The BCA (Bad Counterpoise Antenna) demonstrated. Demo of rapidly-deployed BCA on a CODAN 6110-MP radio, battery operated, closing a two way link over a 40-mile path between Windham NH and York ME. This likely propagation was NVIS (Near-Vertical Incidence Skywave), at 7.14 MHz. (January 4, 2022)
This is the Windham NH side…
What it sounded like in York, Maine…
