suddenly my power does not exceed 60w

hello everyone, I'm making my first post for help.
I recently turned my FLEX-5000 back on and installed new antennas. I notice that my power on all bands no longer exceeds 60w whereas in the past I reached 100w. The software PowerSDR displays an output power of 85/90w, which is normal, but the wattmeter measures less, i.e. 60w. I made the measurements on a dummy load. The rest has not changed, my power supply still delivers 13.8v and can supply 45A. Could the fact of having adjusted my antennas with a SWR which could be high limit the power and damage the PA output? Have you encountered a similar problem? To date, all antennas have an SWR less than 1.5:1 on the bands

    well, if you only show 60W output into a dummy load, then it's not the antenna change causing the difference. Interesting though, that the PowerSDR meter shows full output.

    Maybe check with the Flex Help Desk to see if they can recommend somewhere that might be able to check/service the 5000.

    thank you for this response, I will contact support for advice.
    but before doing that, I'm going to uninstall everything to take measurements again and change the wattmeter
