Jim,
Is this being measured into a known 50 ohm load? Or is it a tuned circuit of some sort?
If the load is somewhat reactive at certain freq. or if the coax connecting the meter into the circuit has an issue with certain freq. then it is very likely to attain the different readings on a wattmeter.
