Abstract:

Scratch any older electronics or telecommunications professional and there’s a good chance you’ll find an Amateur Radio operator. Amateur Radio operators of our fathers or grandfathers era typically set-up transmitting stations in sheds down the backyard with wire antennas strung between the trees. Talking to people around the world on HF amateur bands was cool then, as even a phone call interstate was tricky; you needed to book a time with the telephone trunk operator, and it cost a small fortune. The more adventurous amateurs experimented with frequencies above 30MHz, and many pushed the limits of the available technology. In 1947, an Australian amateur (VK5KL) made a two-way contact on 50MHz with an amateur in Hawaii (W7ACS/KH6), a path of 9000 km. That was esoteric stuff - how times have changed!

Abstract:

The article discusses the emergence and development of amateur activities in radio communications and television reception in the USSR. Amateur radio activity in the USSR received legal recognition in 1924. By the end of 1928, more than 450 amateur radio stations were on the air in the country. From the beginning of the 1930s domestic radio amateurs have also mastered the reception of television broadcasts on home-made televisions. By the end of the 1930s. there were a large number of home-made television receivers tuned to the transmission of optical-mechanical television in the country. In this regard, short-line mechanical television broadcasting in the USSR existed until the early 1940s.

Abstract:

During natural disasters, communications can be disrupted, which negatively impacts response time of first responders thus diminishing the level of care provided to disaster victims. In the fall of 2014, as part of a larger community-based participatory research study, the Tarleton Area Amateur Radio Club (TAARC) joined the Department of Nursing, Tarleton State University, and provided amateur radio communications during a disaster preparedness simulation. The simulation was conducted to determine the ability of the university to provide rapid response and render quality, acute healthcare to its neighbors during a natural disaster. The primary goals of the TAARC were to assess the ability to quickly establish radio communications, accurately relay messages, and establish rapport and affiliation between each facility commander and the amateur radio operators. It was determined that communication was key to provide quality care, and the inclusion of amateur radio operators in the simulation helped ensure rapid response times and rapid transport of critical victims.

Abstract:

Amateur talent shows were among the most popular programs on mid-1930s network radio, but for African Americans they had an importance that went beyond entertainment. These shows attracted considerable attention in the black press and from black audiences because they held out the promise of escape from the constraints of Jim Crow into a colour-blind national public sphere. This article explores the participation of African American performers on the most popular of the radio amateur shows, Major Bowes’ Original Amateur Hour. It focusses particularly on two black classical performers on the Amateur Hour – singers Otis Holley and La Julia Rhea – contrasting their success on the radio show with the obstacles they encountered in the segregated world outside the studio. Radio did stimulate hope about the possibility of a race-free sound world, a new sense that such a thing could be possible. That the first generation to test the idea – gifted performers such as Holley and Rhea – often failed to translate radio success into mainstream acceptance, should not lead us to neglect the increase in hope that the early mass media provoked among African Americans.

Abstract:

Purpose The purpose of this paper is to explore the past events where communication challenges have occurred during a disaster, and events in which amateur radio had played a vital role in creating reliable communication links during the disaster response. Furthermore, this paper identifies the modern technology available with amateur radio operators that can be used to create reliable communication networks in order to meet the high demand of disaster communication. Design/methodology/approach In this paper the author has conducted an integrative literature review, while analyzing case studies of disasters where communication challenges have occurred and the amateur radio has provided communication support during a disaster response. Findings In today’s world there is a heavy reliance on centralized communications infrastructure such as cell towers, which are very likely to fail during a disaster. Failure or overload of such infrastructure will cause disruptions in communications and make the disaster response inefficient. Amateur radio does not rely on centralized communications infrastructure, and has the ability to be used to meet the demand during many disaster situations. Thus, it is very important for emergency professionals to understand the value of including amateur radio operators in emergency operations plans. Research limitations/implications Research is qualitative in nature, with an aim to write a short paper introducing the issues of Disaster Communications. Originality/value This paper is intended to provide an insight about the importance of reliable communications during a disaster. Communication interruptions can create a lot of problems and cause inadequate coordination between response agencies. In order to mitigate such challenges it is crucial to study the vital role of amateur radio in supporting the communications when all other mediums of communication fail.

I would like to dedicate this paper to the memory of my husband, Henryk Iwaniszewski, an astronomer working in radio astronomy and electronics, who until his untimely death seven years ago had been very active as president of our local branch of the Polish Amateur Astronomers Association. He was especially keen about introducing astronomy to the general public.I want to speak here mainly, but not exclusively, about the IAU Colloquium No. 98, “Contribution of Amateur Astronomers to Astronomy,” which was held in 1988 in Paris. First of all, some definitions. Thomas Williams of the American Association of Variable Star Observers (AAVSO), from Houston, Texas, introduced at the conference several criteria for identification — first of astronomers, and then of professionals and amateurs.

