Saw another of your posts and see that the 480 you have is the 200 watt 
version, so no internal tuner.   I know everybody tried to warn you away 
from going that route, but since you went with the 200 watt model, you 
really need to do a better job on the antenna matching or you will smoke 
this one too.  If 100 watts gives a whiff of  smoke, 200 watts will  be 
a bit more pungent.
