Long time I didn't checked this part of code! :) But you're 100 % right, 
Win-Test does only support the same format it uses to save messages. If 
you want to record the messages using an external software, you should 
configure it to save files in PCM, 8 KHz sampling, 1 channel (mono), 16 
bits/sample. It is maybe possible to get WT reading any WAV files if 
someone *really* need it, but I recognize that I wonder whether that is 
really necessary to improve that.

Thank you for the correction regarding the MSG0.WAV associated with F1 
key and so.

That might not be clear in the "Interface configuration" window, because 
only *CW* is indicated. To enable PTT output on the COM port the radio 
is connected to, click on the "configure" button right to the COM port, 
then check "Enable CW on COM port". That way, PTT information will be 
present on the RTS pin (#7 on DB9, #4 on DB25).

Hope this helps

PS : I'll try to get the '847 supported this week end.
