Did you use your existing config file? :-o

According the original README file this is required for
very new installations:
        ./install.pl etc/nfsen.conf
This means in our case
        $SRCDIR-HW/install.pl $SRCDIR-HW/etc/nfsen.conf

$SRCDIR-HW/etc/nfsen.conf should be creeted from nfsen.conf.dist
file shipped with the tarball.
It contains the above %HW_params hash.
You just need to add your sources.

Did I misunderstand something?

Regards

Gabor
