[Elecraft] K3 choppy CW

[W0MU Mike Fatchett]

The key is a decent computer.  There are many people using very old
computers with minimal ram and cpu speed and they wonder why they have
issues.

Some people do not have days and hours to figure out why something won't
work especially leading up to a contest, for them a WinKeyer might be a
great solution.  To each their own.

Just because it works for one does not mean it works for all.  Shall we talk
about slopers?  :)

YES!  I'm a very active contester, and I've never used anything but 
serial port keying when using a single radio from a single computer. CW 
sounds just fine at any reasonable contesting speed. The ONLY time I've 
ever had choppy CW is running TWO radios from the same laptop computer 
on two ports. It worked, but it was choppy in the way, and to about the 
same degree, that ZM1A was choppy last weekend. That's a limitation of 
how the logging programs send CW. So I broke down and bought a WinKey 
-- ONLY so that I could run SO2R. There is NO GOOD REASON to buy a 
WinKey to run one K3. 

There is also no good reason to use expensive interfaces (or 
transformers) to connect your computer to your radio. All you need are 
properly wired cables and simple bonding between the chassis of the 
computer and the chassis of the radio. See
