I just installed 4 LUTRON dimmers here during a remodel of the kitchen and
dining rooms. As soon as I get power to them and get them working, I will
report to the group. But based on someone else's experiences with them is
why I bought just this brand at $29+ a copy. Hopefully I will get my
money's worth and won't even NOTICE THEM at all. - Mike

Jim,
Full disclosure: I have not purchased dimmers in at least 5 years or so.
OTOH, my house has 4 dimmers for incandescent lights and 3 speed controls
for ceiling fans (these are wall-mounted like a lamp dimmer - not remote
controls). I have had zero RFI from these units, and they are all Lutron
brand, Decora style, with internal neon lamp illuminator and a very small
slider (for the dimming action or speed control). I had to replace one that
was original to the house (now 13 years old) and the other was for a ceiling
light I added.
I have 2 portable AM radios that I use around the house. Neither of them
has heard a peep from any of the dimmers or speed controls. I also have an
AM/FM tuner that is part of the stereo system, and it has a loop antenna for
AM. That loop sits close to the wall, and I believe that there are Romex
power wires in that wall. If I am listening to a weak AM station, I can
hear a small amount of buzz from 1 dimmer or speed control, but that's it.
The AM radios are my best RFI indicators, since the HF antennas are far away
from the house.
I had several Lutron dimmers in my house back in IL. All of those were the
rotary knob type. I managed to burn out a couple of them, but again, no RFI
to radios.
As I recall, in all cases, the packaging on the dimmers I bought said that
they had RFI suppression. My guess is that it is pretty simple L-C
filtering, but it seems to be effective. I would suggest that your neighbor
go buy one dimmer that says "RFI Suppressed" on the package and try it
before buying many of them. The decors style Lutrons are not cheap - I
think they are around $30 or so these days. However, they seem to be worth
the cost.
My 2 cent's worth and of course, your neighbor's mileage may vary.

I'm looking for some of these for a neighbor ham. Looking for first
hand experience from someone who knows for sure. :)
