SkookumLogger v3.4 now available

Bill Myers, K1GQ has released version 3.4 of the contest logging software SkookumLogger for macOS.

SkookumLogger is a full-featured contest logging program suitable for the most demanding contester. It runs on MacOS, supporting single-mode and and mixed-mode events on 13 bands between 160m and 23cm.  SkookumLogger requires a K1EL WinKeyer or a YCCC SO2R Box to send CW.


Apple changed something, since 3.2.5, that sometimes breaks getting SkookumLogger updates from the App Store. The update fails with an Alert about “unable to install, try again later”. One user found that trashing the version in the Application folder, and any other versions found with a Finder search, then restarting the before trying the App Store update again, resolved the problem. Alternatively, you can download this latest release here.

Changes in Version 3.4:


  • Added font and color for identifying a call that “Might be multiplier”. This case arises when call-band-mode isn’t enough information to identify dupes, and when the call is a rover. See the Fonts and Colors topic in the Log Window section of Help. You will need to revisit your font and color choices in Logging preferences.
  • Added support for the Medium Speed Test, in the nontest category. This nascent event is described at mst-contest. Thanks W1VKE.
  • Disabled Practice mode for contests that aren’t supported for practicing. The supported contests are listed in The Practice Mode topic of the Other Windows section of Help.


  • Toggling Keyboard Mode now toggles the red backlight for the corresponding X-Key keypad key.
  • The web site has moved to a far more reliable host, with the domain replacing Thanks KM3T.
  • The “Do not use the SCP database” Logging option had no effect. Now it prevents partials matching against the SCP database without blocking matching against the current log and your Exchange database. The option defaults to off and is turned on for CWops Mini-CWT and 2014/2018 WRTC.


  • Activity table column ordering and sizes were not being remembered.
  • Editing some log table fields when Keyboard Morse mode was on was transmitting CW instead of changing field content. Thanks W6FB.
  • Magic Message wasn’t sending anything in contests where the sent exchange had a location field. Thanks KK6MC.
  • CQMM was not restricted to CW only.
  • The Michigan QSO Party start time was incorrect.
  • Exchange guessing wasn’t enabled for Michigan, Ontario and Quebec QSO parties for Outside entrants.
  • Correct Mode was broken for some of the “acknowledge and log” CW messages.
