Thanks for the post Geoff! I ran across the announcement a few minutes before they started yesterday. Listening with K3 S/N 00010 I heard the echoes on 6.7925. I'd have called the echo a typical trans-polar long-path signal but terrestrial signals aren't delayed several seconds!
Interestingly, I could not hear any echo on 7.4075 when they QSY'd, even though it was immediately after hearing them on 6.7925 MHz. I'll try to record the signal tonight to send them with my reports.

Sorry for using bandwidth. I thought that the following message received from the ARRL was worth posting in case somebody who might be interested has not seen it. I should have posted it yesterday. 73, Geoff GM4ESD * 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 19-20. 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 0500-0600 UTC, and on 7.4075 MHz from 0600-0700 UTC. On January 20, listen on 6.7925 MHz from 0630-0730 UTC, and on 7.4075 MHz from 0730-0830 UTC (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, it will be necessary to use USB or LSB mode on the receiver 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 <[EMAIL PROTECTED]>, and list your call sign and the type and location of your receiving equipment and antennas. -- Information provided by Ed Kennedy, K3NS, HAARP Navy Program Manager * Crawlie F: _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
