I just finished reading an article in the February issue of QST (pages 37-40) on the subject of Radio Waive Propagation. The author is none other than Kazimierz Siwiak, AKA Kai, KE4PT, our Club's secretary. Read it and log on www.arrl.org/cover-plaque-poll and cast your vote for the best article of this month. 73, Dave, W4DN
