Power output changed in K3

Hello Elecrafters,
I recently discovered that only 20m can deliver 90W with all other bands deliver 40-50W. I did a RF power output re-calibration and everything is ok now.
I don't know why this happens? I did not do any changes in configuration before.
Any ideas?

Re: Power output changed in K3

Did you load one of the recent beta firmware releases? Starting with
5.01 (I think) - certainly in 5.10 there was a change that required
redoing the TX power calibration.

Yes. Note with 5.10 says " /Those who loaded rev.
5.10 must re-do the 50-Watt gain calibration."

/Guess I'd better do that today :-)

There's are 3 calibration levels in the Utility. 50Watt, 5 Watt and 1
milliwatt. Do all 3 of them and you should have it covered.

Re: Power output changed in K3

The only "special tool" is a dummy load on the low power output jack.
K3Utility does the rest.
