WSJT-X provides a tool that can be used to determine the detailed
shape of your receiver's passband. Disconnect your antenna or tune to
a quiet frequency with no signals. With WSJT-X running in one of the
slow modes, select *Measure reference spectrum* from the *File menu.
Wait for about a minute and then hit the *Stop* button. A file named
`refspec.dat` should appear in your log directory.
