Is this all bands? All modes? Can't you get the swr lower than 2:1?
The 480 manual suggests 1.5:1 or better. High swr means power
foldback to protect the finals.
Be sure all coax connections are tight. Try into a dummy load if you
have one. Check mic gain/processor levels for ssb, or carrier level
for cw/rtty. Sometimes things get put out of adjustment by accident.
