital DAB multiplex. Kazdan, D., et al. The article “Ham Radio Forms a Planet-Sized Space Weather Sensor Network,” appeared on February 9 in Eos, Earth & Space Science News — an American Geophysical Union (AGU) publication. Every radio, whether it’s a traditional AM/FM radio or a radio found in a smartphone, all uses the same basic method of transmitting information with the help of both a transmitter and a receiver. (2019), A low-cost HamSCI citizen science HF Doppler receiver for measuring ionospheric variability, Abstract SA43C-3213 presented at Fall Meeting 2019, AGU, San Francisco, Calif., 9–13 Dec., https://agu.confex.com/agu/fm19/meetingapp.cgi/Paper/602677.

HamSCI issued an open call to amateur radio operators and shortwave listeners to gather Doppler shift data, and about 50 stations responded (Figure 3). A transmitter, as its name implies, transmits information through the air in the form of a sine wave.
