Report preparation

• I used the AI-assisted bug report tool (Help → Support → File an Issue)
• I have attached a support bundle or log file

What happened?

When I enable CAT TCP using the Flex protocol, the MOX button on my FLEX-8600M activates. The connection to my coupler—which supports Flex TCP—also stops working.

If I select the TS-2000 protocol, the connection is successful, but the frequency is no longer transmitted.

What did you expect?

No response

Steps to reproduce

1. Open CAT Panel
2. Set Port 1 to 60010, Protokoll: Flex, VFO A: A, VFO B: -
3. Set Port 2 to 60013, Protokoll: Flex, VFO A: A, VFO B: B
4. Check the box for "en" in each case.
5. Enable CAT

PS:
Unfortunately, it is not possible to deselect VFO A for the second port (SO2R); only the options A, B, C, and D are available. However, it is possible for VFO B. Since I am using two ports, I need to be able to assign just VFO A (for SO1R and SO2R).
