Tom,

First, what's your reflected power.  Second, I don't own that radio but your 
rig my be auto tuning the power down because you are testing it in the RTTY 
mode which doesn't want to run at 100 watts continuous duty cycle.  That 
happens to me in the AM mode checking power out.  A CW carrier works the 
best.

Phil.
