I've been noticing an RFI source lately. It sounds like a short 1
second blast of "white noise" which occurs at 25 or 30 second
intervals. It appears to be there 24/7. I hear it on 40 through 17
meters. It peaks at about S7 or S8 in a 2.4KHz bandwidth. That's
pretty strong considering that my noise level at nigh in a 2.4KHz
bandwidth is only about S1 or S2. It's not strong enough for my
portable receiver to pick up so I've had trouble DFing it. I have yet
to try to DF it with my HF yagi.
Anyone have an idea what this may be?
