|Coast Guard Station, Eastham, MA--note the antennae set up for a variety of wavelengths. The actual first message was sent from Marconi Station, a few miles north.|
This area is part of the Cape Cod National Seashore. Cape Cod Marconi Radio Club (+Marconi Cape Cod) call sign is KM1CC. The event is also part of National Parks on the Air (NPOTA), celebrating the 100th anniversary of the National Parks Service (also a Teddy Roosevelt thing). The NPOTA id is SS03.
I observed some of the activity yesterday. There were 2 voice stations and one CW (Morse Code) station working 10, 17, 30, and 40 meters. The frequencies are posted on the KM1CC Facebook page and the @KM1CC Twitter Feed. Volunteers were also setting up another CW rig.
