Just trying a bit with my HiQSDR frontend and Quisk together with SO2SDR.
Jim implemented Rigctrl model 2 to Quisk. This makes it operate with other software like fldigi very well.
SO2SDR is a contest log with SDR bandmap and DXCluster. Worked QSO can be marked in the bandmap as well as stations spotted in the cluster.
Unfortunately I do not get IQ signals from Quisk to SO2SDR yet…
See a screenshot:
