 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 local time.

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, Thanks 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), Mexico's equivalent of the ARRL in the USA.

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.

1996 - 2024


Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
