Hi Jim, This is most likely related to opposite sideband suppression, not filter blow-by. Nominal factory calibration results in OSB suppression of around 55-60 dB. You can improve on this using a new procedure we developed a month or so ago. It requires a strong signal source on each band to be optimized. I can send you the firmware and instructions if you're interested.
