CW that is not at all perceptible even with the most selective ears ? If so, all my congratulations, you are the only that can do that. In case you have missed it, all this *digital stuff* is meant to make possible reception of CW where the ears can not even tell that a CW signal is present. And this is the case with 137 kHz. 73, Alberto I2PHD P.S. Have you perhaps forgotten a smiling emoticon :-) at the end of your message ?
