    If you watch the posted video at around 1:05 min. you will see the white noise hash is also present on other bands.

    So no, it's not just occurring on a single band.

    Naturally, as you go higher in frequency there's a reduction in the signal strength of the noise, but it's still there.

    Such noise levels are also often dictated by the antennas and how efficient they are at various parts of the spectrum.

    I can blind-switch my own antenna switch at home (without looking at it or paying attention to its position) just listening to "band noise" on my receiver(s). When the "right" antenna is selected, the noise picks up.

    That includes signals, atmospheric noise, and also RFI!:p

    Correct.

    An antenna is going to pick up the noise with greater signal strength on the band the antenna has been designed and optimized for.

    Buzz or hash? All I hear when I do that is the buzz... To hear the hash I have to hold the portable radio close to my Modem/Router.

    A properly applied strip of duct tape can greatly reduce noise.
    Dinner might be a bit late tho.

    any noise on other bands don't bother me they are not bad but sense I talk 3.810 I can only hear people that are running amps and can get over my noise level.

    Sounds like moving the antenna is the solution. VWM suggested rigging a temporary dipole antenna further away and see how that works. I would add that making it at a right angle to the power lines would help a lot too.

    That is normal. :rolleyes:

    Maybe a seperate receive Loop might be an idea - you could null out noise possibly with a small rotator? Something like a Wellbrook or an MFJ receive only loop. Or you could make your own?
