Known problem(This problem is almost resolved at Soft66ADI.)

Please note for DELL PC user. If your PC does not recongnize FTDI driver of Soft66AD,
try pulling the USB plug and placing it. do it 2 to 4 times.
If USB bus power is weak, it is not enough to charge capacitor of ripple filter.
There are some noise of USB interface. 4MHz,8Mhz,12MHz,etc

There is cross modulation same as direct conversion receivers.
If tere is cross modulation, try to adjust RF gain by trimmer.
