I will add that many operators aren't aware that their rig can't do full power
on all modes.
Many rigs rated at 100W can only do 25W in AM mode (100% duty cycle) -- the
manuals do show this.
For those rigs I always recommend to the ops to run FT8 at 50W max to avoid
pushing the temperature on their rig's finals.
So a 300 seconds Q65 would definitely be 100% duty cycle and a max of 25W or
whatever your manual says is the AM maximum power level.

Hi Edfel,
the lines in the Single-Period Decodes window without decodes indicate
the best, but not decodable, candidate signal within the current
frequency tolerance window. They may provide indication that a station
is transmitting.
As for Tx power, nothing new there, use whatever is needed to make the
QSO and not more. That could be 1500 W or 1 pW depending on the band,
path, and conditions. For EME and VHF weak signal modes like ionoscatter
a few hundred watts may be necessary. Like JT65 Q65 is 100% duty cycle
and the same considerations for PA current and temperature should be
observed as would be for any other 100% duty cycle mode like FM.
