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):
