You want to find CW contacts with lots of noise, explore those from
microwave EME. There a signal out of the noise a couple dB gets a 599
report! There are many posted on line. Look for stations like WB5LUA and
WA7CJO, maybe VE4MA, and KC8VOI.
The old WW2 surplus phones some of us started with in the 50s had an
intentional resonance about 1 KHz to enhance the tones of VLF beacons
where on way of flying routes was to match tones from two beacons that
alternately keyed. One was flying the beam when the tone intensity matched.

I had asked that question on line here a while ago.
Some one recorded a CW QSO. I took that WAV file and put it on a flash drive.
I have listened to that recorded QSO with the head phone I had. I went over to
the the Apple store with a 20 foot head phone extension cord, Plugged in my
flash drive into one of their display computers next to the head phone demo
display and listen to that same QSO on my flash drive and I plugged in one head
set after another. At that time the Bose QC-2 stood out and in fact it had
enhanced the CW town just a bit more so I could hear the last letter that was
sent.
You see, the QSO had a lot of static on it and the signal was almost faded out
towards last. Simply amazing little test.
Stay on course, fight a good fight, and keep the faith. Jim K9TF/WA9YSD
