Adventures in ham radio

About WW7D

I am Darryl Holman, WW7D. You can reach me at djholman at uw dot edu. This blog is about my adventures in ham radio. Thanks for stopping by.

I was first licensed as WN9TCY in Feb. 1976, and the world was mine with a crystal controlled Globe Scout Deluxe transmitter, a Hammarlund receiver of some type, and a dipole. I was 15 years old and living in suburban Madison, Wisconsin.

It took me seven months to upgrade to the General license, and I became WB9TCY. Within a year I upgraded to an Advanced licensed that I held until upgrading to the Extra in December 2010. Along with that upgrade came the callsign WW7D.

Two breakthroughs in my early career were a Swan 350 (that I still own today) purchased used in Aug. 1977 and a quad antenna rebuilt from donated carcases that had succumbed to a nasty ice storm. I had also acquired a dilapidated 30 foot crank-up tower and a rotor of some type.

Late in 1978 the log entries became more sporadic as girls, cars, motorcycles, and computers competed for my time. I headed off to college in the fall of 1979, and my logs show long periods of inactivity punctuated by bursts of log entries here and there. In 1999 I moved to the Seattle area to take a faculty position at the University of Washington, and it wasn’t until 2010 that I finally had time to think about hamming again.

My primary interests are DXing, contests, antenna building, mobile contesting and CW. I’ve recently taken up roving by car and airplane during VHF and UHF contests. After 30 some years, I have finally figured out how to use my Vibroplex bug (it starts with careful adjustment).

My main HF rigs are a Kenwood TS-480 and a Yaesu FT-857D. Home antennas include a home-built broadband hex beam for 20 through 10 meters, a multi-band dipole for 40 through 10 meters, an 80 meter delta loop, and an old 5 band Hygain vertical covering 80 through 10 meters. I use a couple of homebuilt screwdriver antennas for mobile and portable HF contesting.

For VHF+, the TS-480 is used on 6 meters and the FT-857D is used for 2 meters and 432 MHz. I put together an Elecraft XV222 transverter as an all-mode compliment to a Jetstream JT220M FM 222 MHz rig. For 902 MHz, I have an SSB Electronic LT33S 902 MHz transverter and Stealth Microwave 50W amp, as well as a Kenwood TK-981 for 927.5 MHz FM. And for 1296 MHz, I recently bought an SG Lab transverter that drives an old Down East Microwave 18W amplifier, and I use an Alinco DJ-G7 for FM. I use a variety of homebuilt VHF and UHF antennas.
