Hermann Schumacher, born in Siegen, Northrhine-Westphalia, in 1957, was infected early by the wireless virus. After several years as a short wave listener (SWL), he obtained his first amateur radio license with the call sign DC3DL in 1973, initially with privileges restricted to 144 MHz and higher frequencies. In 1976, Hermann upgraded to a license class with full privileges, and obtained his current call sign, DF2DR.
The same year, he started his studies of electrical engineering at RWTH Aachen, where he graduated with the Diplom-Ingenieur degree in 1982, only to stay on for doctoral studies at the Institute of Semiconductor Technology under Heinz Beneking (himself a former radio ham). Between 1982 and 1986, amateur radio activities were a bit on back burner since Hermann was too busy with his job, with the German Red Cross in Aachen, and most importantly with his growing family.
Hermann obtained his Doctorate in Engineering (Dr.-Ing.) with distinction in 1986. Immediately afterward, he, his wife Christiane (call sign DG3DY) and their two sons moved to Red Bank, NJ, where Hermann worked for Bell Communications Research as a member of technical staff. From his home, he was active as W2/DF2DR, mostly in Packet Radio on 144 MHz, but also on 7 MHz. Hermann and Christiane were members of the Ocean-Monmouth Amateur Radio Club (OMARC). Most of Hermann’s spare time was devoted, however, to his work as an emergency medical technician with the Red Bank First Aid and Rescue Squad, where he responded to more than 1,000 emergencies over the years.
In 1990, Hermann accepted a professorship at Ulm University, and so the family moved back to Germany (which had not originally been the plan). Here, he is currently the director of the Institute of Electron Devices and Circuits and the School of Advanced Professional Studies, the university’s continuing education arm. From 1997 through 2014, he led the international Master program in Communications Technology, when of the earliest engineering programs in Germany taught exclusively in English.
In Ulm, Hermann has also been active in emergency medical services. He is a certified mountain rescue technician, occasionally active with emergency medial services for the German Red Cross, and initiated a group of radio amateurs supporting the German Red Cross with technical and operational expertise.
In ham radio, Hermann enjoys operating on HF, often in telegraphy and with low power, but is also the sysop for the local D-STAR repeater DB0ULM. He can be heard activating Summits on the Air, predominantly in telegraphy on 7 MHz, but also from home in SSB, on 28 MHz when the band is open. Hermann also enjoys experimenting with different digital modes on HF, for text and voice communications. He is a member of the DARC, local chapter P14 (Ulm).
