[Elecraft] KX3 independent and simultaneous keying for computer logging on CW

Your Winkeyer with it's flow control features is something to consider if your relying on the internal KX3 keyer.  That may be simpler for those who already have the Winkeyer.  I'm happy with my MK-1 alternative.

I think connecting both your paddle and PC to a K1EL or equivalent winkeyer is a 
better option. This way, when you switch between PC and paddle sending, the 
speed will be the same. Also, I found keying the KX3 directly from the PC 
sounded a bit "choppy", as the timing of the dits was too short. The Winkeyer 
has a compensation setting which makes the CW sound much better.

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 configurati

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.
