[Elecraft] K3 Setting 1.00 mw with KXV3 for XV144

[rcstimson]

Group,
          I don't seem to have the steps by which one sets the KXV3's output to 1.00 mw for use with XV144..  
          Here is what I've tried: (1) Set Band to 28 MHz. (2) Set CONFIG to TEST in KVX3, (3) Set power to 1.00 mw, (4) Hold TUNE.  After a moment, the display changes from 1.00 mw to 0.84 mw and when I tap Xmit I get ERR TXG message.
          What am I doing wrong?  Has the firmware changed the procedure?  Need some direction.
