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. NNNN /EX
