PRC-2 UHF Multi-Frequency Belt-Pack IFB Receiver
1 - 2
GENERAL FEATURES
The frequency agile IFB PRC-2 FM Receiver is designed to operate
with the ClearCom PTX-3 Transmitter and features microprocessor
control of 256 frequencies of operation within each frequency block.
Each block covers 25.5 MHz with 0.1 MHz frequency spacing. Any
one of ten different frequency blocks are factory available from 512
MHz to 805.5 MHz (except 608 to 614 MHz).
The unique microcontroller design in this receiver provides simple one
knob and one LED operation for audio level, switching frequencies
(channels), and easy on-the-fly programming. The receiver frequency
can be set by manually using the two rotary HEX switches on the side
of the unit or by using the automatic scan and store function, or both.
When powered ON, the receiver will default to the frequency set by the
switches. A nonvolatile memory can store up to five additional
frequencies accessible by pressing the knob. The memory remains
during power OFF and even with the battery removed.
The IFB PRC-2 Receiver uses 20 kHz FM deviation for efficient use of
the bandwidth and a single band compandor for clean quiet audio.
The Pilot Tone squelch locks the reception to the mating IFB PTX-3
Transmitter and ignores other signals.
The receiver operates on one 9 Volt alkaline battery for up to 8 hours
and features a tricolor LED low battery indicator. The voltages are
internally regulated for stability.
The receiver is housed in a compact, rugged, lightweight aluminum
enclosure. The unit features a durable removable belt clip and an
integral swing-aside battery compartment door.
