[WriteLog] WriteLog-TS950SDX-FSK almost there but ...

[Igor UA2FZ]

Hi Jon,
I'm using TS-950-SDX and WL too. It appeared the same thing in the CQWW
RTTY. I have PTT and FSK keying circuit on PC port Com2 using
pair of 4n25. Reverse mode installed on TS950 menu and FSK - rev on TU type
on WL. All is working OK.
