João,
the amplitude correction factor is not dependent on the frequency in
SDRadio.
The phase adjustment is, in the sense that what is applied is a fixed
delay (adjustable in the calibration panel) which translates into a
phase adjustment depending linearly from the frequency. Rocky and
other programs try to do an automatic balancing of I/Q amplitude and
phase, which may work well or not, depending on the nature of the
incoming signals. I will experiment on this route for my other program
Winrad and, if successfull, the routines will also be transplanted
into SDRadio.
