    Blown final transistor? Sometimes the "pre-driver" will still function depending on the failure in the final transistor and give you about a 1/2 watt output. Meter will not move much but a radio in near proximity will still hear the radio with the blown final just fine.

    Might start with a wattmeter in line with the antenna. Gonna guess you don't have a test ("dummy") load handy.

    Seeing what actually comes out of the antenna jack when you transmit would be a good place to start.
