This is a request for handholding. I downloaded two rpms from the American Radio Relay League, which recently acknowledged the existence of Linux. I have never installed an rpm, and I suspect that it is unlikely that I will find these programs in the repositories very soon. I found some info on the internet, followed it, and still have no clue as to how to run these programs, or whether I succeeded in doing anything.
I accept the fact that PCLinuxOS strongly recommends avoiding non-repo programs, but I have no choice. If there is a different forum or site to handle this, I will be happy to move there.
I actually need very careful supervision on this, because I have no idea of the steps required.
