I earned my Novice license in May 1959 and became KNØUJJ; in September 1959 I upgraded to General, dropping the "N" from my callsign to become KØUJJ. An upgrade to Extra Class came in March 1969, followed in 1977 by a new callsign, KØCF, in the FCC's very first round of "vanity" callsigns. 2018 marks my 59th year of ham radio, and my 49th as an extra-class licensee.

In January 2004, I retired as Director of Bioengineering for the University of Iowa Carver College of Medicine after a 35-year career as an electronics & biomedical design engineer. Medical research equipment that I designed is in use in research labs in 38 countries and 42 of the 50 states. A highlight was designing an instrument package for Spacelab Life Sciences 1, launched aboard Space Shuttle Columbia mission STS-40 in June 1991. My instrument was a human baroreceptor experiment that measured sympathetic peripheral nerve activity following an intentionally induced cardiac arrhythmia. The objective was to learn more about how the human body controls blood pressure. NASA’s video summary of the mission shows an astronaut beginning the experiment protocol.

I am a veteran of the US Air Force (1964-1968) and served with the 5th Fighter-Interceptor Squadron (5 FIS) at Minot AFB, North Dakota. 5th Fighter flew the F-106 Delta Dart, which for some time held the world speed record at 1,525 mph. I was a Nuclear Weapons Specialist, and maintained the AIR-2A “Genie”, a nuclear-tipped air-to-air unguided rocket carried by the F-106.

My operating activities are primarily chasing DX on CW and SSB, with some RTTY as well. I occasionally enjoy doing a CW, SSB or RTTY contest just for fun. Although I make no claim to being a great CW operator, I do enjoy that mode the most.

Awards: DXCC Honor Roll (349 countries total, 336 current), 5-Band DXCC with 30, 17 and 12 meter endorsements, DXCC Challenge (1,600 band-entities), WAZ, WAS, WPX Honor Roll and Geratol #692.

Memberships: IEEE Life Senior Member (Institute of Electrical and Electronics Engineers), ARRL (Diamond Club), Quarter-Century Wireless Association (QCWA #17935), CWops (#1834), the Iowa City Amateur Radio Club (http://www.icarc.org), and I have served two terms as president and am now the webmaster for the Eastern Iowa DX Association (http://www.eidxa.org).

QSL: I try to reply promptly via the same route to all QSLs received, no return postage required (although an SASE is always welcome). I also use ARRL's Logbook of the World (LotW), and upload my log every day that I am active.

Other hobbies: I have had a life-long fascination with astronomy, and I own a Meade LX200 ACF 10-inch computer-controlled Schmidt-Cassegrain telescope. Since retiring, I haven't been able to get engineering out of my system and have a fully-equipped electronics lab in the basement. I like to do a little digital photography (mostly of my grandchildren and "trains, planes and automobiles") using a Canon EOS 60D digital SLR camera with 18-135mm and 70-300mm zoom lenses and a Canon 430EX II external flash. I also do a little woodworking, and have a fairly well-equipped wood shop.
