It's kinda of like the man who has two clocks....he never knows what time it is.  I suppose that maxim doesn't hold today when we have GPS clocks.

If it is a new transmitter then the direct method of E x I x efficiency is the TPO no matter what another meter says.

Now you need a third meter or method to discern which meter is the miscalibrated meter, the transmitters meters or the Bird.

You are absolutely correct!  I wish I had one to use.  I may have to ask around this part of the country to see if I can get one somehow.

The only way to resolve this is connect your transmitter to a dummy load and compare the Bird with the transmitter reading.  If there is more than several per cent difference and since you say the Bird was recently re-calibrated, I would discuss this with the manufacturer.
