HAARP Campaign to Use WSPR on 80 & 40 Meters

Alaska’s super-power High-Frequency Active Auroral Research Program (HAARP) transmitters in Gakona, Alaska, will take advantage of the WSPR digital protocol and the Weak Signal Propagation Reporter Network (WSPRnet) during a short experimental campaign, July 30 through August 1. University of Alaska Fairbanks (UAF) Space Physics Group researcher and HAARP Chief Scientist Chris Fallen, KL3WX, told ARRL that he’ll be conducting research into ionospheric irregularities, but hardly with a weak signal.

“I am conducting a dual-use experiment to create field-aligned — plasma density — irregularities while also modulating the HF beam for a WSPR beacon test,” he said. Specifically, Fallen will be looking at plasma density irregularities in the F-layer of the ionosphere.

Fallen said the WSPR experimental periods are tentatively planned to last about 30 minutes per day and occur between approximately 2300 and 2400 hours UTC on all 3 days, which would put the operations during daylight hours in US time zones. Most transmissions will be at the WSPR 80-meter default frequency of 3.592.6 MHz, Fallen said. HAARP will use full-carrier AM, since it’s not equipped to transmit SSB. The call sign will be WI2XFX. The HAARP transmitters can generate megawatts of RF.
