Finally a way to remove the wire from computer to 6000 for N1MM CW keying. Two problems were encountered:
First was user RTFM re engaging WinKeyer in CAT. No matter what I did nothing would key RF but would trigger PTT with no problem. Once I found the hidden "Advanced" and the WinKeyer setting this problem went away.
Second my testing method was to use CTL+T to trigger tune. Eventually I found the CW function keys worked properly. Tune still does not work. Another user error?
SSDR "TUNE" is a working option; just not as convenient.
