[Elecraft] Software CW in K3 and KX3 and contesting

[Ignacy]

That RUMped works well with KX3 software scheme means that it can be done.
Even if not perfect, this would stop taking other interfaces/CW keyers,
cables, etc. If KX3 is small but extra boxes take twice as much space, how
good is it?

So it seems that there are 3 approaches to contest CW with KX3:

1. Extra keyers

2. Changes to contest packages

3. Modified USB/serial cable (most likely)

For the last point, it seems that KX3 control port is just serial port with
RX/TX at 4800 baud, changeable to 38.4k.  If one has a plain USB/serial
cable, one needs to concoct two cables: one for RX/TX and the other for CW,
possibly with a  transistor buffer. I am not sure whether something like
this has been suggested in another thread.

4. Option 3 made as new cable by Elecraft. 

Option 2 is best IMHO for KX3 followed by 4 if we convince Elecraft (or
third party) to do it.
