2.6.x Release Notes

2.6.2 2020-06-23

This release has an important bug fix for K3 radios without an attached P3.

New features

SkookumLogger now allows you to specify a “device name” associated with a serial port name. Device names appear in the port choosers. See the External Devices section in SkookumLogger Help.

SkookumLogger has a new utility panel, Grid Information, listed in the Window menu. The panel shows additional information for a Maidenhead locator entered into a QSO grid entry field (directly or via prefill), or for a locator typed into the Target Grid field. Optionally you can ask for the grid to be reverse geocoded to show geopolitical information like state and county. See the Grid Information topic in the Other Windows section of SkookumLogger Help.


K3 now allows direct frequency entry for all bands supported by SkookumLogger. Before, entry was limited to bands 2m and below. Thanks K2QO.

Port choosers now list all serial ports discovered by macOS, with ports that are in use disabled (greyed out) so that you cannot try to use the same port for more than one device.

If a remembered port is not available (because, for example, you are using it for another device), SkookumLogger posts an alert when you try to enable it.

The “Autoset Sent Grid” option has been relocated from the Sent Exchange Editor to Logging preferences.

When the “Autoset Sent Grid” option is enabled, SkookumLogger periodically updates your own grid using information from macOS Location Services. SkookumLogger now compares extended square representations to determine whether or not your grid has changed significantly. The extended square (8 characters) is roughly 1 km wide and 0.5 km high at the equator. Thanks K2QO.

Misfeatures fixed

K3 was timing out waiting for poll responses from a P3 when there was no live P3 connected to the radio. The fix requires that the user not enable the “Radio Has P3” option in the Radios window. Thanks CT1DRB.

In hard-to-describe cases, SkookumLogger was mistakenly changing the adornment of a call in a partials list when changing keyboard focus. This happened for both contains matching and fuzzy matching. Thanks JH5GHM.

Changing the Grid in the Sent Exchange Editor wasn’t updating the sent grid prompt or the sent exchange morse template until after a restart. Thanks K2QO.

Changing the “Adjust pitch differences” option in Practice preferences while Practice mode is enabled caused a crash. Now, that option is disabled (doctor says Don’t Do That) when Practice mode is enabled. Thanks VA7GL.

Some Amplifier and Rotator preferences were interacting with some Radio preferences.

K3 can respond with packets that are correctly terminated but too short, causing a crash. Thanks N9SE.

Crash when changing P3 center frequency or span when radio transmit frequency is zero.

2.6.1 2020-06-15

New features

Added DVR playback support for the KX3. Thanks W8JJ.

The Radios Window has new options for the Elecraft K3 & P3 combination, described in the updated Radios Help topic.

Added support for the Yaesu FT-818, identical to FT-817 except for baud rate. Thanks K7YEM.

Added Toggle Transmit Mode, Transmit Mode, and Receive Mode commands to the Radio 1 menu. These support simulating a foot switch by tapping a keyboard shortcut. Similarly added Increase RF Gain and Decrease RF Gain commands to the Radio 1 menu. These are experimental commands for Field Day operation with SkookumLogger running at a host station controlled remotely via desktop sharing. In this release the new commands are supported only for K3 radios.


The scoring rules for ARRL Field Day have been modified for 2020 to allow non-zero points for class D to class D QSOs.

The list of ARRL Sections has been updated to include Prince Edward Island (PE), VY2. The W2RU Section Checkoff shows this new section as “PEI.”

K3 IO now sets RIT/XIT offset instead of SPLIT mode when the difference between transmit and receive frequencies is less than 10 kHz. This addresses a complaint that SPLIT was being turned on “silently” and “unexpectedly” when toggling transmit focus between run and pounce with an offset in the “to” frequencies. SkookumLogger now turns SPLIT off and on depending on the size of the offset, but does _not_ change the on/off state of RIT and XIT.

When grabbing a spot, SkookumLogger now offsets the transmit frequency down 50 Hz from the spot frequency. That positions your transmit frequency halfway between the 100 Hz quantization steps of spot frequencies, so you won’t be exactly zero-beat with others grabbing the same spot.

Misfeatures fixed

The command for merging WSJT-X ADIF into an existing SkookumLogger log was deleting all the QSOs in the original log. Thanks AF8A.

The YCCC SO2R Box radio mapping buttons for Radio 1 were not functioning. Thanks GØDVJ.

2.6.0 2020-05-25

This release has numerous internal changes along with significant changes to the user interface. In particular, there is a new Window ► External Devices menu ► with items that open windows with settings and displays for your external hardware. The windows consolidate settings for each type of device, and replace the Serial and Keyer preference panes. Considerable effort has been made to improve dealing with serial devices, including showing only those ports in Port choosers that are not already in use. All of this is documented in SkookumLogger Help.

New features

The Radio 1 and Radio 2 menus now show Increase RF Gain and Decrease RF Gain commands when the enabled radio is a K3. You can assign keyboard shortcuts and hold down the shortcut keys to “scroll” the gain, approximating the effect of twirling the knob. Thanks WA1Z.


Bad calls in the SCP database can be deleted by listing them in a text file named BadSCPCalls.txt, located in the SkookumLogger support folder. Thanks JH5GHM.

The start dates for the HQP series of events have been updated. Sorry I wasn’t able to get this release ready before series 2 began. Thanks GØDVJ.

Misfeatures fixed

SkookumLogger crashed when a known call with more than 9 characters appeared in a list of fuzzy matches. Thanks JH5GHM and AF8A.

The version date was not updating in the Database Versions window after downloading a new Countries file. Thanks GØDVJ.
