14Mhz is by far the worst. That's why I only reported that band.
Like I said, I will know more later when I have my tower and HF yagi up and
an 80m dipole but at the moment it looks acceptable. I'm taking a risk, but
I can live with it since I can always schedule washing at a time when I'm
not operating. I would be more concerned if it were a TV!!!
BTW - The noise from the washer pales in comparison to the noise from the
LV light system in my son's bedroom (ie. the one I am definitely going to
replace). It hits S1 at 15 or 20 feet instead of 1 foot!
