      PDSR 2.4 works, has a nice tunable filter.

      The downside - it seems to have lost the "IQ Samples Correction" on the Audio Setup tab.

      Unfortunately, this wrecks my image rejection - "Calibraton" doesn't help much, and I get the Dance-of-the-Images :(

      PDSR 1.19 has "IQ Samples Correction", where I set it to +1, at which point all images all bands are -50 dB or better. Very nice clean display, both on the air, or driven from my signal generator.

      Am I missing something for PDSR 2.4.4? Is there a way that I am not seeing to get the Sample Correction?

      Note - I am using the cheapest 24 bit sound card I could find - not because I can't afford the recommended cards, but because I learn more about SDR this way....
