Yes, I made myself some and that fixed, for example, the problem that
none of the modules at the south end of the house would work after I
bought a Dell inkjet. I wonder how that thing ever made it through EMC
cert. But with a vacuum cleaner or a margarita mixer that's not easy.
You never know where these are going to be plugged in.

Well, my tolerance level for sloppy electronics design is quite low.
They could have done a better job without increased cost for that
filter. Some day (when I have a lot of time) I'll design a little preamp
that fits over the IC and provides some real filtering. Reducing the 6dB
bandwidth from tens of kHz to just a few kHz makes a world of a difference.

It also depends on what you yelled. Maybe she conveniently could not
understand :-)))
