[TenTec] A-Meter Calibration in 3.033xa

[Kim Elmore]

I just did a careful by-ear test and Barry is absolutely correct: the 
AGC *DOES,* indeed, behave exactly as it should under 3.033xa. As has 
been pointed out here and, apparently earlier, the S-meter does *NOT* 
follow the AGC action and instead acts as if the AGC were set to "fast" 
in earlier firmware versions.

73,
