First, it introduces only the fifth member of CQ‘’s DX Hall of Fame, H. Dale Strieter, W4DQS (the DX Hall of Fame was started in 1967 and the first four members were Gus Browning, W4BPD; John Cummings, W2CTN; Dick Spenceley, KV4AA, and Danny Weil, VP2VB) – this year’s inductees are introduced elsewhere in this issue. Among Dale’s accomplishments were participation in the first two DXpeditions to Malpelo Island, which happens to be the geographic topic of this month’s DX column! Plus, some timeless tips on keeping ham radio in the public eye! Enjoy!
