locked Re: FST4 modes with TS-890S - slow RF envelope rise problem #txaudio


Peter Hall, VK6HP
 

Thank you to the WSJT-X team for incorporating a "no shaping" option into v2.3.0.  It will be greatly appreciated by many FST4 and FST4W users. Reading the release notes, the comment is:

 FST4/W: Disable envelope  shaping at start and  end of transmission
   when environment variable FST4_NOSHAPING=1. Works for fst4sim too.

Not being a Windows power user, I wonder if someone might tell me the easiest way of setting the required environment variable?  My WSJT-X 64-bit installation is pretty standard, with default paths etc.  The v2.3.0 manual gave some clues about the use of environment variables for other applications but I must admit that a quick search hasn't turned up the variable list I was expecting.

73, and thanks,
Peter.
