North America 10GHz Band Distance Record Broken
New North America 10GHz Distance Record Set
CORONA, Calif. - October 29, 2007 - During the ARRL 10GHz and Up contest during the weekend of
August 18 and 19, 2007, Frank Kelly, WB6CWN operating as 4C2WH in Puerto San Carlos, Mexico (DL34wt)
worked AD6FP in Central California, in Grid Square CM96wa, a distance of 1,460km (907.2mi). This
appears to be a new North America distance record for two-way 10GHz Amateur Radio communication.
In fact, the North America X-Band record was broken five times during the contest weekend:
First by Steve Miller, W6QIW in DM04am at 1,315km, or 817 miles on August 18, at approx. 09:36
A few minutes later, Chip Angle, N6CA and Wayne Yoshida, KH6WZ worked Frank from CM94xm
(1,320km/820 mi.), then CM95qi (1,426km/886 mi.) and again from DM05ax (1,448km/899 mi.)
Finally, on August 19, 2007 at 08:45, Gary Lauterbach, AD6FP, completed a contact with Kelly from
CM96wa, a record-breaking distance of 1460km (907.2mi.).
4C2WH (WB6CWN) was able to copy the N6CA 10GHz beacon, located on Frazier mountain (DM04ms) from
DL34wt at 1,286km - a new DX record for 10GHz beacon DX
Kelly made 53 10GHz contacts from DL34wt on the first weekend. The average contact distance for
all 53 contacts was 1,178km and the accumulated score on just two log pages is over 65,000 points.
Frank Kelly, WB6CWN/4C2WH said, â€œThanks to everyone who supported this effort by roving through
the Grid Squares. This trip would not have been possible without the help and friendship of our
ham-friends in Mexico, especially Bernardo Gonzalez, XE2HWB, president of the Baja Sur Radio Club,
Antonio Garza, XE2HWH, and Dr. Carlos Levy, XE1YK, president of the Federacion Mexicana de Radio
Experimentadores (FMRE), Mexicoâ€™s equivalent of the ARRL in the USA.â€
San Carlos sits at the tip of a western bulge in the Baja Peninsula and has been visited by hams
before, including Jack Henry, N6XQ and Chip Angle, N6CA who reported the reception of both two meter
amateur and commercial FM stations during their visits there back in the mid 90s.
