----- Original Message ----- From: "Daniel Jackson" >think of filtering the I/Q to the TX if the images are at frequencies outside the desired audio bandpass.
But this is not possible, the soundcard "audio" producing the image is at the same frequency as the wanted signal. It is the phase difference in the I/Q signals that should produce near enough zero RF at the image. Check that I & Q are present at the same level. The fault is likely to be due to a component or circuit problem. 73 Alan G4ZFQ
