Two signals that are the same to me at  800 HZ  just seem to move apart as the pitch is lowered.  To look at it another way the absolute difference between the two  signals has not changed  but between 800 and 400 hz tones  the percent change has doubled and, at least to me, is very audible.

>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

What am I missing here?  

Does tone-deafness cause an inability to detect the "warble" one hears
when tuning with the spot button  pressed?

I have begun using the CWT most of the time now.  Not because I can't
tune accurately with the spot tone, but because it is faster.
