Understood, but it was suspicious that I get exactly 0.0 unless we have fudge factors in place somewhere or the latencies exactly cancel. I can tweak the latency of the loop back itself but not the channels used by the two copies of WSJT-X and the channels they write/read. > > I don't see this as a very big issue; I was just trying to understand > the details of what's happening. Perhaps it is as simple as the latencies cancelling out and a synthesised sample stream needs to be adjusted to add in some recording latency. I have often wondered about the consequences of using a DSP Rx and he extra latency that would add to the Rx path.
