[Elecraft] K3 Internal Keyer vs. Straight Key

[Bill Conkling]

NO need to turn off the internal keyer.  I made my own serial cable to key
my K3 from the computer via N3FHJP as well as other programs, plugged into
the "Key" jack.  Keep the Bencher plugged into the "Paddles" jack as well.

The cable is real simple, uses a 2n2222 transistor and a 1.2K resistor in
the base.  Works well.

Dumb question here!

I have a K3/100 #4401 and I am using N3FJP software.  I just purchased the
Serial to Straight key cable. The setup instructions says the internal keyer
must be turned off.  I see nothing in the manual on how to do that.

Also, on the rear panel there is an input for paddles and one marked key.  I
believe that is for a straight key/PC, etc.

How do I turn off the internal keyer?
Or, can I keep the paddles connected (use when desired), plug the cable in
the "key" input and use the software & PC?  Have both connected at the same
time?

Thanks in advance,
