This independent and simultaneous CW keying of the KX3 is very interesting.  


Using the paddle option on the KX3 simultaneously with the Keyer 3.5 mm port for CW contest logging is a great and simple set up for logging program keying the key port configured as a straight key making the fill ins process easy.  However, I have found my configuration to where I use my regular keyer into the KX3 or K3 Key port a preferred way for maximum flexibility.  I can use the external keyer for additional memory messages in addition to the memory messages that are sent by the logging program.  The keyer has an opto isolated straight key input port where I plug in the CW output from computer based program.  The three wire serial output from the USB to serial converter cable from the computer is broken out with a SUCCI-R module that provides the CW, PTT and Foot Switch ports to interface the radio along with the TX/RX serial data.   The K1EL and MasterKeyer MK-1 or any other keyer with a straight key port will work for this application.  Yes, your suggested configuration using the accessory keyer paddle mounted on the KX3 keyer paddle connector and at the same time, the keyer port set up as an independent straight key for logging program keying is simpler but here m alternative provides more versatility.
