3.5. Model Numbers
The model number of the FireLine modem identifies its operating frequency
band, rf power level, and bandwidth. The models are:
RV-M5-
ab-cd
where:
a
= The band (V=136-174MHz, U=406-512MHz)
b
= Sub band (A,B,C,…)
c
= Channel Spacing (N=12.5kHz, W=25kHz, S=25kHz SkyLine compatible)
d
= Power output (2=2 watts, 5=5 watts, 1=500mW)
Other frequency bands, power levels, and channel spacings are available.
