I noticed this linear sweep EMI running through 80m two nights ago. A bit
of research found it on 160 and on 40 as well. The signal is not clean and
sounds like it has some FM on it as it runs through the listening
frequency. As you can see, the sweep rate varies.
I have no clue as to it's origin. There is so much crud in our neighborhood
.
