- Depending on your station and antenna setup, band changes might
require other switching besides retuning your radio. To make this
possible in an automated way, whenever _WSJT-X_ executes a successful
band-change command to a CAT-controlled radio, it looks for a file
named `user_hardware.bat`, `user_hardware.cmd`, `user_hardware.exe`,
or `user_hardware` in the working directory. If one of these is found,

band-change command to a CAT-controlled radio, it looks for an
executable file or script named `user_hardware`. This is done using
`CMD /C user_hardware <band>` on Windows, or `/bin/sh -c user_hardware
<band>` on other platforms, where band is described below. On Windows
the first file with any extension listed on the PATHEXT environment
variable added to the file name root `user_hardware`, and found in the
directories listed on the PATH environment variable will be executed.
On other platforms, the first executable script, or program, named
`user_hardware` found in a directory listed on the PATH environment
variable will be executed.

IMPORTANT: The use of the PATH (and PATHEXT on Windows) environment
variables is a new feature. To emulate previous behavior make sure
that the location of your user_hardware script or program is on the
PATH environment variable used by _WSJT-X_.
