Bird meters are all over the place, especially with slugs in a humid 
environment or with dirty air. The common problem with the slug type meters 
is the calibration pot inside the slug going up in resistance.

As Terry said, the rating INSIDE the published frequency range is + or - 5% 
of full scale anywhere on the scale when properly calibrated. They do not 
roll off very fast outside the range, so the real issue on 160 with a 2-30 
MHz slug is how the slug is calibrated inside the published range.
