Which tuner are you trying to tune? The internal tuner in the F3K or an
external tuner?
The reason higher power levels are allowed when tuning is some external
ATUs and amps need more than 10 watts.
We also use TUNe at 100 watts into a dummy load to verify the PA maximum
output without have to hook up a key in CW mode to do it.

Something odd happened today.
I am running a Flex 3000. I was at 28.457 and trying to tune up the
radio to my antenna with my tuner. I had just tuned successfully
just a little off this frequency and was just touching up the tune.
I pressed the TUN button in Power SDR, and it totally locked up and
continued to transmit. The only way I could make it stop was to use
ALT-F4 to close Power SDR (version 2.2.3), or to turn off the radio,
which, of course, crashes Power SDR. I tried changing the frequency,
and it worked flawlessly on all other bands, and also on this band
without any lockup, EXCEPT between 28.4558 and 28.4575 where it
consistently locked up Power SDR.
I finally tried reducing the tune power from the 50 watts my copy of
Power SDR to 10 watts, and it seems to have made the problem go
away. I do not recall changing the default tune power to 50 watts,
and now wonder why it is variable if it can cause Power SDR to lock
up. I see that the screen capture in the manual shows it set at 10
watts, but why is it allowed to be changed? What else is TUN used for?
