2.4.6 2019-07-27 New features

Katsuhiro, JH5GHM, has provided code that specializes the general-purpose Levenshtein distance code for the case of matching a partial call against a known call. For CW mode, the code also considers the distances between morse characters. The result allows ordering the list of known calls in the Partials pane by their likelihood. This alternative partials-matching approach is named “fuzzy similarity“ in SkookumLogger. See the Partial Call Matching topic in the Log Window section of Help.

When the call in the Call entry field is exactly the same as a call in the partials list, the background color of the Call entry field is changed. Use the Entry Field Background Highlight Color color well in Logging preferences to choose a highight color that is compatible with your needed color choices. See the Fonts and Colors topic in the Log Window section of Help.

The new entry field highlight color is also used to identify exchange fields that have been pre-filled. See the new Exchange Pre-fill topic in the Log Window section of Help.

Beacon CQ mode now has a pause state, entered when you interrupt a CQ while the mode is active. Tapping CQ resumes the mode. See the Beacon CQ discussion in the CW Messages topic of the Messages section in Help.

Practice mode now supports WAE for outside entrants by limiting all callers to be in WAE countries.


The mode for a spot received from DX Cluster with frequency that matches an “official” FT8 frequency is set to Data.

Log ► Move QSO from Pounce to Run now positions the cursor at the end of the call. Thanks W2RU.

Misfeatures fixed

Parsing of WWV forecast messages from DX Cluster was broken for A values with more than one digit. Thanks W2CS.

Creating an activity when changing receive frequency via clicking in Panadapter window was setting the new activity to the clicked-on frequency instead of the previous frequency.

The latest version of SkookumLogger is available free of charge for download here.
