[Elecraft] FSK-D, Y-BOX & WinKeyer - config help please

[Kevin, N4TT]

I seem to be digging a deeper hole so it's time to come to the K3 experts
again.

I'm still trying to get FSK (not AFSK) to work. My setup is a K3s, Y-Box,
WinKeyer and Fldigi.

I think I have everything set up properly but something very strange is
happening. My CQ string is:

<TX>
CQ CQ CQ de <MYCALL> <MYCALL> <MYCALL>
CQ CQ CQ de <MYCALL> <MYCALL> <MYCALL> pse k
<RX>

What shows up on Fldigi when sending:

CQ CQ CQ de N4TT N4TT N4TT
CQ CQ CQ de N4TT N4TT N4TT pse k
TT N4TT PSE K

Note that last line. I don't know where it's coming from. And it is showing
up because tones are still being generated. The tone stops right after PSE
K (caps).

I have another macro:

<TX>
<CALL> de <MYCALL> <MYCALL> kn
<RX>

It sends:
 de N4TT N4TT kn
T KN

The physical setup:

WinKeyer PTT to Y-Box FSK-in (tied to Accy pin1)
WinKeyer KEY1 to Y-Box PTT-in (tied to Accy pin 4)

Radio is in DATA FSK-D 45 bps.

I'm not sure what else to try.
