I am in the process of restoring a B&W 5100B transmitter and am using a Coaxial Dynamics wattmeter to measure power. I normally use this meter for CW & SSB and noticed that when monitoring an AM carrier the meter deflects downward with modulation. Is this a characteristic of this meter or maybe an issue with the transmitter itself.
