Dana, The question of sensitivity still remains as far as I can tell. Can you borrow an attenuator and bring the XG1 down to the noise floor on both yours and Joe's radio. The 10 dbm difference may be a calibration issue rather than a sensitivity issue unless you can still hear signals on your Yaesu that you cannot hear on your SDR.
