SkookumLogger v3.3 now available

Bill Myers, K1GQ has released version 3.3 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 3.3:

Please open SkookumLogger after updating by double-clicking the icon in your Applications folder. Then check the version in the About window to confirm that the update succeeded. If it did not succeed, please visit the SkookumLogger support page.



  • Show the current K4 reference level in dBm in the Panadapter window.
  • Automatically send a copy of the Cabrillo log to the Super Check Partial  server when submitting a Cabrillo log to a contest sponsor. Report in the Status Messages window when the send succeeds. Optionally disable automatic sending with a checkbox in the Cabrillo pane of New Log preferences.
  • For Countries, Super Check Partial and CWops Roster databases, use the newer of the internal or the downloaded database files. The internal databases are updated when preparing a release for the App Store.
  • VE2ZEB provided code for the Quebec QSO Party, Canadian Prairies QSO Party, and British Columbia QSO Party.
  • Added support for Louisiana QSP Party In and Outside LA. Thanks W6FB.
  • The token “{0” is expanded to the content of the sent exchange Info field when sending messages.
  • All US and VE QSO Parties now provide completion lists for the Info (county/district) field in the Sent Exchange Editor.



  • Use posting to the web server instead of email when submitting a Cabrillo file to the SCP maintainer. Thanks K6TU.
  • The Panadapter window now uses any external device reporting as “UVC Camera” for video capture.
  • The KX3 poll rate has been increased by a factor of five.
  • K4 TCP uses Digital Audio commands introduced in firmware R29 in place of previous work-arounds for playing and recording voice messages.



  • The county components of the sent exchanges for inside entrants in QSO parties for Idaho, North Carolina, Washington (Salmon Run) and Wisconsin were not properly initialized. Thanks K7LXA.
  • Pounce frequency tracking in 1T*R was broken when the “Pounce frequency change creates activity from QSO entry and clears entry” option was enabled. Thanks VE3MM.
  • QSO points for FM contacts in the Ontario QSO Party were incorrect. Thanks VE2ZEB.
  • The new cutify info field feature was interfering with editing info for logged QSOs. Thanks KA1IS.
  • The VA QSO Party was mishandling bookkeeping for the mandatory off period. Thanks W2RU.



  • Use the {0 token when you are roving in a QSO party. Change your county in the Sent Exchange Editor as needed. The current county is shown in the prompt line, saved when you log a QSO, and sent in place of the {0 token in your CW messages.
  • To record a DVR message (K4 TCP), begin with the keyboard shortcut for Messages > Record Voice Message > Message n, and finish with the keyboard shortcut for Messages > Save Recording. The radio will be switched to transmit mode while recording. Recording is directed into a 90 second buffer and does not change the existing DVR message if you choose Cancel Recording instead of Save Recording.
