Hi Denis
I am using the provided cables from K1EL for the WKmini. As noted, it is working with Writelog V12.x and it works with the K1EL test software as well. The computer sees the WKmini as Com 2 and Logic gets a message from the WKmin when in the Winkeyer Form setup menu - the message is "Winkey version 85 ready".
When I select the Winkey form/interface in Logic 9 and use it with either the Live Keyboard or Compose Logic keys the interface/radio in a key down state until the end of the transmission. It then releases to the unkeyed state.
If I quick click the Tune button, it triggers the interface/radio for about a second. If I press and hold the Tune button it triggers the interface/radio for the duration I hold down the Tune button.
The default "setup" of WKmin does not have the "PTT enabled". I can't imbed a screenshot in the forum, but I can email it to you if that will be of some assistance. Their user manual shows the default settings on page 6 of their PDF manual (link in your first replay).
The WinKeyer 3.1 IC Datasheet is here:
https://www.k1elsystems..../WK3_Datasheet_v1.3.pdf I think that will have the kind of info you are looking for.
Let me know if there is anything else I can test.
