Hi all,

there is an interesting article about the improving perceived loudness by
6dB and that of the background noise by 3dB, resulting in a net 3dB
improvement in the signal's SNR on CW...

BTW: be careful as there are a little mistakes in frequencies difference for
fourth chord etc.
1) CQ Jan 18, page 17, Fig.1. (b): 697Hz-523Hz=174Hz (almost fourth chord)
and NOT 80Hz as described
2) CQ Jan 18, page 18, Tab.1: eg. E4-F4=19.6Hz NOT 19.55Hz,
F#/Gb-F5=41.533Hz NOT 42.53Hz etc.

Is there somebody who configured his K3 for that and tested it already?
