RESEARCHERS FIND WAY TO 'MAP' SPORADIC-E

JIM/ANCHOR: We all know sporadic-E is unpredictable - or is it? 
Researchers in New Mexico say: "Not so fast." Geri Goodrich, KF5KRN, 
explains.

GERI: Making use of broadband radio noise and unintentional RF 
emissions from power lines, researchers in New Mexico report that 
they are now able to characterize and map sporadic-E, the erratic 
phenomenon that we hams make use of for long-range communications 
mainly on 10 and 6 meters. Until now, sporadic-E's occurrence has 
been largely unpredictable.

Researchers at the Air Force Research Laboratory at Kirtland Air 
Force Base made use of a method developed by a team headed by 
research physicist Ken Obenberger, who said the technique can be 
employed anywhere there is an electrical grid.

Chris Fallen, KL3WX, one of the research collaborators at the lab, 
was quoted in its publication comparing the technique to weather 
forecasting. He says: [quote] “This is similar to how meteorologists 
can predict how likely thunderstorms will occur in the afternoons 
above New Mexico during monsoon season, but use Doppler radar to 
identify and track specific thunderstorms as they occur. Ken’s 
technique basically provides weather radar for sporadic-E, only using 
radio noise from power lines as the radar transmitter.”  [endquote]

The publication noted that the ability to more accurately get a 
handle on sporadic-E would be vital during disasters that call upon 
amateur radio operators to relay emergency information.

KICKER: 2019 YHOTY DHRUV REBBA KC9ZJX GETS ARRL POST

JIM/ANCHOR: Finally, Newsline takes special joy in announcing that 
Dhruv Rebba, KC9ZJX, our 2019 Bill Pasternak WA6ITF Young Ham of the 
Year, has been appointed the ARRL Illinois State Section Youth 
Coordinator. The prominent post is the latest accomplishment the high 
school student has achieved. Last December, Dhruv was one of two 
students chosen to receive the "I Have a Dream Award" for Youth at 
the 44th annual Martin Luther King Awards Luncheon. In 2018, he was 
part of the Dave Kalter Youth DX Adventure in Curacao. In his role 
with the ARRL, Dhruv is responsible for promoting on-air activities 
for youth, including School Club Roundup, and encouraging other 
youth-related programs and ideas. Dhruv has been a ham since the age 
of 9. All the best, Dhruv, we couldn't be prouder of you!
