[Elecraft] K3 choppy CW

[Erik N Basilier]

Hi Vic,

In my opinion, Kok Chen and you have said it best so far.
The bottom line is that someone could get perfect CW (without using audio)
from older as well as newer computers, and could repeat the feat over and 
over
on different machines, while another person has the opposite experience, 
and,
as you point out, the difference has a *lot* to do with what else is running 
on
the computer. It is very easy to assume that just because something is 
working
repeatedly for one person, it would for another person. The computer 
industry
has in effect promoted the belief that you just have to have a program and a
computer that are compatible, and you do the installation correctly, you can
forget about what else you have on the computer. Not so. Even in the absence
of unrelated software and hardware, small changes in the basic hardware 
configuration
can make a big difference in outcome; a faster processor or larger memory is
likely to work for you, but *can* work against you in some cases.
What is the best approach depends a lot on personal circumstances. You
mention gadget overload in the shack, and I have that too. You are 
apparently
willing to strip your shack computer of all non-ham activities, and the 
computer
then is a ham gadget, great! I assume you have another computer for email 
etc.
In my case, my main computer is quite fast (quad 6600 processor) and it is
located right next to my radios. It has 4 GB of memory, more than Vista 32
can use. All the time I run several resource-heavy programs on it. Most of 
the time
I get on the radio without any PC use at all, but I do use that same 
computer when
once in a while I get on the digital modes. If I were to shut down a bunch 
of software
before doing running ham software, I would be too lazy to bother doing it at 
all.
I could add another computer for hamming, but that computer would then be a
ham gadget, and a much bulkier one than a WinKeyer. Now it so happens, maybe
because of the many contesters on this list, I am beginning to get the itch 
to try
contesting with software. The other day I downloaded and installed N1MM.
The same day I placed an order for a WinKeyer. While my software and
hardware today might allow me to be one of the lucky users who don't need
the WinKeyer, the odds are against it, and I don't want to waste the time 
trying
it, expecially since I frequently change the software I run, and I don't 
want to
revisit the issue.

73,
Erik K7TV
