One member of the Southeast Ohio Radio Adventure Team succeeded in activating Dayton Aviation Heritage National Historical Park and North Country National Scenic Trail as part of the ARRL's year-long National Parks on the Air (link). Eric McFadden, WD8RIF, activated Dayton Aviation Heritage National Historical Park, HP11 (link) and the North Country National Scenic Trail, TR04 (link) at the Huffman Prairie Flying Field Interpretive Center.
Upon arriving at the Interpretive Center, Eric stamped his Passport 2016 and spoke with the ranger who readily gave Eric permission to perform the operation at the park gate at the intersection of the park and the North Country National Scenic Trail.
As at previous activations, Eric's station consisted of his Enhanced KX3 Travel Kit, his MFJ-1910 33' fiberglass telescoping mast, and a custom clipboard.
Because it was CQ World Wide CW weekend, Eric started operations on 30m but QSOs came very slowly. His first QSO came at 1931 UTC with WK2S after some twelve minutes of calling "CW". Eric made two more QSOs on 30m, with the final one coming at 1933 UTC with W1VT. Eric switched to 40m and called "CQ" for about ten minutes before making his first QSO on 40m at 1942 with NJ3K. QSOs on 40m came so slowly that Eric became concerned he wouldn't make his required ten QSOs. Fortunately, the band suddenly opened at about 2007 UTC and Eric's 12th QSO came at 2010 UTC with NV4G. It appears the bands had been wiped out by a short-duration radio blackout. All QSOs were made at the 5-watt level.
Eric recorded at temperature of 49°F at his key during this operation.
