Hi all

Patrick F6CTE the maker of multipsk have made a new qrp mode.  He has called it 
 the Lentus mode. The goal of this mode is to
perform VLF to HF communications at a very low S/N (-34 dB with a noise 
bandwidth of 3 KHz). 

The Lentus mode is incorporate in his latest version of Mulitpsk version 4.21 
beta.

Patrick has documented the mode well as he always do. You can download a 
description of the mode for my dropbox:
