setting is ignored. The tail time should be selected to optimise the performance of the particular
analog mobile used in a system.
General
Talk Group ID: Select or enter the Talk Group ID for Project 25 transmissions from the DMR in
basestation mode.
Unit ID: Select Unit ID for the Base-station Unit.
Power (Watts): Enter the transmit output power for the channel or click on the up/down arrows to
raise or lower the output power in 1 W increments. Because internal communication with the PA is
slow, around 30 seconds will elapse after radio startup before this setting becomes active. During
those 30 seconds, the transmitter, if keyed, will transmit at full power.
Scan Channels
A scan channel consists of two or more fixed channels. The DMR-25 will step through the list of
fixed channels until it finds one with a valid receive signal. The Channel Settings Dialog Box
displays a list of fixed channels with their dwell times. Use the Add, Edit and Delete buttons to
manage this list.
Add: Adds a reference channel to the selected scan channel list using the Configure Scan
Channel Reference Dialog Box shown in Figure 5-7. Select a fixed channel in the Reference
Channel field and nominate a Dwell Time. Dwell Time is the period, in seconds, for which the
DMR will monitor a particular reference channel given ceased activity on that channel. The selected
reference channel is then added to the scan channel when the OK button is clicked or discarded if
the Cancel button is clicked.
Edit: Changes the parameters of a preconfigured fixed channel.
Delete: Deletes the highlighted reference channel from the Scan Channel list.
