What’s New

Version 3.10

* Alerts explain why when SkookumLogger cannot send CW, SSB, FSK or PSK messages, and cannot record SSB messages. Thanks AI6W.
* The K4 Mini-Pan window has additional features, see the Help Book. Thanks AI6W.
* Updated log submission URL for WAG.
* Handle case of more than one Panadapter video capture device instead of displaying nothing.
* Modified enabling process for WinKeyers so that special logic for WKmini Rev B keyers does not cause sporadic timeouts for other WinKeyers. Thanks W2RU.
* Corrected references to (now in the Help Book. Thanks W2RU.
* Removed control of the 2000A amplifier antenna; SkookumLogger doesn’t know which of the 10 choices to use and was choosing antenna 10 when band changed. Thanks W2RU.
* K4TCP was failing to set mode correctly when grabbing a spot on another band and the spot mode was different from the radio mode when last on that band.

Happy User Since 2014

Full Disclosure: The developer, Bill, is a long time friend and contesting mentor of mine for almost 20 years.

While SkookumLogger is new to the Apple Store, I have been using SL since 2014 just as Bill started implementing support for Single Operator Two Radio (SO2R). I've used SL as my primary contest logging program from my home QTH from casual to full-time contesting efforts ever since. Stable, great features, and excellent support of Elecraft K3(S) radios. SL has all the features you need to mount a successful contesting effort.

Great Software and Great Support

I have been using SL for several months with several different brands of radio. The program has been almost perfectly stable and has worked wonderfully with several different brand of radio. The continious updates and support the developer have be great!

I deleted the previous version and re-downloaded. That fixed the problem. Not sure what happened, perhaps something got corrupt, but it's fixed now.
