Aurora, 50 MHz and the Elecraft P3
Tonight had nice aurora conditions on 6 meters due to a geomagnetic storm. The Elecraft K3/P3 combo did an excellent job in showing how wide the bandwidth of these CW signals has become after having been reflected off the aurora.
The first image shows the green cursor on SM7FJE's signal, the bandwidth is almost 1 kHz.
