KEITH and fellow Elecrafters. It has been long known that certain individules have an inablity of decerning a difference in a pitch of tones that are somewhat close to the same frequincy. This is comminally refered to as tone deafness.Thats why CWT is real handy. There are many good CW operators that are tone deaf. They can hear the tones but if the tones are very close in frequency they cant tell one from the other other then sending speed and style.
An interesting fact. in a room with 150 people being tested for SONAR which several pair of tones were played. Some tone pairs were the same frequency, other tone pairs were offset from each other. You had to mark weather the tones were same, second tone high, or second tone low.
You had to get %85 right or you failed. When the test was completed there was only 10 of us that passed.
For us that are not aflicted with this minor disablity using your brain as a filter for the pitch you want can make for good cw copy. For people that are tone deaf, get you contacts using the CWT and good filtering.
So Keith you are not alone but don't let that keep you from CW
