Wind instrument malfunction

This does not look like a RF interference issue. I was speaking to one of our technicians and he tried this troubleshoot technique in the past. At the iTC-5, take the shield wire on the Wind connection and move it to the shield on the Depth connection in the iTC-5. This will confirm if the issue is within the iTC-5 ground connection on the Wind connection.
