Hi All, An on-line friend recently sent me this timely link re. an upcoming NASA experiment that involves the releasing of an aluminum oxide "cloud" some 60 miles above earth:

(Heaven only knows that the propagation on Topband this season has been far from stellar---"any and all assistance appreciated", Hi). This could be of great benefit to VHF DX'ers, perhaps, if not us denizens of the nether-regions of the frequency spectrum... ~73~ de Eddy VE3CUI - VE3XZ _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw?
