6600M Receiver doesn't fully reengage after transmission

I wonder if anyone has an idea about why my 6600M receiver sometimes does not fully reengage after a transmission. This only happens on 40-m and it is becoming increasing frequent (it used to happen once a week, now it is every 10 transmissions or so). As you can see from the screenshot, the strong signals can still be heard, but it is otherwise silent. If I make a dit from the paddle, then the receive goes back to normal. It happens regardless of whether I run my PGXL or TGXL. Thanks for your thoughts.

    Hi Roger, it sounds like this could be either RFI or a problem with the rig. Can you test at low power into a dummy load? If it still happens, then you should probably submit a help desk ticket.

    If it doesn't happen when transmitting into the dummy load, then it is probably RF getting into the rig. Some mix 31 ferrites on any lines coming into the rig will likely help.
