[Elecraft] K3 Internal Keyer vs. Straight Key

[Don Wilhelm]

  Jim,

As another asked, please tell us more about what you are calling the 
"serial to straight key cable".

On the K3 (unlike the K2), there is a separate jack for the straight 
key, and no menu changes are required.  Both are active. and there is no 
need to turn off the internal keyer in the K3.

The N3FJP can use either the Winkeyer, or it can key using a serial 
port.  Normally applications will use either the RS-232 DTR or RTS 
signal for keying.  Check your application and see which one it uses, 
and then go to the K3 CONFIG: PTT - KEY menu and set the appropriate one 
to ON.  Plug a serial cable between the K3 and your computer (you will 
need that anyway to load firmware updates).  No need for any cable 
connected to the K3 key jack.
OTOH, if you have the Winkeyer (and you are calling that a serial to 
straight key cable), yes, that will connect to the K3 key jack.

73,
Don W3FPR
