Uniden BR330T Hidden AGC menu useful?

[RedPenguin]

I was wondering if anyone had any real experience with the 1.3.06 Firmware's new AGC hidden menu. Does it work well and are there any settings that make the scanner basically perform much better?

Also, speaking of AGC, does it really do anything? I don't seem to notice that much change with or without AGC.

It works the same as the 396 analog AGC version. You won't really hear the difference on short bursts of audio (voice), with the exception of tones being quickly reduced in volume, but on long voice comms I notice a change.

It works very well for me, the best thing to do is to tune into a channel on hold while in the AGC hidden menu and see how the settings effect the AGC, quality, volume etc. Once you figure out the best settings you will wish all radio scanners had this (along with dynamic memorys).

Sorry for maybe dumb question, but what is AGC menu and where is it hidden?
Just curious.. I have new firmware upgraded.

The link above is not for the BR330T.

That link is the procedure for tweaking the AGC digital/analog settings for the BCD396T and BCD996T.

And those directions do not apply to the 330, its not digital..

This is the procedure for the 330


Adjusting AGC Parameters (Unofficial)
This setting is neither fully tested nor supported by Uniden America Corp.

ATTENTION!
This change allows access to some AGC parameters that might result in poor audio. The default settings of 0 have been arrived at through testing in multiple environments. The use of other settings is at your own risk. Uniden America Corp. is releasing access to these features without support.


General Notes:
• All settings are saved, even when you cycle power and the option is no longer available.
• These settings are not accessible through UASD.
To access these settings:,
1. Press [HOLD] while turning on the scanner.
2. Tune to an analog channel.
3. While receiving a signal, hold F then tap the scroll knob. The scanner displays the current RES TIME parameter setting (see below for option details).

4. Rotate the scroll control to change the setting.
5. F+rotate the scroll to select another setting.

Parameters:
RES TIME
Range: -8 to +8 (0 is default)
This parameter determines how frequently the AGC factor updates. Decreasing this value makes AGC respond faster, but could result in “pumping.” A higher value decreases the response time.

REF GAIN
Range: -5 to +5 (0 is default)
This parameter determines the reference level that AGC attempts to adjust the volume to. If digital/analog volume is not matched, adjust this parameter.

GN RANGE
Range: 0 to 15 (0 is default)
This parameter controls the total dynamic range of the AGC adjustments. A larger value allows a wider variation in volume.
