One member of the Southeast Ohio Radio Adventure Team succeeded in activating Hopewell Culture National Historical Park as part of the ARRL's year-long National Parks on the Air (link). Eric McFadden, WD8RIF, peformed a solo activation of Hopewell Culture National Historical Park, HP15 (link) at the Mound City Group in Chillicothe, Ohio.
Upon arrival at the Visitor Center, Eric stamped his Passport 2016 and spoke with the ranger who readily gave Eric permission to operate.
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 of the cool temperature, Eric chose to operate inside the car and he chose to power the transceiver using the car's power socket instead of his 5aH gel-cell. Eric was on the air at 1446 UTC.
Eric began operations on 20m but could raise no responses to his call of "CQ". He switched to 40m and his first QSO there came at 1457 UTC with K2ZF. QSOs came slowly but steadily on 40m with Eric's 11th and final QSO coming at 1516 UTC with K4JAZ. All Eric's QSOs were CW made at the 5-watt level.
Eric recorded a temperature of 44°F during the operation.
