Hi Marco:
Did you follow the steps to record a reference spectrum first? You
have to record a minute or so of noise in order for the program to
be able to compute gain figures which are then used to flatten
frequency response. I am not sure what would happen if you
activated reference spectrum without recording it first.

Hi All:
There is a pretty good article on the why and how of reference
spectrum use by Bob KA1GT at
http://www.bobatkins.com/radio/WSJTX_flatten.html. His site is
targeted primarily at EME and UHF-and-above users, but the
information applies to use of the reference spectrum at HF as well.

Hi Kevin,
I found this topic very interesting.
I've followed the step by step described in the article by KA1GT
but when I click on Ref Spec my WSJT-X crashes!
I'm using WSJT-X 2.5.0 on Linux openSUSE Tumbleweed.
Regards,
Yes Kevin!
For this reason I went disappointed:
I followed the step by step from the URL you shared here regarding
how to create a reference spectrum and then I checked that a new
refspec.dat was produced inside the folder, but it seems that
something in such file is not appreciated by WSJT-X and it keep
crashing until I renamed such file to refspec.old.
marco@localhost:~> find ~/.local/share/WSJT-X/ -name "refspec*" -exec ls -la
{} \;
-rw-r--r-- 1 marco users 204045 16 ott 19.35
/home/marco/.local/share/WSJT-X/refspec.old
I don't know why, I know that in this way it works!

Hi Marco,
send me (g4wjs <at> classdesign <dot> com) your refspec.dat file that
causes a crash please?

Hi Bill!
I'll do it!

Hi Marco,
your reference spectrum file works FB for me, I don't see any issues
with it. Here is the plot of it from the Equalization Tools dialog:
