Starting at about 50 Khz I am getting a wide bandwidth sawtooth looking interference up to about 8 harmonics across my radio spectrum hear in Texas since yesterday. I had to borrow a laptop last time I went ghost hunting for the power line signals that sometimes permeate my airways. I suppose I will have to do it again. I have three desktops but no laptops. I hope it last long enough to pinpoint. This is typical for low frequencies here in the San Antonio area. Sometimes you just have to be patient.

But I am seeing 153 Khz!
