ARLX002 Lunar Echo Experiment looking for Amateur Radio Participants

The HF Active Auroral Research Program (HAARP) in Alaska and the
Long Wavelength Array (LWA) in New Mexico are planning an
additional lunar echo experiment for January 18-19.

Interested radio amateurs are invited to participate in this
experiment by listening for the lunar echoes and submitting
reports.

On January 19, listen on 6.7925 MHz from 0500-0600z, and on
7.4075 MHz from 0600-0700z.  On January 20, listen on 6.7925 MHz
from 0630-0730z and on 7.4075 MHz from 0730-0830z (depending on
frequency occupancy at the time of operation, it may be
necessary to adjust the frequency slightly).

Based on previous experiments, investigators believe it should
be possible to hear the lunar echoes with a standard
communications receiver and a simple 40 meter dipole antenna.
The format for the transmissions will follow a five second cycle
beginning on the hour and repeating continuously.

The HAARP transmitter will transmit for the first two seconds.
The next three seconds will be quiet to listen for the lunar
echo.  Then HAARP will transmit again for two seconds, repeating
the cycle for one hour.  In the second hour, this five second
repetitive cycle will be repeated at a different frequency.  All
transmissions from HAARP will be CW (no modulation).

Depending on ionospheric conditions, it may or may not be
possible to hear the HAARP transmission directly via skywave
propagation.  Since HAARP will not be using any modulation, set
your receiver on to CW mode to hear HAARP and the lunar echo.
Investigators are interested in receiving signal reports from
radio amateurs who may be able to detect -- or not detect-- the
lunar echo or the transmitted skywave pulse from HAARP.

Submit reports via e-mail to mbreport at haarp.alaska.edu and list
your call sign and the type and location of your receiving
equipment and antennas.
