AGC???????
It is not AGC is is AVC "Automatic Volume Control" because for FM and Digital transmissions they are for the most part immune to variations to incoming signal levels.
So here is my philiospy.
I have 396XT, 996XT, BCT15X, HP1, 436HP and 536HP radios.
With the exception of the HP1 and maybe the BCT15X there is only an AGC "On" or "Off".
The x96XT and the x36HP have far more sophisticated "AGC" settings for both analog and digial and many settings for each, not just a basic "On" or "Off".
I have looked over the instructions for operation and configuration of the "AGC" on these radios also looking for examples and a CLEAR and OBVIOUS explanation of how each setting impacts performance and what some of the basis/default settings should be with CLEAR and OBVIOUS examples.
I see things this way, if the "AGC" actually worked and was fully implemented on thee radios the instruction manual would have a lot of detail, likely 6 or more pages on "ACG" operation and configuration.
I have put out a challenge for anyone to offer proof the AGC works on any of these radios with examples of what settings they are using and even explain if they have the AGC working what each setting likely adjusts.
Given the Volume Offset actually works and it is a nice feature for many reasons, one would assume that the AGC actually utilizes the same components for the Volume Offset. This also means there should be some form of detection circuit to determine when a TG or Channel Volume level is too great and then attempt to level the Volume.
I have also suggested that Uniden put together a White Paper description of how the AGC works, what each setting does and how it impacts the AGC performance and some examples for default setting to start with and how to "Fine Tune" the AGC.
So far I have not been successful in getting the AGC to function and maybe it is because I am not going to waste my time finding out it does not work and also playing with many, many combinations that are undocumented.
This is just a total fail on Uniden's part.
So I challenge Uniden to prove to the user community the AGC works and document how it works and how to use it.
