Is their a computer program that works well for CW with 6000 series radios?

The advice above for decoding is spot on. Learn the code, practice use the programs as backups when needed.

For sending, I have to recommend FRLogger. As the author and a CW freak I worked **** the CW panel. It does things that CWX cannot do. It's free. Even if you don't use the logging or any other features the CW panel will make you happy if you want to send via keyboard.

CWSkimmer and Slicemaster are the solution that works here. Skimmer uses a lot of computer resources. Skimmer' decoding capability drops off as signals weaken. 20 word per minute capability is the absolute minimum necessary to work DX. 25 to 30 wpm is the speed of much of CW DXing. Achieving those speeds requires a very significant investment in time. It's an accomplishment worthy of respect. But time spent learning CW is time lost to exploring all the rest ham radio has to offer. To work CW for DX all you really need to know is your call. When you hear your call, the DX is asking you for a contact. Hit your exchange macro and you're in the log. This attitude about CW is just this ham's opinion and not an effort to start any arguments with the CW enabled, all of whom have my respect.
