[Elecraft] PX3 Span will only go up to 100Khz

[Mark, KE6BB]

Roger, 
Fred is correct.  In fixed-tune mode, the display is limited to +/-50 khz, which is a 100 kHz span. See the latest PX3 Manual (Rev. A5 dated May 22, 2015), page 21, left column, second paragraph from the bottom.  
I wasn't aware of this until I read your post and checked out the latest manual.  It won't change my decision to buy one, though.
