Jerry, I've since learned that this is a "bug" with the 1000MP and 1000D.
As I said in one of my posts, you can simply unplug the key line and you
will see that WriteLog is correctly asserting PTT/xmit via the CAT port
throughout the entire cw message.
I might be mistaken, but it appears to be impossible to use CAT port PTT to
control xmit keying on one or two FT1000D/MP's. A separate PTT line to each
radio or LPT1 A/B relay switching with break-in is necessary.
BTW, the N1MM logger program shows the exact same behavior as WL in this
regard.
73 & Happy Holidays,
Barry N1EU
