You're not likely to get much of a response here on the general mailing
list. You can try the fedora hams mailing list:
http://lists.kernelnewbies.org/mailman/listinfo/fedora-hams
But it's not really active. I don't have any experience using grig since I
mostly use fldigi but I can give it a try when I get home.
Thanks,
