The search for extra-terrestrial intelligence (SETI) using Radio Telescopes
Abstract:
With the birth of radio astronomy, scientists inspired by the idea of technologically capable life beyond Earth hoped a radio telescope might be able to pick up an alien radio signal. Looking for these signals, however, has proven to be a harder task than the pioneers of SETI hoped for: 6 decades later we have only negative results. The parameter space for how and where to look is multidimensional and reducing it calls for educated assumptions, which are often constrained by the capabilities of our instruments. Additionally, we live in an increasingly radio-contaminated environment and picking up such a beacon is as big of a challenge as properly identifying it. How do we filter radio frequency interference? What do we choose to look for? And how can we leverage the features of groundbreaking radio telescopes and novel techniques to aid in the search for intelligent life?
Brian Coleman – UK Meteor Radio Beacon Project Lead
In addition to a fascination with astronomy Brian obtained his first amateur radio licence in 1967. Always interested in the technical challenges of designing and building radio equipment particularly for the higher frequency bands, VHF, UHF and Microwave this led to the challenge of Earth – Moon – Earth communications ( EME ) where the moon is used as a reflector to extend range beyond the horizon for frequencies not refracted or reflected by the ionosphere. After a career in the electronics industry the two interests, Radio and Astronomy inevitably came together. After completing the Introduction to Radio Astronomy course run by the University of Manchester Brian used his 3.7m EME antenna to study the radiation from Neutral Hydrogen in our Galaxy. The Hydrogen Line Observing Group was established giving its members the opportunity to make their own observations controlling Brian’s telescope remotely. Recently, with support from the RSGB and the BAA Brian has led a group of volunteers who are building a bi-static radar system to study meteors entering the earth’s atmosphere over the UK
The UK Meteor Radar Project has been established and run by a group of skilled volunteers from the amateur radio and radio astronomy fields. These volunteers bring the specialist skills required to design, build and run both the radio beacon and the receiver network.
The aim of the project is to provide an extensive and capable resource to the science and STEM communities to enable the study of meteors over the UK, although coverage further afield is possible but not currently covered by the receiver network.
This is an extensive project that has only been made possible by the generosity of both the dedicated design team and a number of external organisations. This resource is planned to be provided without charge to all those who wish to use it and hence the donation of time, funds and equipment has been essential to realise this ambition. We would like to thank those who have already supported us and would of course welcome any addition support.

How to Catch a Pulsar
The strongest pulsar in the northern hemisphere is B0329+54. The main pulsar characteristics are very accurate pulse timing and broadband noise transmission; the energy scintillates and is dispersed in frequency. Pulsars are one of the weakest radio sources but their published characteristics are freely available to aid amateur search. Pulse period-matched integration is the most effective technique to recover a pulsar from galactic and receiver noise plus possibly some minor local interference. There is good availability of hardware to construct a backyard radio telescope and free software to collect and process the data. There is still scope for amateurs to further process the data to better confirm detection; a technique investigated here, exploits the random scintillation property to improve signal confidence.
Hermann Fenger-Vegeler
Born in 1954 and raised in Duesseldorf, Germany, he studied physics at Bielefeld University from 1975 onwards. After graduating with a degree in physics, he joined the emerging software industry, working in the warehouse control systems sector until his retirement in 2021. From a young age, he was passionate about astronomy and spaceflights and remained committed to astronomy throughout his working life, conducting studies in the field of asteroids, variable stars, and comets. Only later, and actively since EUCARA 2018, did he turn to radio astronomy. Fortunately, he was able to start as a guest at Per Dudek’s station in Kiel, conducting HI measurements at 1420 MHz and pulsar observations at 1310 MHz with the 9 m dish. His work, which he will report on at EUCARA 2025, was also kindly supported by Per Dudek and his team. It is a huge challenge to get involved in this topic as an amateur and so his motto is a variation of what started it all for him : ‘It’s a small step for menkind but a giant leap for me !’

Abstract
The Kiel-Roenne amateur radio station has been known for some time, particularly for the EME – beacon in the 10 and 24 GHz range. This versatile facility is also used as a ground station for NASA in cooperation with the University of Kiel. Satellite observations and radio astronomy have been carried out there for more than 20 years. Initially, HI observations were done but pulsar observations at 1310 MHz were later added. After an interruption at the end of 2016, these observations resumed in 2021, this time with purely digital signal processing and evaluation. After some initial difficulties, pulsars have been received again since mid-2023. The results of these measurements and a system overview will be presented here. The ongoing long-term observation of PSR-B0329+54 will also be reported. This includes motivation, first results, and further planning.

Water maser observations at 22 GHz
Water is one of the molecules which can form natural masers in a astrophysical environment. Masers can be found in regions with intense infrared radiation such as star forming regions or around giant stars. Water masers are particularly interesting as they can be very variable and sometimes exhibit very strong flares.
The talk will report on the observations conducted in since 2024 (and some earlier observations) with the 10-m dish at Astropeiler Stockert. The instrumentation used will be explained covering the frontend design and the SDR backends. The spectra recorded cover W3, W49, W51, Centaurus A, Cygnus X and Orion KL with focus on the variability.

