    Here’s a previous thread on the same subject (under Related Conversations), and it includes the Flex official answer.

    https://community.flexradio.com/flexradio/topics/are-the-flex-6000-series-transmitters-rated-for-100-duty-cycle

     "The problem is there is no clear definition of "full" duty cycle in the ham world.  In the broadcast world, yes.  We are rated at 100% ICAS (Intermittent Commercial and Amateur Service)  ICAS implies a limited operating or 'on' period followed by an 'off' or standby period of at least the same or longer duration.  From a pragmatic standpoint, You can run "full duty cycle" modes like FT8 or RTTY all day and have no issue.  The radio will get hot and the fans will spinn up to cool the PA transistors down, but the PA in the radio is derated, so there is a lot of headroom in this regard."

     According to the Flex manual, AM should be limited to 25W.
