Amateur radio is about communicating, regardless of the mode.

Chokes don't solve an RF noise floor issue if the RF noise is generated by
devices you don't own or control.

For my station, and I have space for it, everything is choked, and I mean
everything.  I bought cases of chokes.  Yes, they helped all I could

The other thing is that the bulk of the 160M dx on a given night might just
be on a digital mode.  There have been nights I could only hear 1 or 2 CW
signals, and they were in North America.  Yet, on JT65 there might be 10
new countries show up over the period of an hour or so.  It is actually
pretty impressive.

Regardless of the mode, they are still valid contacts.   No one said that
everyone had to do it.  It is about options, and there are many.

I am also suck at CW.  Yes, I have done it for 45 years or so.  I can do
it, but I don't enjoy it.    I have have some CQ WPX CW contest paper to
prove it.  LOL

Amateur radio is many things to many people.  No one said you have to
comply or like or even do all or any.

I think that putting down phases of the hobby that others take enjoyment
from is really not productive.
