Hi Alberto, Very nice to hear from you. Thanks for all you do to help us Hams!! Get that 1212M plugged in. You are going to be surprised. Let me know if you need the mixer setup file or anything. Yes, I get the same IQ correction with both ASIO and MME drivers except the MME doesn't work at 192Ksps. Here is the results of some correction and minimum working latency (manual and auto modes tested): testing done with PowerSDR v1.9.0 sr40 EMU1212 48 96 192 IQ corr 1 2 4 ASIO Y Y Y Laten 2/auto >22 2/auto MME Y Y N Laten 2/auto > 22 FA-66 48 96 192 IQ corr 0 0 0 ASIO N N Y Laten 2/auto MME Y Y Y Laten 2/auto >22/aut >33 EMU-0202 48 96 192 IQ corr 0 0 0 ASIO Y Y Y Laten 2/auto 2/auto 2 MME Y Y Y Laten 2/auto >22/aut >33 Hope that helps some.
