[Elecraft] KX3 Question about use of ESSB for Data Modes

[David Box Comcast]

I am having a lot of fun learning as much as I can about the KX3 and really enjoy using it.  I have been playing with PSK-31 and using the Data mode with FlDigi.  The frequency range I am able to work is about 400Hz on low end due to receiver roll off and then the upper transmitter bandwidth is 2950Hz as the power rolls off sharply above this.  So I have set my waterfall in FlDigi to display 400 - 3000 Hz.

That range works very well and making contacts but was thinking tonight if the ESSB mode would broaden the available frequency span.  Not a fan of ESSB on voice but are there any negatives in using to extend bandwidth on digital modes like PSK-31.  I'll probably run some tests tomorrow but wanted to query the vast experience base of this group and see if this had already been checked.

Thanks,
