No transmit on 6400

I received my 6400 today.  Using SmartSDR 2.4.9 on a Windows 10 computer.  I hooked it up and all went fine until I tried to transmit using the FHM-2  mic.  No transmit at all.  It shows output using the ATU.  Contacted a local Ham who has the 6400.  We tried everything he could think of.  Used all the setting he was using on his radio, still nothing.  Does anyone have any ideas?  I did open a Help Ticket..  Frustrating to have a brand new radio that does not work.

    The FHM-2 requires bias voltage, see page 157 in SmartSDR Software User Guide v2.x for where to enable it.

    I was the local ham helping him. +20db bias was set to on. OBTW he has NO output on CW as well. TX inhibit is disabled. We did factory reset on radio and still no joy.
    Probably something simple we are overlooking?
