Successful HAARP WSPR research campaign

The ARRL report HAARP’s WSPR research campaign has yielded hundreds of
reports of reception on the 40 and 80 meter amateur radio bands

The ARRL story says:

Just-completed research at the High-Frequency Active Auroral Research
Program (HAARP) transmitters in Gakona, Alaska, successfully took advantage
of the WSPR digital protocol and the Weak Signal Propagation Reporter
Network (WSPRnet) on July 30 through August 1.

University of Alaska Fairbanks (UAF) Space Physics Group researcher and
HAARP Chief Scientist *Chris Fallen, KL3WX*, told ARRL that the research —
HAARP’s fourth research campaign under management of the University of
Alaska Fairbanks — went well.

“My ‘citizen science’ experiments were funded by the National Science
Foundation and were conducted for approximately 30 minutes at the end of
each campaign day,� Fallen told ARRL. “They consisted of 2-minute
transmissions using the WSPR digital mode in the 40- and 80-meter bands,
with a 2-minute off period between transmissions.�

He said HAARP transmitted in full-carrier, double-sideband AM because it
does not have SSB capability. HAARP operated under its Part 5 Experimental
license, WI2XFX, with Special Temporary Authority (STA) from the FCC to
transmit on amateur bands.

“I systematically varied the HAARP transmission parameters, such as gain,
net power, beam direction, and polarization, to see how they affected the
reception reports collected in the WSPRnet.org database,� Fallen said.
“During the 3 days, we gathered more than 300 confirmed reports of signal
strength and location from nearly 100 unique participants throughout Canada
and the US.�
