Please note that the setup is the same for all reflectors except for a small difference 

in DMR, when you select a reflector there is no port.   Since there are lot of them the 
port selection is changed by using different increments (step) to navigate through the 
reflectors.  See the image below. 

 

 

 

 

Transmitting with the DV4home

 

 

The DV4home operates like a normal transceiver without the RF.  It has two 

separate IP transceivers (2 x AMBE chips) so you need to select which one you will 
be using; this selection is similar to switching the microphone between two different 
active VFOs or bands on a RF transceiver.   Depending on your choice it will transmit 
on the active reflector connection for that mode. 

 
The * after the mode indicates the current active mode. To change modes on the 

main screen, just press and hold the MENU knob then it will switch the mode.