Abstract The following article describes diagnostic and reliability aspects of amateur radio communications. The intention of precise measuring of quality and accuracy of every contact was present in ham radio from very beginning. The reports were sent and they are still used today, in many variants. In time, the tools to measure ionosphere state and propagation conditions emerged. They are fundamental for communication, especially long distance ones. The article concentrates on description of digital amateur mode, JT9. This mode is very effective, enables worldwide reach and requires simple tools.

Abstract:

In the last couple of years, the use of weak signal propagation reporter (WSPR) has grown significantly in the radio amateur community and beyond. This protocol allows to probe potential propagation paths between radio transceivers, operating at a low-power level. The protocol decodes the received signals and translates them into appropriate signal-to-noise ratio levels, which reveal the possible propagation paths between the transmitter and receiver using ionospheric reflections. In this article, specifically the 160-m radio amateur band is addressed. This band used less intensity for WSPR communication, compared to the other radio amateur bands (80 m and 40 m). Additionally, the 160-m band has specific features such as the link between propagation performance and the Earth’s electron gyro-effect. The aim of this article is to address these features experimentally. First, two identical 160-m band WSPR receiver stations are conditioned to compare the performance of different 160-m band antennas. Each setup, separated by a limited distance, generates almost identical SNR reports, allowing the comparison between the two antennas. Second, a more extended experimental investigation of the propagation path performance on the 160-m band reveals information on the radio wave behaviour between the transmitter and receiver. The first experiment allowed the identification of the most optimal antenna, specifically in the 160-m band. The second experiment shows that the SNR values can vary depending on the polarization shift of the received signal. Possibly, this can be linked to the effect of the magnetic field of the Earth via the electron gyro-frequency.

Abstract:

<p>A critical problem in spectrum sensing is to create a detection algorithm and test statistics. The existing approaches employ the energy level of each channel of interest. However, this feature cannot accurately characterize the actual application of public amateur radio. The transmitted signal is not continuous and may consist only of a carrier frequency without information. This paper proposes a novel energy detection and waveform feature classification (EDWC) algorithm to detect speech signals in public frequency bands based on energy detection and supervised machine learning. The energy level, descriptive statistics, and spectral measurements of radio channels are treated as feature vectors and classifiers to determine whether the signal is speech or noise. The algorithm is validated using actual frequency modulation (FM) broadcasting and public amateur signals. The proposed EDWC algorithm's performance is evaluated in terms of training duration, classification time, and receiver operating characteristic. The simulation and experimental outcomes show that the EDWC can distinguish and classify waveform characteristics for spectrum sensing purposes, particularly for the public amateur use case. The novel technical results can detect and classify public radio frequency signals as voice signals for speech communication or just noise, which is essential and can be applied in security aspects.</p>

Abstract:

A case study is presented which demonstrates the value and validity of a novel approach to the use of consolidated amateur (‘ham’) radio reception reports as indicators of the presence of intense ionospheric sporadic E (Es). It is shown that the use of amateur data can provide an important supplement to other techniques, allowing the detection and tracking of Es where no suitable ionosonde or other measurements are available. The effectiveness of the approach is demonstrated by reference to ionosonde data, and the advantages and limitations of the technique are discussed.

Abstract:

Abstrak: Jaringan tanpa kabel (Nirkabel) atau sering dikenal dengan WI-FI ini berkembang sangat pesat dengan memanfaatkan daya jangkau sinyal yang besar dalam ruangan, ataupun luar ruangan dengan jangkuan yang sangat jauh. Komunikasi radio HF Near Vertical Incident Skywave (NVIS) mampu mengatasi skip zone sehingga tidak mempengaruhi kwalitas pancaran, apakah padang rumput, hutan lebat, lereng gunung dan sebagainnya. NVIS adalah pemantulan satu kali oleh lapisan F/F2 ionosfer, dengan pancaran (sinyal) radio untuk komunikasi HF dengan memancarkan sudut pancaran yang nyaris tegak lurus (Near Vertical) ke atas mendekati 90 º.[1]. MMANA adalah software untuk mensimulasi antenna yang dibuat oleh JE3HHT - Makoto Mori, DL1PBD - Alex Schewelew & DL2KQ – Igor Gontcharenko. Program software MMANA-Antenna Analyzer pertama kali diciptakan oleh Macoto Mori – JE3HHT, seorang amatir radio dari Jepang (10 Januari 1999). Kemudian dikembangkan oleh Alex Schewelew (DL1PBD) dan Igor Gontcharenko (DL2KQ) keduanya amatir radio dari German.[3] Menggunakan software MMANA kita dapat menghitung secara tepat berapa ukuran antenna yang harus kita bangun untuk bekerja pada frekuensi tertentu yang match dan baik. Hasil yang di harapkan dari penelitian ini adalah simulasi perancangan antena radio HF NVIS dapat dipakai untuk komunikasi jarak dekat yag terlewati (Skipzone) dan mmapu digunakan di daerah yang sulit dijangkau sinyal.Kata kunci: Frekuensi 10 MHz, Anlisis aplikasi MMANA, Radio HF NVISAbstract: Wireless network (Wireless), often known as WI-FI, is overgrowing by utilizing a large signal coverage indoors or outdoors with a very far reach. HF Near Vertical Incident Skywave (NVIS) radio communication can overcome the skip zone so that it does not affect the quality of the beam, whether it is grasslands, dense forests, mountain slopes, and so on. NVIS is a one-time reflection by the ionospheric F/F2 layer, with a radio beam (signal) for HF communication by emitting a near vertical beam angle upward approaching 90 º. MMANA is a software for simulating antennas created by JE3HHT - Makoto Mori, DL1PBD - Alex Schewelew & DL2KQ – Igor Gontcharenko. Macoto Mori first started the MMANA-Antenna Analyzer software program – JE3HHT, a radio amateur from Japan (10 January 1999). It was later developed by Alex Schewelew (DL1PBD) and Igor Gontcharenko (DL2KQ), both radio amateurs from Germany. Using MMANA software, we can calculate precisely how much antenna size we have to build to work at a specific frequency that matches and is good. The expected result of this research is a simulation of the design of an HF NVIS radio antenna that can be used for short-range communication that is skipped (Skipzone) and used in areas that are difficult to reach signals.Keywords: Frequency 10 MHz, MMANA application analysis, HF NVIS Radio

