From URL: http://www.haarp.alaska.edu/haarp/haarpFactSheet.html Since the sun's radiation creates and maintains the ionosphere, sudden variations in this radiation such as those caused by solar flares can affect the performance of radio systems. Sometimes these natural changes are sufficient to induce large transient currents in electric power transmission grids, causing widespread power outages. Lightning is known to cause substantial heating and ionization density enhancement in the lower ionosphere, and there are indications that ground-based HF transmitters, including radars and strong radio stations, also modify the ionosphere and influence the performance of systems whose radio paths traverse the modified region. Perhaps the most famous example of the latter is the "Luxembourg" effect, first observed in 1933. In this case a weak Swiss radio station appeared to be modulated with signals from the powerful Luxembourg station, which was transmitting at a completely different frequency. Music from the Luxembourg station was picked up at the frequency of the Swiss station. -- The Anon Keyboard I doubt, therefore I might be "dxAce" wrote in message ...

I've read that LDEs were first observed during the ionospheric reasearch of the 1920s. Any help on this question would be enormously appreciated. Very long delayed echos, on the order of a few minutes, have also been claimed. One theory has it that there's an alien repeater in lunar synchronous orbit. Frank Dresser |

I heard my own signals returned as a LDE sometime in the50's shortly after I was licenced. I was on 20m late at night and sent out a standard 3x3 CQ. When I went to receive I heard the last part of my CQ coming back with a very ghostly tone "....CQ de GW3IJE GW3IJE GW3IJE AR K". Just like aurora which I didn't hear until many years later.

I rememmber Art Bell a few weeks ago had recordings of the LDE and the
HAM radio signals which he played on the air.. even mixing in with the bumper music :P "M. J. Powell" wrote in message ...

Art did? Did you catch any callsigns ? It may have been my recording. He asked me to forward them to him about a month ago or more.
