V1.3 now has the ability to select either CW-upper sideband or CW-lower sideband in the setup menu.  For CW fans, it helps to have an increase in pitch as the slice frequency increases.  I take the opposite sideband and set it to the CW pitch frequency.  When set this way with wider filter bandwidths, the opposite sideband stays suppressed for really excellent single-signal reception. 

Although we've been able to independently adjust the lower and upper filter skirts to null an interfering signal either above or below the operating frequency, now the pitch shift can move in the direction of the operating frequency.

At first, I thought placement would be better in the slice flag, but since the upper and lower skirts are manually set anyway, I see no detriment in leaving it in the setup menu.  I have not tried it yet, but hopefully CWU and CWL are captured in the new profiles.  Well done!