Abstract:

Abstract. The Antarctic Treaty, successfully negotiated and signed in 1959, entered into force after ratification by the 12 original signatory countries in 1961. Under the Antarctic Treaty, research activities are now carried out in Antarctica by 54 countries. These are 29 consultative and 25 non-consultative parties. Radio communications have always been an important part of all scientific activities in research stations, ships and aircraft in Antarctica. Historic expeditions in the 19th century and early 20th century had to use wired telegraph stations after returning from expeditions. Between 1911 and 1913, Wilhelm Filchner and Douglas Mawson were the first Antarctic expedition leaders to explore the possibilities of wireless telegraphy. Mawson succeeded in establishing radio communications from Antarctica to Australia for the first time in 1912. Today, the use of communication technologies is almost taken for granted. Direct amateur radio communications via shortwave are a flexible backup and an effective addition to communications about the Antarctic. On the occasion of the 60th anniversary of the Antarctic Treaty, a major international radio activity was launched in the second half of 2021 with which an important contribution to communication to the public was made. Amateur radio is now an important part of research activities in Antarctica.

Abstract:

Appreciation of reliable commuications might seem universal; yet when natural disasters strike, few communities are equipped to handle these essential needs. In many instances their ability to notify the rest of the world about their disaster is seriously impaired. Why this is so and why Amateur Radio Operators, or “hams”, always seem to play such a vital part in community survival is the topic of this article.The best communication systems can fail from traffic overload. As an example, there may be little if any loss of telephone lines or commerical radio links; yet the local population can totally paralyze a system simply by picking up the phone and calling someone. An analogy to this stoppage of communications traffic is seen daily on our expressways as too many cars enter and exceed some critical density at which all traffic must stop.

Abstract:

Abstract. In many countries the electromagnetic field strength in the proximity of licensed amateur radio stations is limited to ensure public safety. If the station antenna(s) and/or the environmental situation are complex, only measurement results are acceptable as proof, and proper calibration of the field strength meters ("radiation monitors") is mandatory. A system and a procedure are described here, enabling calibration of such "radiation monitors" at a high quality level and traceable to the SI units, but with low-budget amateur equipment.

Abstract:

OPTICKS is an art project realized by interdisciplinary artist Daniela de Paulis, in collaboration with the CAMRAS radio amateur association based at the Dwingeloo radio telescope in The Netherlands. The project is presented as a live audio-visual performance during which digital images are transmitted as radio signals to the Moon from a radio station in Brazil, the U.K., Switzerland, Poland or Italy. The signals reflected by the Moon’s surface are received by the Dwingeloo radio telescope, converted back into the original images and projected live at an exhibition venue. The project uses Visual Moonbounce, an application of the Moonbounce technology, developed by the artist in collaboration with the CAMRAS team during her residency at the Dwingeloo radio telescope.

Abstract:

In many situations, the measurement of temperature is done with resistive sensors. This is the case with standard platinum resistance thermometers (SPRTs), industrial level PRTs, resistance temperature detectors (RTDs) and thermistors. There are many possible sources of uncertainty in these measurements. One potential source of error that may be difficult to quantify is the error due to radio frequency (RF) signals. This paper presents data from experimentation done with radio signals close to a temperature measurement location. While the data presented in this paper were not taken in a controlled RF measurement laboratory, they are done in a practical situation. The factors such a type of antenna used, walls between the antenna and measuring sensor, distance between the measuring sensor, and the RF source and length of the temperature sensor leads are disclosed. Different factors are considered such as frequency of the RF signal, power of the RF signal, resistance of the temperature probe and length of the temperature probe leads. Amateur radio equipment is used for the RF signal generation in the high frequency (HF), very high frequency (VHF) and ultra high frequency (UHF) bands. The author uses his knowledge of both amateur radio equipment and temperature metrology to present and analyze the data.
