Received your signal using just the trapped 40 - 80 m dipole and a JRC
NRD525.
See the attached picture.
Sampling rate 48000 Hz (I was testing the integrated sound chip of my
new mainboard)
FFT size 524288
Resolution 0.092 Hz
The capture spans an interval of about 15 minutes, during your high
power period. Some QSB is noticeable
from beginning to end.
