While I am not a power user of NVDA, I often try it with various 
programs just to see what happens.

That said, I have used it with AC Log long enough to determine that the 
fields and at least the basic functions work fine with NVDA. Note, 
however, that I do not yet have the logging software interfaced with my 
radio, so I can't address that part of the program when used with NVDA.
