SDC CW macro with thetis/HL2

[Steve Williams]

Hi Yuri

I have been using your excellent SDC program for a number of years and all works well with SunSDR/EESDR3 s/w.

However I am having a problem with macros when using CW - All other modes work, but if CWL/CWU is selected in Thetis, the SDC macro pane does not change and remains on the last mode selected. The function keys although programmed for CW, do nothing of course.

It may well be a problem with Thetis but as have not seen any posts on here with the same issue although I have the feeling that maybe not so many are using it this way.

It's difficult for me to answer anything, as I don't have any devices for Thetis. Show the program window screenshots. What messages do you see in the SDC windows?

No messages from SDC.

With Thetis in CW mode

SDC macro does not "read" the mode.

And retains whatever the previous mode was.

If I change to any other mode (other than CW) in Thetis, all is good and SDC macro follows the change and works correctly.

Hope this helps.

I installed the latest version of Thetis and found an error in the TCI protocol of this program: the list of modulation types is transmitted incorrectly. Therefore, SDC was unable to identify some modulation types.
I added a workaround for this error to the SDC program.

Hi Yuri

What version of SDC has the workaround?  I have tried both 19.05 and 19.0512 and still not recognising CW mode.

[UT4LW Yuri Pavlov]

This will be in version 19.0514.
