K3 PTT CW

Is there any setting in the K3. using an external CW keyer and PTT, that can be used to make the key inactive while in the receive mode? As is, while the PTT function at first glance seems to work normally, it is, in my opinion, incomplete in that closing the key while receiving turns on the transmitter. For reasons that are both personal and compelling I will control the transmit/receive function completely by a manual send/receive switch of some kind.

I can accomplish what I want by using a double pole switch, one pole for the normal PTT and the other pole in the key line. I am trying to save myself the trouble of installing such a switch--getting lazy in my old age.

Any help will be appreciated.

I'm not sure about the K3 because I don't have mine
yet, but all I have to do with my Kenwood TS-850 is
turn off the VOX and use the Send/Rec switch instead.
I don't do that, but it works. The side tone still
works, but it does not transmit.

If you decide to install that switch, just use it to open the key
line. Then TX requires closing that switch plus activating the key.

Hi Paul,

this is what I discovered and described on

http://www.zerobeat.net/smf/index.php?topic=215.0

There are some possibilities that later after more important changes
there will be some change in firmware to set KEY OUT as "pure" PTT out
port. (I hope so).
For many oparators running special and complex system is RX/TX
switching by hitting the Key not so comfortable :-(
Now I have ready small switchbox to activate PTT and Key (using K3 as
EME main tranceiver on 1296MHz) to avoid unwanted keyng of all the
line of relays in transverter(-s) and mast preamplifiers.
During digital mode there is PTT via RS232 port running but is better
to remove Key at all from the RIG :-)
