Model Numbers
The model number of the RV-M7 modem identifies its operating frequency band, rf power
level, and bandwidth. The models are:
where:
ab-c
RV-PL-
= The band (V=136-174MHz, U=406-512MHz)
a
= Sub band (A,B,C,...)
b
= Channel Spacing (blank=12.5kHz, W=25kHz)
c
Other frequency bands, power levels, and channel spacing are available. Contact the factory
for your specific needs.
