    At exactly 7:31am EST every day, there is a sweep thru the band, the a few seconds later my noise level goes from S5 to S9 + 5.
    Is anyone else experiencing this problem in central Ohio ?

    Does it stay there all day until sunset?
    7:30 just so happens to be when I switch to solar power (inverter)

    I am not sure i will check. The noise increases after a RF sweep thru the band.

    Local sunrise for the OP is 7:45 right now, so might not be solar power inverters.

    Do you have any appliances like a furnace set to start at that time? Any neighbors or businesses nearby that would start equipment on a schedule?

    My MPPT controller spends a minute or so 'searching' before it fully kicks in to charge mode.

    if it's at exactly the same time every day, you can count out ant natural sources like the Sun. It has got to be man-made.... and a Solar Controler does make sense.

    Depending on where you are located, it could also be a commercial, retail, or restaurant firing up their lights, computers, ovens or whatever.

    Mine is on an actual timer. Between 7:30 and until when the sun starts generating enough power the system is operating on batteries.

    I'd suspect a grow operation and LED lighting nearby.

    Ganja grow lights. Take up smoking dope and you will not care. In fact the ganja is so good today, listening to noise is a great pleasure, as it comes in colors and patterns. You can even talk to the dead. Ohio has legal ganja, smoke it while you can.
