Description of the LAUR
The LAUR operates within the 
frequency band from 215 MHz 
to 250 MHz. Within that band, it 
uses a 200-kHz or 800-kHz 
bandwidth channel, 
depending on the selected data 
rate. The user is responsible for 
inquiring about local radio 
frequency regulations and using 
the frequency band accordingly. 
The LAUR unit operates from a 
10.5 VDC to 15.0 VDC power 
supply voltage. The power 
supply should be capable of 
generating a minimum current 
of 15 A. A 12 VDC battery can 
be used as a power supply. The 
power supply used shall be 
compliant with the rules and 
regulations of the FCC, of 
Canada or with other local 
regulations.
The antenna impedance to be 
used is 50 Ohm. The maximum 
VSWR measured at the 
transceiver output must be less 
than 1.5:1 at the operating 
frequencies.
