[Elecraft] Bird 43 Wattmeter calibration

[Stuart Rohre]

There are no user adjustments on the slug or pickup of the Bird that I am
aware of.

You could check it against some other known standard and construct a graph
paper of differences, but the Bird is good plus or minus 5 per cent about as
good as it gets for RF unless you go to high dollar calorimetric measuring
devices.

Check the Bird web site and see what they say about user calibration or not.
The whole idea of a Bird, is a mechanically robust pick up and fixed slug
that plugs in and out.

Now the meter might get off, but that too is mostly rezeroing the mechanical
zero stop.
