2016-12-24 "Nice" view of the local noise
Waterfall display with noise in 20m jt65 band With HF conditions being bad I chose the JT65 mode in the hope of having a chance of making a contact. None happened, and the noise patterns in the waterfall display make it very clear how much local noise there is and how the local noise sources change frequencies and power.

Transmissions take 50 seconds in JT65 and start right at the beginning of the minute, at each yellow horizontal line in the waterfall display. The only valid JT65 signal is in the top right corner right of the '1400' marker.
