I don't believe I said distortion?
You said "I can hear something, but no clear output" which suggests distortion.
I said the SSB was inverted and I cannot
switch them. I have to select USB for LSB, and LSB for USB.
If you follow the links to help on the HDSDR site you will find my pages.
Close to the top (Using HDSDR) it says "Make sure that the IQ Swap (Options - Input Channel Mode for RX) is set correctly."
