Flip the High/Low switch to Low. That amplifier should tolerate closer to 1.5 Watts of carrier. That radio is too big to run this amplifier on "High". That setting is for smaller radios that have only a single final transistor. Your radio is almost twice as large as this amplifier needs to drive it full-bore.

For that matter, a coax jumper with a poor ground connection on one end can do something like this, too. Watching the radio's SWR meter while flexing the coax jumper could reveal that.
