I can find no way to alter the mike gain of the CSI750... of interest is that I've had several QSO's with people
who have told me that my audio level was fine. One operator suggested that it was the internet connection that
influenced the audio level; he noted that he had had QSO's with others who had too low or two high audio and
his conclusion after multiple discussions and investigation is that the connection and service is the modifier of
audio level. If you know of some way to adjust the mike gain on the CSI750 please let me know.
