K2/K3: Keyboard to CW possible with KUSB and no computer?

[Andrew Moore-3]

Does the KUSB option allow you to connect a USB keyboard to the K3 (or K2
for that matter) and perform keyboard-to-CW without the aid of a PC
inbetween?

If not, would this be a relatively easy future enhancement to either rig? (I
know there isn't much K2 development going on... just asking)

I know USB doesn't often play well with CW timing, but maybe a buffer could
help even at the cost of a slight delay from keypress to CW output.

The benefits of being able to do keyboard CW without the PC involved are
less power and noise, less equipment, more efficient, more portable...

No, the KUSB is just a USB to serial adapter.
I would think adding that to the K3 would be some considerable effort and would guess many would not bother or would just use a PC for the purpose.
I would expect there to be some kits around and they would probably have RS232 interfaces, so a KUSB would not be needed

Andrew,
Keyboard connectivity is not yet supported by the K3 however it has been
mentioned by Elecraft to be on their wish list. In fact, the P3 has already
been prepared with a cutout on the rear for a future USB port that hopefully
will accommodate keyboard ops. For those without a P3 I'm not sure how
Elecraft might offer keyboard connectivity and based upon my discussions
with them I don't think they've ironed that out yet either but I am sure
they're working on it. In time I'm sure they'll discuss it with us all when
they're ready.

I think a good solution in the meantime is to resurrect this K1EL K40, strip
it down to the bare minimum (the keyer board, and ditch the display) and
mount it inside a small PS/2 keyboard.

Warming up the soldering iron...!
