HIGHLY EFFICIENTAND STABLE OUTPUT
POWER
Icom’s expertise in radio technology has produced the
IC-RP1520, an FM repeater highly efficient and com-
pletely stable with a PA module used in the transmitter
output circuit.
POWER SUPPLY SYSTEM
The repeater has two-way, AC and DC power source
capability. If AC power to the repeater is interrupted,
DC power can be automatically connected as a backup
s o u r c e .
DUTY POWER SUPPLY
A heavy duty power supply unit is adopted to follow
load fluctuations and secure continuous 24-hour opera-
tion.
REMOTE CONTROL SYSTEM
With an external receiver and the built-in DTMF tone
decoder, it is possible to control user-programmable
functions. To prevent functioning errors, a 4-bit
password is available to control them. The following
functions can be remotely controlled from the control
operator.
Tone squelch function ON/OFF
Tone encoder function ON/OFF
