There have been a few mails to the reflector mentioning this effect some months ago, and some stations told me I got lost in the LX-effect QRM (IK5ZPV, sri you got my call wrong a few weeks ago...it was DF0WD not DL0WD who was desperately calling you in CW ;-) In short terms, the Luxemburg effect has something to with 'heated electrons' in the ionosphere wich kind of 'transfer' the AM modulation of a strong BC station to other signals. But the way it actually occurs, if it only happens to signals arriving via 'skywave propagation' etc is unknown to me. The only article I found with a tiny bit of information is at http://radon.ece.uiuc.edu/gel_history.html. The search engine showed some hits at www.amrad.org but the amrad server did not respond. Any infos welcome (please to the reflector, it may be interesting for other readers too). Thanks in advance, 73's, Wolf.
