Maximum input level usb audio


DAVID IW5BNL
 

Hi All,

I do some math supposing that ssb modulator is based on hilbert transformer. 
With little information available and my calculation may be possible that maximum input level is 0.4-0.5 in order to keep normalized modulator output to -1/+1.
I'm going to try IQ input in the next days..I assume that I (or Q) is right input of tx USB port and Q(or I) is left input of tx USB port.
Giovanni HB9EIK or I2PHD do you have some more informations (that can be shared..of course) on this topic.

Regards

David
