RFI ID

Anyone have any ideas what this signal (RFI) is coming from ? It just appeared a few weeks ago. It's on 20 and 40 meters. It sounds like a washing machine swishing back and forth. About 1 second oscillations of low to high pitch.

    Have you tried to isolate it to in your house or external to your house?

    I have verified this is not coming from my house. Drove the neighborhood with K3 and small magnetic loop to see if I could find it. No luck. There is a neighbor with a new solar installation but that house was quiet.

    I also checked with some WebSDR radios that are within 100 miles to me and I don't hear the signal. This is probably local.

    The signal is there 24/7. It also changes over time. The pattern changes and the interval will change. As you can see below the signal changing its pattern, spacing and strength.

    Probably no fixing it. I have a variety of unknown signals since I live next to an Army post. I set a Remembered TNF on the persistent ones
