Ray,
The N3FJP software works well with any screen reader.
I am just beginning to dabble a bit with NVDA for the exact license
issue you mentioned, so I am by no means a power user of that program
yet. However, the Amateur Contact Log software was one of the first
things I tried with it, and it worked fine.
For Field Day, my club used an old laptop of mine for one of the
logging computers. That machine has System Access on it, so that is
what I used to log my contacts this weekend.
