RX Mute During TX Voice Delay
If
TX Voice Delay
and
RX Mute During TX Voice Delay
are enabled, then no receive
audio is heard by the console while it is transmitting. This is meant to mute the radio’s
progress tones including the go-ahead-to-talk beep emitted when a channel is acquired.
This beep is meaningless to a console operator, since they are able to start talking
immediately upon pressing the TX key. Call failed tones are still received by the console.
If the check box is not checked, all radio progress tones are heard by the console
operator, assuming the console is configured for full duplex operation. The default is
checked.
Peak Level From Console (dBm)
Note
The parameter listed here as “Peak” Level is also referred to as
High Level Guard Tone or HLGT in other places.
Peak Level From Console
specifies the level at which high level guard tone, from the
console system, reaches the iRIM. It must account for any line losses between the console
and the iRIM and is expressed in dBm. A value of 0 dBm is equivalent to 0.775 VRMS.
The default is
10
dBm.
Audio Level From Console (dBm)
Audio Level From Console
specifies the level at which average voice audio, from the
console system, reaches the iRIM. A 1 kHz tone at this level is sent over the air at 60%
channel deviation. This level must account for any losses on the line between the console
and the iRIM and is expressed in dBm. A value of 0 dBm is equivalent to 0.775 VRMS.
The default is
-7
dBm.
Audio Level To Console (dBm)
Audio Level To Console
specifies the level at which average voice audio, sent to the
console system, leaves the iRIM. A 1 kHz tone at 60% channel deviation received from
the radio is sent down the line at this level. This level is not affected by losses on the line
between the console and the iRIM and is expressed in dBm. A value of 0 dBm is
equivalent to 0.775 VRMS. The default is
-7
dBm.
Audio Termination From Console
Audio Termination From Console
determines the termination applied to the transmit
audio sent from the console system to the iRIM. It may either be set to 600W or 200 kW.
Typically, only one device on the line would be terminated at 600W, while all others
would be set to 200 kW or some other high impedance. The default is
600W
.
Guard Tone To Console On COR
This parameter is not used.
