For PSK-31, you really want to run the minimal amount of power necessary.
Remember that the entire PSK-31 subband fits in your receiver filters --
you don't tune the VFO at all.
If you transmit a strong signal, and propagation is good, I'll be able
to work you, but when my receiver AGC cuts in all the rest of the PSK-31
stations on the band will go away.
If I happened to be working one of those other stations, my QSO is over.
As a rule of thumb, you don't want to exceed half the output power,
unless the amp is rated for 100% key down. Monitor the temperature.
50 watts is a lot of power on PSK-31.

I just ordered a KPA100 with the auto tuner for my KX3. In anticipation of the
arrival of the amp I was looking at the operating manual online and did not
see any recommended power setting for operating the amp with digital modes. I
plan to use the amp for PSK31. What is the recommended max power setting for
the amp using PSK31 with a KX3?
Thanks,
