[Elecraft] No Upper side band shown on 10 meters.

[Ronald Wicker]

I am trying to get my (new to me) K3 setup and I'm having a problem with mode selection not showing USB for 10 meters.  Presently the only way to hear SSB on 10 meters,  is on the digital mode.  I have Upper Side Band on all the other bands.  I'm hoping its a easy fix.  Any suggestions on what to do.  I can't find any reference in the manual.  Any help would be greatly appreciated..Ron, AA5NI.......
