And the Peaberry does TX on the same sideband as RX?

From what Dave says this seems as if the Peaberry is TXing on the wrong sideband. Not with crossed IQ?
I have re-checked both versions of Rocky and confirm it does TX PSK on USB, just above the tuned frequency. But not the other side
Confusion about IQ or QI has been with us for a long time. Switching Rocky when transmitting has only appeared with the Peaberry.
The Ensemble with crossed TX jumpers is the same as early Softrocks. With WSPR-IQ Reverse TX IQ needs to be ticked.
