Thanks,
I got some help from a fellow that told me about adjusting the decoder threshold from
or off the auto setting. Works better now... I have been off cw for many years and have
been trying to get back in to it. Thought it would be nice to see what I was copying to
get my speed back up. I was having trouble getting the decoder to copy much of anything...
I understand depending on what is being sent, how the decoder will or will not copy.
By adjusting the threshold, and using the cwt, I was able to get it to work much better.
Thanks, for the help. Best 73' Joe / w7joe

Hi Joe,
I think the real problem is in trying to read hand generated code. If you copy CW in a contest you will have pretty good success because most of the stations that are running contacts are using their PC Contest Program (like WriteLog) to generate the code. I frequently do this to copy the 35 WPM and up guys.
I try to improve my personal code sending ability by practicing with my paddle and the K3 in TEST mode. I have a Begali non-iambic keyer paddle feeding into the paddle jack of my K3. (So I can't blame my tools). I'm looking at the K3 decoder while sending. To my ears it sounds great. But when I look at the decoded text I see the following:
When I send an "R", I frequently see EN
When I send an "L", I frequently see ED
When I send a "P", I frequently see AN or EG
When I send a "C", I frequently see NN or KE
The errors become more pronounced as I increase sending speed. I usually start at 23 WPM and work my way up to 26 or 27 WPM.
I have also used WriteLog to decode my sent code and I see the same type of problems.
73,
Mike K2MK
