[Elecraft] PSK31 question

What I do is to set the power for 5watts in qrpmode and adjust PC to the 
point where output just drop a little bit.
I think this will be almost the same as set power for 10 watts and adjust 
pcoutput for 5watts.
Somehow I have never liked the second method because I like to limit my TX 
the hard and secure way.
Some also advice to set tone for psk31 to a frequency so high that harmonics 
is outside the passband the ksb2 is capable to send in.
If you have basic KSB2 you could set tone to 1200-1300hz.
Harmonics will then be attenuated.
But I have tried to send 1000hz tone with 5watt setting and pcoutput just at 
droppoint.
Nothing sounds wrong on other rx in schack. No harmonics.
