Christian Monstein is a native of Switzerland and lives in Freienbach. He obtained Electronics Engineer at Konstanz University, Germany in 1978. Christian is a SARA member and is licensed as amateur radio operator, callsign HB9SCT. He has 20 years of experience designing test systems in the telecommunications industry and is proficient in several programming languages including C++, IDL and PYTHON. He has worked at ETH-Zürich on the design of frequency agile radio spectrometers, FFT-spectrometers, radio receivers and noise calibration transmitters as payload on a drone. He also has participated in the European Space Agency (ESA) space telescope Herschel (HIFI), European Southern Observatory (ESO) project MUSE for the VLT in Chile. Recently, he was involved in the radio astronomy project 'BINGO' in Uruguay / Brazil and in 'HIRAX' in South Africa. He is still responsible (PI) for the hardware and software associated with the e-CALLISTO Project. He is a member of SARA (Society of Amateur Radio Astronomers) as well as a member of USKA (Union of Swiss Shortwave Amateurs) and he was representing Switzerland within Committee on Radio Astronomy Frequencies (CRAF). He is a member of the ISWI steering committee at UN Office for Outer Space Affairs in Vienna (UNOOSA) and has been nominated as a member of ITU. He is also a member of Scientific Committee on Solar-Terrestrial Physics (SCOSTEP) as well as a member of Committee on Space Research (COSPAR).
