External Mic Digital AGC |
(Radio Profiles, Audio Settings) |
Enables Automatic Gain Control (AGC) to be used for the radio's external
microphone. This selection
only applies while the radio is transmitting in digital mode. 
AGC compensates for differences in voice level and operational style.
As a result of AGC, audio is transmitted and then received at the same
audio/decibel level. This
selection applies to the current Radio Profile.
|
When enabled, the Radio Wide, Tx Digital / Analog Balance field must not be set to "Radio Wide", and Tx Digital / Analog Balance in the same Radio Profile record / row must be "Disabled"; otherwise, this selection is considered invalid. |
|
The Tx Gain Control Total level (also known as pure gain) is applied before AGC has occurred. For microphone input below the nominal level: actual microphone output = microphone input + Tx Gain Control Total. |
|
The Tx Gain Control Output level is applied after AGC has occurred. Tx Gain Control Output implements an infinity:1 dB ratio when microphone input is above the nominal level. That is, for any input above nominal, the output will never go above the level set via this parameter. |
