I am going to list a bunch of logging programs.
My main log is AC log by n3fjp, I pay for it , I forget how much, but it is reallya full service loggin program and a few of the hams I am friends with use it, so when I have questions i have someone to ask. Some of the Hams I know also use Prolog, and it cost some, but the ones that use it really like it. You need to decide for your self. But I did just check out this one by HamCall HCLog and it looks like a good starter logging program
