This weekend was Field Day for ham radio operators across North America. This is emergency communications practice for ham radio operators to hone their skills, preparing for natural and man made disasters. For the Penn Wireless Association this is 24 hours of ham radio communications running off the grid making your own power with generators, batteries and solar power powering their stations set up in tents and pavilions in Tyler State Park, using antennas that are temporarily set up on location. These emergency radio stations can talk around the world with no phone lines, fiber optic cables, no cell towers.
Here are some shots from the wee hours of the night.
