My I/Q diagnosis looks much worse. I can see the 90 deg phase shift clearly but the signals are extremely noisy. My receive sensitivity seems to be fine though. I compared it to my K3 with an antenna switch and it’s very close with the K3 having a slight edge. That said, the receive audio is pretty nasty compared to my silk smooth K3. Listening to CW on the QMX for half an hour gives my a huge headache.
