Re: Think there is an 40 meter intermod like issue in QMX+?.

 

Bob,
?
please check also the results of Test ADC IQ. How much difference between amplitude of I and Q signal and how much variation from 90 deg phase shift? Significant variations would lead to low image rejection.
?
For diagnostics see QMX QMX_plus Audio PCM1804.
