13 seconds of transmit, 17 seconds of receive = 43% duty cycle.

I use (rarely) less than 100 watts, all the way up to band legal limit.
With a K3, don't worry about it.  IF the cooling become inadequate due
to local environment, it'll reduce output to protect itself.

Hi all,
I'm leaving for VP9 on Wed, and taking my trusty K3.
A little time will be devoted to FT8 so my question is what is the duty cycle 
for running FT8 on K3?
I've read a couple old posts about PSK, so I'm wondering what the group is 
doing.
How much power out are you running the K3 on FT8 without overheating etc?
