Thetis v2.9.0.6 - SDC Skimmer - frequency difference

Postby iw7dmh » Tue Oct 25, 2022 7:52 am

Hi,

I would like to highlight a problem I had configuring SDC-Skimmer to make it work with Thetis.
Everything is fine configuring SDC Control Type with "Audio + TCI". Anyway I noticed a little frequency difference in the signals shown in SDC and the signals shown in Thetis panadapter.
With the help of Yuri I found out the issue is caused by the CWPitch offset that probably isn't considered when the DDS frequency is conveyed in the TCI channel.
I did a correction in the source code, as you can see in the picture below, and now the the two displays are in sync. I don't know if this is the correct or the best code correction, I just would like to point out the issue.
