The columns were scrambled in my post

[garyrc]

I see that the three correction charts I just posted have well scrambled columns. Apologies to all, particularly to Mike Lindsey, because his chart is misrepresented in the scrambled columns.

For those who may be interested, I'll write the data out linearly. For the following 1/3 octave points of 5K, 6.3K, 8K, 10K, 12.5K, and 16K:

My reading of Radio Shack's free field C wtd graph, the compensation needed would be -4 dB, -5 dB, -4.2 dB, -3 dB, -1.8 dB, +1.2 dB. The corrections I measured on the Rives CD for the RS Meter are -1.3dB, -1.1 dB, -2.1 dB, -1 dB, +0.5 dB, 0 dB. In Mike Lindsey's post, he recommends 0 dB, +2 dB, +3 dB, +4.4 dB, +6.2 dB, + 8.5 dB
