There is a menu setting that can be different between the two. Inp on the first menu can be set to PdLn or PdLr, or HAnd. Also if one goes to the menu Inp and then does a "hold" on EDIT, tapping DISPLAY will toggle and show the resultant state of Autodetect feature, which will allow both straight key and paddle to be hooked up to the rig at the same time if turned on.
See http://www.elecraft.com/manual/E740001_K2%20Owner's%20Manual%20Rev%20I.pdf page 99 and elsewhere. Also do NOT attempt to make sense of what happens if a shorted state exists on either paddle lead when the rig is turned on. If either paddle lead is shorted when the rig is turned on, the K2 will abide by a firmware directive not to key the transmitter with a key/paddle assertion in force when it is powered up. So as soon as you key the rig, the shorted state is now paid attention to. This initiates the behavior you refer to. Easily caused by using a mono plug instead of a stereo plug. 73, Guy.
