I'll take your word for it. People have been running audio racks on ssb for decades. I had not heard of the term ESSB until the FCC started allowing the increased bandwidth. You realize that most ESSBers don't like the 950sdx because without extensive modification you cannot really run a higher bandwidth on SSB. The internal DSP limits your transmit bandwidth to 3100 even though you can unlock the transmit filters. There is of course some "blow by" so there are some products that get through, but it is not a good way to good way to run that radio.
