HAARP will be conducting a research campaign from October 19 through 28 (see attachment for exact times and dates)
Amateur Radio Operators are encouraged to provide signal reports.
Unfortunately exact operating frequencies are not known ahead of time due to ionospheric variabilities and the need to consult the ionospheric sounder the day of the experiment to determine best operating frequency.
Attached is the release from the UAF HAARP Program Office.
For any questions, please contact the UAF HAARP Program Office via the contact details provided on the first page of the attachment.
