Tom,

I was also thinking maybe he got into split mode, however...... The 
button you suggest pushing actually toggles between  split and normal 
operation.   So pressing that key doesn't  tell you what mode you are 
in, it  switches between  split and normal.    A better choice to see if 
you are in split mode is to hit the key just to the right.  This is the 
  second row down, second key from the left in the block of keys just to 
the right of the main tuning knob.   If in normal vfo mode, hitting this 
key just gives a boink. If you are in split mode, this key   announces 
    the other vfo and you will hear "S" followed by   either"A" or "B" 
followed by frequency.

Hope that makes sense.

73, Steve KW3A