Abstract
Radar and the Birth of Radio Astronomy This talk will look at the origins of Radio Astronomy, focusing on the development of Radar in the 1930s, the use of Radar in WWII and the subsequent discovery of “cosmic noise” which opened up the electromagnetic spectrum to Astronomers in a way unprecedented since Galileo and the telescope. It will include discussion of key events of WWII including the Battle of Britain, the Tizard Mission and the Bruneval Raid – and how captured German and Japanese Radars became the first Radiotelecopes. It will examine how wartime Radar personnel at TRE in the UK and CSIRO Radiophysics in Australia “accidentally” became the first Radio Astronomers – people such as Bernard Lovell (Manchester), Martin Ryle (Cambridge) and Joe Pawsey (Sydney). It will describe the growth of Radio Astronomy up to the 1960s in the context of key discoveries including quasars, pulsars and Cosmic Microwave Background – discoveries which transformed our knowledge of the universe and gave evidence for the Big Bang and the existence of Black Holes. The aim of the talk is to put Radio Astronomy into an historical context as part of the evolution of “big science” in the second half of the Twentieth Century and examine how conflict between the key Radio Astronomy groups in the 1950s led to the growth of a major new branch of Astronomy. The talk will finish with a brief look on the future of Radio Astronomy through multinational projects such as the SKA and Event Horizon Telescope.

Thomas Telkamp is an active volunteer at the historic Dwingeloo Radio Telescope in the Netherlands. There, he contributes to various radio astronomy and deep space communication projects. Recent highlights include the measurement of several Radio Recombination Lines, the reception of Voyager 1, and receiving an echo from Venus. All software developed and data collected in these projects is openly available to the public. Thomas is also co-founder of Lacuna Space, a new-space company pioneering global Internet of Things (IoT) connectivity via satellite. Headquartered at the Harwell Campus in Oxfordshire, Lacuna Space aims to enable IoT access anywhere on Earth. After serving as Chief Technology Officer for several years, Thomas now leads the company’s research and development efforts, with a focus on advanced RF modulation techniques and on-board signal processing.
Abstract:
Restored in 2012 with the help of radio amateurs, the Dwingeloo Radio Telescope not only regained its ability to receive signals from space but also acquired transmit capability. This new functionality is frequently used by amateur radio operators for moonbounce communication (Earth-Moon-Earth, or EME). It also enables active radar observations of nearby celestial bodies by reflecting radio waves off their surfaces, opening the door to experiments in planetary radar astronomy.
In this presentation, we will discuss ongoing radar experiments targeting the Moon and Venus, detailing the technical setup, signal characteristics, and processing techniques such as Delay-Doppler mapping. We will also share results from bi-static lunar radar experiments, carried out in collaboration between Dwingeloo and the Astropeiler Stockert radio telescope in Germany.
Dr Andrew Thornett
3D and 4D mapping of the Milky Way, using data from Lichfield Radio Observatory (LRO), central UK, collected by two radio telescopes, an ex-military dipole array and a parabolic solar cooker.
Measuring hydrogen line (1420.405MHz) in the Milky Way is a common project for amateur radio astronomers. Such measurements can be used to map the galactic arms of the Milky Way, measure our galaxy’s mass, and demonstrate the presence of dark matter in the galaxy.
Methods of displaying the data obtained from such projects has been limited to graphical plots of data and 2 dimensional maps of the galaxy. These are often difficult for members of the general public to properly appreciate, which makes their use in outreach of limited value.
There are now new ways of presenting our findings which can provide greater appeal to those who are not well versed in radio astronomy methods and interpretations.
This talk explores these new methods, including displaying the data in three spatial dimensions, using free software packages such as Easy Radio Astronomy Software and Rinearn 3D. In addition, these programmes can be used to map the data to a sphere in order to give views of the Milky Way as it would be seen from the surface of the Earth or from outside a ball surrounding the Earth.
The methods are used to display data collected at Lichfield Radio Observatory (LRO) in central United Kingdom, from its three hydrogen line radio telescopes, LRO-H1, based on an ex-military dipole array 86cm x 86cm in size, LRO-H2, built around an 150cm diameter parabolic reflector originally designed to act as a solar cooker, and LRO-H3, which uses as its aerial a 13-element Patch Yagi.

Workshop Title: Exploring the NanoVNA – A Beginner’s Guide to Optimising Radio Telescopes.
Andrew Thornett and Jason Burnfield.
Abstract:
This one-hour introductory workshop is designed for amateur astronomers interested in practically using the NanoVNA (Vector Network Analyzer) to analyse and enhance radio telescope systems, but who find it difficult to understand all the theory and electronics. Participants will learn how to use this powerful, affordable tool to measure antenna impedance, match feedlines, diagnose signal path losses, and optimize overall system performance at radio astronomy frequencies, including the hydrogen line at 1420 MHz. The session will include a practical demonstration, including a guide to making a shortened antenna far-field, testing range, guidance on interpreting key plots (such as S11 and Smith charts), and tips for real-world use in low-noise observational setups. No prior experience with VNAs is required—just a passion for refining your radio astronomy equipment.
