SkookumLogger v3.2.2 now available

Bill Myers, K1GQ has released version 3.2.2 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.

3.2.2 2021-09-05

3.2.0 had a plethora of issues created when I redesigned the architecture for external devices to handle both serial and TCP devices. 3.2.1 was an emergency patch to deal with a crash potentially affecting many serial radios. In 3.2.2, I’ve addressing additional problems reported by users and cleaned up other serial radio-related issues.

New features

  • Added visibility menus for each activity table to the View menu, and re-enabled the visibility popup menus on the tables’ header rows. GØDVJ provided a good example why you might not want all tables to show the same columns: he sorts on the rotator column when S&P on a band where he has rotatable antennas, and hides the bearing column to save screen space on bands where he doesn’t have a rotator.


  • The new K3 + P3 radio type implies that there is a P3 panadapter connected to the K3 and turned on. The K3 radio type now implies that there is not a P3.
  • Added support for the 60m band, recognized for K3 and Phantom radios. This prevents a crash. Thanks W2RU.
  • Revised scoring for the UKEICC 80m contest to include points for bonus calls. Thanks GØDVJ.


  • Corrupted packets received from Elecraft radios were causing a crash. Thanks KB3ZGL.
  • The Practice mode Spread settings for caller speeds and amplitudes were creating much too small variations.
  • Adding multiplier information to the Notes field wasn’t working for QSOs with county-line straddlers. Thanks NK4O.
  • Ohio QSO Party Outside wasn’t identifying calls in the eighth call area as “possibly needed”. Thanks NK4O.
  • The set of mode-dependent flags in the QSO column of the Pass Information window wasn’t depending on the log’s Cabrillo Mode setting.
  • Port names defined in the Port Device Name Editor were sometimes being reset when the serial port disappeared or wasn’t present at startup.
