Are the Flex 6000 series transmitters rated for 100% duty cycle operation?

    My 6600M when set to 100 watts puts out 30 to 40 watts max when driven in DIGU mode for
    FT8 and Audio is in Yellow Zone and not overdriven into the Red Audio Zone
    In Green Zone the 6600M output is between 15 to 20 Watts output for me

    No problem running FT8 or RTTY at 100W output on my 6500. If you run for a long time, the fans go to high speed and make a racket. Flex more or less says this is safe. The Tx will shut down if it really gets too hot. As to "official", ham gear usually has lots of parameters that aren't specified or fully guaranteed. Flex gear is advertised as 100W output, and that's what I get.


    @mikeatthebeach: Check your audio and/or processor levels?

    100 W should be possible with single tone modes like FT8, CW, RTTY, etc. (But don't try it for PSK31 or multi tone modes that need linearity.)

    Ft8 is a high power low signal mode.
    Yes, the radio's are designed for 100% duty cycle.

    We're all supposed to use only the power necessary to communicate. With FT8 or any other mode, that could be a mW or a kW depending on conditions. FWIW.
