Welcome to N6NB.com. This site
is about amateur radio. It discusses topics such as VHF/UHF weak
signal operating, roving, contests,
the Quagi antenna design, a
triband cubical quad design,
stations for roving, building a tower trailer
from a kit, measuring antenna gain,
and RF safety. There are also pages about building
the Tehachapi contest station, the
and the problem of ice storms in the mountains.
There are photo albums of several Southern California
Contest Club Field Days, a Field Day-style DX contest
in Mexico, and the 2012 E51YNB/E51TAI operations.
now there's a page describing the 2011 fire that
destroyed the Tehachapi contest station. This website is an ongoing
project. Most recent revisions: 1/13/2023.
Recently added or revised: 60 years of VHF adventures,
page, RF safety page,
Contest rules and results, setting microwave
world records (now including a link to
a narrated PowerPoint show with videos), small senior rovers, and August
UHF Contest results.
A personal note: I've been involved
in many aspects of amateur radio over the 65 years I've been
It's been fun. I did some of the earliest portable e.m.e.
work--in places ranging from Alaska to the Utah-Nevada border.
on I found out I liked radio contests and also building things for the
VHF, UHF and microwave bands. In the 1960s I discovered that
made it easier to win the VHF/UHF contests that are sponsored four
a year by ARRL, the national association for amateur radio. By
I had finished #1 nationally in the single operator category of 12 VHF
or UHF contests--all while operating in a parked van or camper on
mountaintops from coast to coast. That resulted in several
records that were never broken under the section multiplier
system. (In the 1980s latitude and longitude-based grid squares
ARRL sections as multipliers and then more categories were added,
the rover, high power, low power and QRP categories). Under the
system I won another 26 contests nationally as a rover and seven in the
QRP portable category, setting scoring records for the January, June
September VHF contests and the August UHF contest. I've now won
at least an ARRL division leader certificate in a VHF contest in SEVEN
decades: the 1960s, 1970s, 1980s, 1990s, 2000s, 2010s and now the
2020s, with at least one #1 score nationally in six of those
The Tehachapi Mountain antenna farm (shown
above) was the realization of a longtime dream: to have a good non-portable
station on a mountaintop. Building the buildings and putting up the
towers was a lot of work, but when the weather was bad it was a luxury
to operate inside a building on a good mountaintop, not in a car (until
the fire, see above).
Portable VHF contesting prompted me to look for
better and simpler antennas. With the help of Will Anderson, AA6DD,
I designed the Quagi antenna on a backyard antenna range in 1972.
That led to the ARRL Technical Excellence Award in 1977 and helped me win
the Radio Amateur of the Year award at Dayton in 1980. I also received
the John Chambers Memorial Award of the Central States VHF Society in 1978
and again 37 years later in 2015.
I served four terms as an elected ARRL vice director
in the 1980s and early 1990s and was chairman of the ARRL Contest Advisory
Committee during the 1970s. I've also done some writing about amateur
radio, including a number of articles for QST, CQ and Ham
Radio magazines. I co-authored a book about amateur radio with
Jim Steffen, KC6A, Computer Programs for Amateur Radio (Hayden
Book Co., 1984). I also wrote several college textbooks, including
20 editions of Major Principles of Media Law, and was a university
professor for 37 years, mostly at California State University, Fullerton.
I hold Ph.D. and J.D. degrees and have been a member of the California
Bar since 1975 (now retired/inactive).
