I see where you are going with that, Ed. I think those
noisy devices shouldn't be sold to anyone. I'm pretty
sure all it takes to eliminate the most RFI is some smart
engineering and a 10-cent part (if even that!!). Yes, it
makes sense to eliminate the noise even though most
people won't complain about it. More...
If memory serves, W8JI lives about 6 miles from the
nearest town. When he "points" his directional 160m
receiving antennas that direction, the noise increases
by several DB. So, yeah, consumer devices do radiate far
from their sources and all of that just adds to the
noise floor of our radios. All because some manufacturer
wants to shave a dime off their cost.
