    if the message is every time on 80 meters, there may be an issue with the filter module. Open a ticket for further support.

    I had alarm High SWR on 80m and the reason was burnt 50 Ohm resistor in filter block.

    This amplifier has the ability to detect faults long before the amp gets to full RF power out (about 10uS). What this means it sometimes it can find antenna issues that you didn't know you had and are not detected by antenna analyzers.

    It can also happen if there is an antenna fault that only shows up on higher power.

    It can be a cracked torroid in a balun for example.

    I would recommend 2 things. One, test on a high power dummy load and see what result you get and then follow up with a support ticket.
