At the club meeting there was a discussion of logging software for the upcoming Field Day. It is possible to manual log a limited number of contacts (ARRL has a paper logging form, but it needs to be converted into a “dupe sheet” for submission). But for most Field Day Participants, using logging software makes sense – especially if you plan to generate a pile-up!
The AARC has typically used the N3FJP software. However, the ARRL Field Day site also lists:
FDLog http://www.fdlog.info/ (watch web site for FD2020 software update)
N3FJP https://www.n3fjp.com/fieldday.html (updated for FD2020)
N1MM+ https://n1mmwp.hamdocs.com/ (updated for FD2020)
SkookumLogger (Mac OS) https://www.k1gq.com/SkookumLogger/ (updated for FD2020)
You can see a brief video talk about the N3FJP Field Day software embedded in Bob Pattison’s (K4DU) talk prior to Field Day 2017 at https://youtu.be/0wo5G0WWStk. The discussion of logging software is starts around 13 minutes and 15 seconds into the talk.
