Walkie Talkie VHFCOMMON FEATURES OF THE MOTOROLA GP328 PLUS AND GP338 PLUS RADIOS

ADVANCED AUDIO TECHNOLOGY
Sound quality is critical for effective communications. The GP Plus
Radio series is specially equipped with Motorola's voice compression
and expansion technology called X-PANDTM. The X-PANDTM feature enables
crisper, clearer and stronger audio quality, allowing users to continue
communicating even in noisy conditions. In addition, lowlevel expansion
enables further improvements in audio quality by reducing unwanted
background noise usually heard during pauses in conversation.LED BATTERY GAUGE
The tri-colour LED battery gauge at the top of the radio alerts the
users to recharge the battery should the battery level run low. SWITCHABLE RF POWER LEVEL
By just pressing one button, users can switch to a low power when
communicating within limited range coverage or switch to a high power
level when further distance is required. High transmit power optimises
range coverage while a low transmit power conserves battery consumption.REPEATER/TALKAROUND ENABLE/DISABLE
Users have the freedom to communicate through a repeater for wide area
coverage, or bypass a repeater and talk directly to another radio if
the coverage is within the range or when the repeater fails.TIGHT/NORMAL SQUELCH
Users have the flexibility to protect their communication by selecting
to a tight squelch to filter interference of unwanted weak signal; or
switch to normal squelch to increase coverage.LITHIUM ION BATTERY OPTION
Using the latest technology in battery chemistry, Motorola's GP Plus
series offers a Lithium Ion battery option which provides high power at
a lighter weight.PROGRAMMABLE CHANNEL SPACING (12.5/20/25 kHz)
The series allows programmable channel spacing of 12.5/20/25 kHz;
offering flexibility and easy migration of channel spacing requirements
when the need arises.GP328 PLUS 4CH
4 CHANNEL
Provides users with 4 channels to organise different work groups to meet their different communication needs.CHANNEL SCAN
Allows the user to monitor activities on different channels.SIGNALLING FEATURES
The GP328 Plus 4 channel model offers the following MDC1200 signalling:






















PTT-ID (Encode)Radio Check (Decode)
EMERGENCY "PERSONAL SAFETY" SIREN
At the touch of a button the Emergency "Personal Safety" Siren can be a activated emitting an ear piercing alarm.

PL/DPL
Private Line and Digital Private Line enables multiple work groups to be allocated to a common channel.TIME-OUT-TIMER
Will time out communication after a predetermined time, allowing channel access to more users.BUSY CHANNEL LOCKOUT
In the event of a busy channel the radio will alert the user that another person is on the channel.GP328 PLUS & GP338 PLUS SPECIFICATIONS
