I just received my Maestro today and I have a headset to use that needs mic bias.  However mic bias does not seem to be working in Maestro.  If I use it connected directly to my 6300 it works fine.  Any ideas?  Is this a bug?  I have tried selecting MIC2 in the TX menu as well along with other combinations.

Steven is correct.  It has to be enabled in the Phone/CW menu.  I tested mine with a voltmeter and am getting 2.5 Vdc on the tip on MIC2.

See section 25.8 in the current Maestro manual.  (There the manual says 5 Vdc, which seems to be a documentation error since section 4.4.6 says 2.5 Vdc.  Tim?)
