6600 Transmitter Duty Cycle?
What’s the duty cycle rating of the 6600’s transmitter? Can I run 100 watts in a 100% duty cycle mode like RTTY indefinitely, or is there a time limit?

Thank you. That's disappointing.
@Pete La Is that true of the Flex 6000 series radios? Some radios and some amps require reducing power as you describe, but I do not see anything about that in any of the Flex documentation. Have I missed something?

My Alpha amp can run legal limit output indefinitely. You may remember their ads in the ham magazines? The ones with the brick on the key? They used to do this at big hamfests too--they'd set up the amp on a table connected to a beefy dummy load, and put a brick on the key and it would run this way all weekend.
IMO, advertising a rig as having 100 watts output should mean that it can run 100 watts indefinitely. If it can't, it should say so in the specifications.
Temperature is the controlling factor for the radio. It can be monitored with multiple software products, like the meter from K9DUR, but the radio will shut down before damage occurs. For some applications, continuous operation is required, but for ham radio, like most two way communications transmitting is not continuous, since listening is required. So most specs say “ICAS”, intermittent commercial and amateur service. FT8 is among the most demanding with a 50% duty cycle. I have run FT8 for up to an hour into a dummy load. The fan speeds up, but the 6400 keeps going.
