    1. Firmware Upgrade
      — A firmware release in the late fall of 2020 has prompted discussions on how to upgrade and if it is necessary to do so. A suggestion: before upgrading, make a note the firmware version currently in use. The following includes a select list of links related to upgrading tophat firmware. The list is not comprehensive. FWIW I don't believe it is necessarily beneficial to upgrade firmware, but the choice is yours. User beware. Your mileage may vary.

      — Codeplugs are enigmas. Whereas it is best to learn to build your own codeplug, looking at samples can help. These repositories may be helpful. Third-party codeplug editors (below) can convert file formats and make global changes.
      — If using a sample codeplug, you may have to change the hotspot simplex frequency to conform to your area's bandplan, cf. USA & Canadian Frequency Coordinators.

    5. Codeplug Editors
      — FYI. I haven't evaluated or thoroughly tested all editors. Third-party editors that not been updated since January 2020 have been removed from this webpage listing. See my notes. Back up your codeplug file(s) before using an editor. I like, use and support N0GSG's software; recommended.
      1. N0GSG Contact Manager (manipulate codeplugs)
    6. SD Card Tools
      — I suggest using 16gb or 32gb Class 10 SanDisk or PNY cards. Don't depend upon the cheap no-name cards found in some hotspots, including those from China.
