I've always found that an old-fashioned logbook, using paper and pen, was the best for me. Computer programs have a way of stopping working, data files get corrupted or accidentally erased, hard drives can crash, computers can die. Books are there forever (at least until there's a fire, a flood, or rats.
) If you use "analog" logbooks you can put them on your bookshelf when they get full and refer them many years later to re-live the thrills of rare catches or other exciting moments that you've experienced on shortwave. That's not always possible with a computer program for reasons I've stated.
