I have been re-reading the manual and posts on this subject, and I am
getting a bad feeling. I hope I am misunderstanding what I'm reading,
but if not, the KX3 can't be keyed by a computer via the normal means
of having the software assert RTS or DTR. If the KX3 won't do CW from
a computer without an additional external gadget its suitability for
DXing, FD, Sweepstakes, and other contests will be seriously hampered.
Most FD or DXpedition ops might leave it at home and just take a K3.
The solution proposed so far is to make a serial cable with a key plug
hanging off it, plug that into the key jack, and configure the KX3 to
see it as a straight key. Then to use a paddle, you'd need a
Y-connector at that jack and an external keyer. I have actually had a
setup like this, so I have the external keyer and the Y-connector, but
it is not elegant to say the least. Much better would be to design the
appropriate capability into the KX3. To many hams, a 10w radio is
primarily a CW radio, so this really needs to be addressed, i.e. the
DTR or RTS lines have to be available and capable of keying the KX3.
I hope that I'm just overlooking something obvious and that the
actually KX3 has the proper functionality and I just don't understand
it.
