NVIS Day, 2023 is coming! Ohio NVIS Day 2023 will be held Saturday April 22, from 10AM until 4PM EDT.
The purpose of NVIS day is to construct and try various antenna ideas, all working as NVIS (Near Vertical Incident Skywave) antennas. These antennas are low to the ground and provide coverage generally within a 400 mile radius- extremely important for regional HF communications in an emergency.
