The 700/800 MHz XG-25M radio is aligned for a maximum transmit power of 35 watts
across the entire 700/800 MHz frequency band. However, FCC licensed systems, verify
the radio’s 700 MHz channels are limited to 30 Watts or per license requirements via the
radio’s personality programming.
The UHF XG-25M
radio is aligned for a maximum transmit power of 50 watts across its
entire 378 - 470 MHz operating band. However, f
or equipment operating in accordance
with FCC 47CFR80 rules (i.e., Maritime Services), it is the responsibility of the licensee to
ensure the radio is installed and aligned per license requirements.
