[Elecraft] [K3] - Speaker output in various modes

[rich kennedy]

New K3 with latest firmware.  Newbie user.  HRD Software.
Situation: Set speaker output volume for comfortable sounding CW and SSB (RF gain close to 'full').  Then when going to data mode the same (CW or SSB) signals blast me out of the shack - very very loud requiring me to substantially back off both RF and AF gain.  Checked soundcard settings for both HRD and Windows7 any adjustments do not make any difference.  Help.
