Firmware dictates lower power output

[K7VO]

I liked it when my K3 would put out 120 watts and it had no problem with PA temp. Now it is limited to 100 watts due to the firmware upgrade. Am I able to adjust the power output back to the higher level? What is the procedure? If I shouldn't do it then why not? Great radio!

You'll probably get a lot of this, but why do you need 120 watts? Anything above 100 watts the transmit IMD starts to degrade. It's bad enough at 100w for 12volt finals.
