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.
