SkookumLogger v3.7 now available

Bill Myers, K1GQ has released version 3.7 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 3.7 2022-08-07


  • Added the Messages > Abort command to commands supported by the XK-24 keypad. Keypad commands work when SkookumLogger isn’t the active app.


  • Added BY to the list of entity codes for which call areas are multipliers for EU entrants in the WAEDC contest.
  • Added 13cm, 9cm and 6cm to Band text commands supported by the Phantom radio. Thanks K2QO.
  • Modified the age entry to support cut number detection for the All Asian contest. With this change, SkookumLogger cannot correctly open previous All Asian logs.
  • Moved the Log Table Columns sub-menu from the View menu into the Log menu. Moved the Activity Table Columns sub-menu from the View menu into the Activity menu. Moved the Maps menu to a sub-menu in the Windows menu. Moved the Morse menu to a sub-menu in the Messages menu. This doesn’t affect any keyboard shortcuts. Removed the View, Maps, and Morse menus from the main menubar. I generally don’t like nested menus, but the prior arrangement was problematic on laptops with notches in the middle of the menubar.
  • When Keyboard Morse mode is enabled in 1T*R, the most recent-recently focused QSO entry field gains keyboard focus so that typing will immediately send CW.


  • The CW messages queue was stalling when attempting to send an empty message. Thanks W6FB.
  • Some versions of the XK-24 were not being discovered. Thanks AI6W.
  • SkookumLogger crashed if the “Table update interval” value in Activities preferences was set to zero. The lower limit is now 0.5 seconds. Thanks AI6W.
