Off the top of my head, I don't think that sunspots in and of themselves
will be a problem much of the time. However, some kind of backup is needed.
Having spent a portion of my life on the transmitter end of loran, I
understand its limitations...but I have to wonder...how often will solar
activity and precip static coincide when I am flying? The odds are pretty
good in my favor.
