[WriteLog] Pesky Message

[JE Brown]

I recently had to upgrade my shack PC.  Of course it has no serial ports. 
So I am using USB to serial cables.  This is not working out with my KAM+ 
for rtty.

I have to do something else. So I set up for soundboard AFSK.  It seems to 
working (but that remains to be tested in the next contest)  However, 
whenever I initiate Writelog, this message appears:

"Can't set wave file recording to:"

What does this mean, and how can I stop it from appearing?

Also,  who has a ready-made interface that I could buy which would enable me 
to run plug-and-play FSK with my TS850 using a com port and one of the USB 
to serial cables?  The 850 also has a dedicated FSK keying jack, which I 
assume must be used.

Are there any frequency issues, e.g. offsets which must be used on rcv/xmit 
, when running AFSK?  Or does checking the "LSB is really FSK" box in the 
Writelog setup menu take care of this?

Thanks
