[TenTec] A-Meter Calibration in 3.033xa

I use a 565, not a 566, but my understanding from previous discussions was
that the slow AGC in the latest firmware WAS slow in its receiver gain
control and it was only the s-meter action that was fast.  The fast s-meter
was throwing everybody off - listen with your ears for slow gain control.
I could be wrong, but I seem to remember John Henry weighing in with that
info.  If true, that means it's not a bug.
