What is your PWR control set to? It sounds very much as though you have 
it set to 100W. If so, and you want less power, adjust the PWR control 
downwards to the desired power level.

The IMD in PSK31 at 100W output is about 10 dB worse than at 50W, 
according to measurements made with my KF6VSG PSKmeter. IOW, in PSK31 
you will have a cleaner signal at 50W than you do at 100W.
