WE2XGR/2 will be testing Olivia 8/250 mode on 506.5 kHz until ~ 0030Z tonight. From a website 
dedicated to this mode:

Olivia is a ham radio digital mode designed to work in difficult (low s/n ratios plus multipath 
propagation) conditions on HF bands (though it also works as well on VHF/UHF). The signal can be 
decoded even when it is 10-14 db below the noise floor (i.e. when the amplitude of the noise is 
slightly over 3 times that of the signal).  It can also decode well under other noise, QSB, QRM, 
flutter (polar path) and auroral conditions.  Currently the only other digital modes that match or 
exceed Olivia in sensitivity are some of the WSJT program modes that include JT65A which are 
certainly limited in usuage and definitely NOT ragchew capable.

Reports will be gleefully accepted.
