DR Receiver Channel Monitor View

This is the place to monitor channel activity when connected to receivers.

The view can be used in two ways. The first is to show all channels for all frames in the session. To do this, select the Session icon in the tree view.

All channels in the session are shown in a tabbed view with channels divided into groups depending on the screen size and zoom level of the application. In this combined view they are numbered as channels 1 - 12.

The second way is to show only the channels for a single frame. To do this, select a frame icon in the tree view.

All channels for the selected frame are shown in a tabbed view with channels divided into groups depending on the screen size of the application. In this single frame view they are numbered as 1 - 6.

To configure channel settings, double click a channel to open the Edit Channel Settings dialog.

Name, Block and Frequency

This LCD style indicator shows the channel name, frequency block and frequency of operation.

The channel name font size can be changed. To do this, right click, and choose the Channel Name menu item.

Select a font size from the list.

In this example the size has been changed to Large. The frequency block information no longer appears.

RF Link

This LED style indicator lights blue when an RF link is established, meaning that a signal is present and is being successfully decrypted. The LED blinks when a signal is present but decryption is unsuccessful.

Use this indicator to verify that the transmitter has been programmed with the correct encryption key.

Signal Strength

This meter shows the received RF signal strength. There are 3 different RF meter types available.

The color is green if the RF Link is good and audio is unsquelched, yellow  if the RF Link is good but the audio squelch is active, and red if no RF Link is established. In the strip chart example you can see a brief dropout in the history during which the receiver audio was squelched.

Receiver Audio Level

This meter shows the receiver audio level in dB relative to the threshold of limiting in the transmitter.

The bars light green for transmitter audio levels below the threshold of limiting for the limiter following the mic preamp. The LIM bar will light yellow  when the transmitter audio level exceeds the threshold of limiting.

This meter can be used to verify that the transmitter mic gain has been set properly. The gain should be set so that the LIM bar lights up on voice peaks.

An audio meter Peak Hold feature is available. To use it, right click on the Session icon in the tree view and choose Audio Meter Peak Hold from the popup menu:

Select Set Peak Hold to enable the feature. When done, select Clear Peak Hold to restore normal operation. This setting applies to all audio meters in the session. The peak hold function includes limiter and clipping indications.

Receiver Audio Clipping

This LED style indicator lights red when the receiver audio has reached the clipping level.

This indicator can be used to verify that the receiver's audio output level has been set properly. This indicator must never light up during operation.

Receiver Antenna Diversity

This icon style indicator shows the instantaneous antenna diversity status. Either antenna A or antenna B will be indicated as the favored antenna.

This indicator is be used to monitor the diversity status when the channel is in use.

 

Receiver Mute

This button is used to toggle the mute state of the receiver audio.

 

The button turns red when the audio is muted. Also, the bezel turns yellow.

Transmitter Battery Status

This icon style meter indicates the state of charge of the transmitter batteries and the current terminal voltage.

The state of charge is shown as a percentage of full capacity. As the batteries run down, the color of the meter changes:

Note - If the Show Battery Time option is enabled the elapsed time will be displayed instead of the battery terminal voltage.

 

 

 

Transmitter Mute Status

This icon style indicators shows the mute state of the transmitter audio.

The indicator turns red when the transmitter audio is muted. Also, the bezel turn yellow.

Warnings and Alarms

The bezel around a channel control changes color to indicate trouble or that audio is muted. In the tree view, the same color is applied to the channel in the frame icon.

Zoom In/Out

Use the key combination Ctrl-Plus to zoom in, Ctrl-Minus to zoom out.

The view will adjust to show as many channels as possible for the zoom level. Here the view has been zoomed out to see all 12 channels in the Session.

Tip - If you have a touch screen, two-finger zoom in and zoom out gestures work also.

 

 

Hide Empty Channels

Not all frames are fully populated with modules. When empty channels are shown they are marked as "Not Present".

To hide empty channels, choose View->Hide Empty Channels When Connected from the Main menu.

Now only the six channels actually present are shown. Use this option for a more compact view focused on installed channels only.
