SkookumLogger v3.6 now available

Bill Myers, K1GQ has released version 3.6 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 3.6 2022-07-11


  • Support for “weekly” contests, allowing creation of new logs with correct start dates when creating the log after the start of the event. Thanks W2RU, AI6W.
  • Items on the radio menus for K4 TCP and FTdx101MP for toggling main and sub receiver antennas.
  • Items on the Radio 1 menu for K4 TCP for stepping M.RF and S.RF in 3 dB increments, beginning with the values read from the radio when enabling the connection and when changing bands.
  • Sub-receiver tracking in 1T2R for FTdx radios. Thanks NE6NE.
  • Logging a call ending in “/R” marks that call as a Rover.
  • World Radiosport Team Championship 2022 contest, currently using the same rules as WRTC 2018.
  • RSGB 6m CW Contest.


  • Enabling a connection to a WinKeyer now displays the type of keyer, and its version in major.minor format.
  • When the “Do not use the SCP database” option is on, also disable use of the Exchange Database. The option is automatically enabled for WRTC and CWT. Thanks AI6W.
  • Revised SkookumNet to adopt changes in Apple networking security.
  • Updated rules for Salmon Run. Thanks W6OAT.
  • Removed use of Caps Lock to toggle Keyboard Mode, introduced in version 3.5.
  • Removed the “all your QSOs are outside the contest period” feature, introduced in 3.5.
  • Removed Panadapter overlays for K3+P3.


  • Editing sent exchange fields in the Sent Exchange Editor was badly misbehaving, with some entries overwriting other fields, tabbing between fields skipping over editable fields, and garbled Morse Sent Exchange Templates. Additionally, the Sent Exchange Editor was not being properly reinitialized when changing logs. Thanks KD5YPH.
  • File > Export to Numbers… was failing with an error message about ASCII encoding. Thanks W6FB.
  • When the “Do not use the SCP database” option is on, also disable use of the Exchange Database. The option is automatically enabled for WRTC and CWT. Thanks AI6W.
  • When starting SkookumLogger and a previously enabled WinKeyer was reported as not available (because you unplugged it), SkookumLogger was failing to reset the enabled state to off. Thanks AI6W.
  • The file embedded in 3.5 for adjudicating a CWT log was malformed. Thanks AI6W.
  • File > Statistics Report was crashing SkookumLogger when applied to a log with zone multipliers. Thanks JH5GHM.
  • The Section Checkoff window content wasn’t being reset by Log > Reset Log. Thanks W22RU.
