I'm using the trial version of N3FJP and find it very easy to use. I enjoy it's automated logbook function. However, in talking to some other older Hams (my age) they had bad experience with logging software that had been in use for years that suddenly went out of business. The software and algorithms disappeared and was not transportable resulting in decades of logging information being lost forever. Some of them had such a bad taste in their mouth that they abandoned software logging systems altogether. I've been out of amateur radio for 20-25 years and realize that logging isn't even required today. I myself always liked the concept of maintaining logs for posterity. What assurances do I have that a software system such as N3FJP won't become obsolete and not transportable to the latest technology?
