SkookumLogger v3.2.7 now available

Bill Myers, K1GQ has released version 3.2.7 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.

  • The support page now contains a work-around for when downloading updates from the App Store doesn’t work with the unhelpful “try again later” outcome.
  • K4 TCP fixes a mode tracking bug and now supports bumping filter width up and down, toggling spot, and the SkookumLogger Panadapter.
  • The Steal Frequency command, previously available only via the XK-24 Keypad, is now available in the Log menu.
  • The YCCC SO2R window now displays the device name and firmware date when you enable the connection to a Mini. This requires new firmware; see the “About the YCCC SO2R Mini” item on the Hints page of the web site for details.
  • In Practice mode, all callers that have the same number of matched characters now call again when the sent callsign isn’t exactly matched. Thanks JH5GHM.
  • Added the File > Export Calendar… command, which creates a .csv file listing the start dates in the current year for the 338 events supported by SkookumLogger. Use Numbers to open the file and make a pretty table.
  • Added support for the RGO One radio to the Other group in the Radio Types lists. Thanks DF9TS.



  • Several internal changes to Morse keyer code to improve behavior in stressful scenarios, including aborts, use of PTT, and interleaving paddle sending with messages. These changes require updating the firmware if you are using the YCCC SO2R Mini. Thanks JH5GHM and W2RU.
  • In 1T*R, messages that automatically log a QSO now delay performing the log until the entire message has been sent.
  • Updated many RSGB and UKEI contest rules for 2022 changes. Thanks GØDVJ.
  • Updated Ontario QSO Party for 2022 changes. Thanks VE3CX (the very first time any contest sponsor has proactively notified me about a change).



  • The explanation for a suspect QSO containing an invalid callsign was unhelpful.
