2.5.2 2020-04-03

New features

SkookumLogger now supports the new RSGB Hope QSO Party CW, SSB and RTTY contests. The first event occurs on April 6.


When you entered a value for Grid in the Sent Exchange pane of New Log preferences that wasn’t a valid Maidenhead locator, SkookumLogger was silently using the locator for 0 latitude and 0 longitude. Now SkookumLogger informs you in the Information Window that what you entered is not a valid grid.

You can now enable/disable use of the macOS Location Manager to automatically set your grid when your computer moves to another grid. The option is “Use Location Manager” in Logging preferences, and requires WiFi. New grids are noted in the Information window like this:

  • Grid updated to FN43in98 with horizontal accuracy 65.0 meters
  • New grid FN43in98 is in Carroll county, NH

The conversion of grid to geopolitical information requires an internet connection.

Misfeatures fixed

Setting Grid in the Sent Exchange pane of New Log preferences was dysfunctional. You must enter at least two letters followed by two digits, optionally followed by two letters, and that optionally followed by two digits. Tap tab or return to apply edits.

In the Countries file, the multiplier code for calls that were associated with both a WAE country and a DXCC country were incorrectly identified. For example, in RDXC, 4U1A was OE instead of 4U1V. Thanks WA1Z.
