Hi Bob,

>I wonder if you or anyone has worked T/A with CW by ear on 137?

   I don't think anyone has ever made a cw contact by ear across the
Atlantic,  but I've gotten sporadic reports over the years that my signal
is occasionally audible on a signal peak, but the peaks are not really
predictable. Also, I don't have a quiet enough QTH to hear 137 kHz signals
over that distance.  Best bet would be if Joe VO1NA ran some power - he has
an easier and shorter path to Europe.
