Is  Controlled Envelope SSB used in the DigL or DigiU mode?

    No.  When a digital mode (DIGx and RTTY) is selected, all signal processing is bypassed.

    Thanks. I can see that actually happening, so...... is there an advantage when using a mode such as JT-8 to use USB instead of DigU, or is it actually disadvantageous?

    Definitely a disadvantage to use USB for Digital Modes as the various DSP and CESSB add non linearity's that can corrupt digital signals.

    I just wish it would remember that I change the default bandwidth from 1khz to 3khz to operate FT-8.  Maybe that is in the global settings or something.  I have not dived that deep into the manual.  I have never run RTTY, but I am guessing that 1khz is standard for other digital modes.  It is nice to have a bit of extra functional bandwidth as some people are operating slightly below or above the "designated" FT-8 frequencies due to crowding.

    I set up my FT-8 modes and save a profile with the appropriate BW, etc. Just don't switch bands with transmit selected  and ready when in the FT modes.
