How is your shack grounded?
You'll find some adaptors on my QRZ page which you can use that can help.In the
FT-991A case you can use the USB A-B adaptor which will break the USB shield
connection to the rig and then you can use a-a cables instead like USB 3.0
cables which have better shielding
Perfect!
That seems to be the issue. Set power down to 5W with no issues at all. Back
up to 50W or above, and problems again. Ordered some ferrites and should be
good to go! Didn’t even think of this as I have been very careful about
grounding everything. Both the radio and tuner are groun
That’s a question of RFI !

database is this one:

QST, November 2010, pp. 30-32.
A copy of the paper's manuscript is a
Jason,
This sounds like a textbook example of RFI getting into your computer or USB
cable. I had a similar issue on 80m and found that a few well-placed ferrites
on my USB cable fixed the issue.
Search for "FT8 RFI" for other folks advice.
To verify, try transmitting into a dummy load or at _v
WSJTX Version: 2.5.4
OS – Mac Monterey 12.3.1
Radio – Yaesu 991A
SiliconLabs Driver – 6.0.2 for Mac
When tuned to 40m (and only 40m), using FT8, the software loses CAT control
shortly after transmitting. The symptoms are that it will hold the transmit
too long and eventually show ORANGE status
