clarification of SSB tx bandwidth

Barry N1EU
After reading the manual, I was hoping for come clarification on
setting SSB tx bandwidth.  If you're NOT running ESSB with bandwidth
>= 3.0Khz, your ssb tx bandwidth is determined solely by the roofing
filter you designate?  So with the stock 2.7Khz roofing filter, you'll
always be transmitting with 2.7Khz bandwidth?  DSP filtering is not
being used to allow user selectable tx bandwidths less than 3.0Khz?

Thanks & 73,
Barry N1EU

Barry,

The TX SSB bandwidth can be reduced using the TX EQ menu entry. A more
general-purpose means of accomplishing this, including appropriate menu
entries, is on my list but won't be available anytime soon. So yes,
you'd be limited to the width of the roofing filter, less any TX EQ
changes.
