This is *extremely* amazing! Shannon et al. were right, of course, narrow BW and
plenty of patience pays off in the end ;-) I wonder what could be accomplished
in the "dark hole" (~6.5kHz) between the worst mains harmonics and the QRM DX
peak around 10kHz (despite lower antenna efficiency).

Thanks & congratulations for a great QRP achievement!
