Amateur Radio Software problem

[schwap]

I recently installed gpsk31 on my computer.This is a program that allows the computer to interface with a radio transmitter to generate PSK31 signals and receive them. The problem is that there is a configuration file that has to be changed by the user to allow it to generate the correct text. This file is "owned" by root and I have been unable to modify it. I tried
$ sudo chmod +w gpsk.conf,entered my password and got back the message "Changing properties of gpsk.config Operation not permitted."
The only way I can see to modify this file is to do so as root because I don't even have permission to move or delete the file and rewrite another one.But of course, I can't login as root.
Any idea what's going on here?

Is this file in /etc ? Often it is possible to copy the config file to your home directory and use your own copy or you may even find there is a copy already there. Have you tried running the application itself as root? Not usually recommended of course.
