[Elecraft] K3: new to wish-list - KEY OUT setting in menu (to be more like PTT OUT) for CW PTT mode

Hello Elcrafters,

it was tested that KEY OUT port (rear panel of K3) is not in CW PTT 
mode acting as PTT OUT (how was wrongly supposed to be) and this was 
confirmed by Elecraft as intentional behavior but that if there will 
be some feedback/requests from customers, maybe will be possible to 
set this in Menu sometimes later.

You have my vote - I have already sent email to them on this. At first it
seemed that they did not understand. However, I am not holding my breath on
this one.

The KEY OUT switch (FET) is from the inverted state of the main receive
control line.

So your amplifiers and transverters (etc) are keyed up whenever you are
**not receiving**
- which is not quite the same thing as transmitting (!)

So when you program the keyer messages it turns on this output.
When you load a new MCU program in, it will key up your equipment for 3 
minutes continuously (I will not do that one again !)

Anyway, I think a wiring change is required for this one. It would be easy
to change the logic to be:

not_receive AND transmit

by one cut-and-jumper
