The radio setup requires setting the modem configuration options and also 
setting the radio frequencies.  The modem configuration options are accessed on 
the Radio tab of the Modem Configuration.  The frequency programming is 
accessed with the Frequency Configuration button on the main screen of the 
configuration program. 
 
 
The radio configuration options set the operation of the radio.  These 
configuration options are set using the Radio tab of the Modem Configuration 
portion of the configuration program.  
 

 

 
Selection Description 
Occupied 
Bandwidth 

The occupied bandwidth sets the amount of frequency 
bandwidth that the transmitted signal will use.  A higher value 
corresponds to more bandwidth and therefore provides better 
BER (Bit Error Rate) performance. 

The occupied bandwidth must be set to equal to or lower than 
the occupied bandwidth that is allowed for the channels in 
use.   

GMSK (BT=0.3) 

Gaussian Minimum Shifted Keyed modulation with a BT = 
0.3. 

This is more spectrally efficient than GSMK (BT=0.5) 
modulation.
