Signalling Features
The GM328 offers the following signalling features:
MDC1200 PTT-ID encode
MDC1200 Selective Radio Inhibit decode
DTMF PTT-ID encode X-PAND(TM) Audio Technology
Motorola's special voice compression and expansion technology called X-PAND enables crisper, clearer and stronger audio quality, allowing you to keep communicating in any noisy environment.
Switchable RF Power Level
The transmit power level can be adjusted to accommodate the users environment. Thus, minimising the risk of interference with other systems.
Repeater/Talkaround Enable/Disable
Freedom to communicate via a repeater for wide area coverage; or bypass a repeater and talk directly to another unit for easy local unit-to-unit communications.
Optional Voice Storage
Through an optional voice storage board, the GM328's capabilities can be expanded to the recording and playing back voice messages or personal memos for up to 120 seconds
Voice Operated Transmission (VOX):
For hands-free operation, activate this option using visor microphones.
Programmable Channel Spacing of 12.5/25kHz Mode
Flexible and easy migration of channel spacing requirements in any situation.
External Alarm
Activates the vehicle horn and/or lights on receipt of an incoming call, so you won't miss a call even when away from your vehicle.
Public Address Mode
This feature allows you to use your radio audio as a public address system simply by adding an external speaker and switch fitted and programmed by your dealer.
Data Capable
A modem can be fitted inside a special expansion head, or external to the radio.
Additional features
Single priority Scan (channel scan)
Remote mount capable
COSMETIC CONDITION:
Excellent, however it should be noted that the previous owner has etched their ID into the top side of the case
TESTING:
Powers up fine, self test passed.
Only Channel 1 is programmed at the moment, it transmits on 450.125Mhz
Channels 2-3-4 all produce a low frequency tone when selected, this means they are not currently programmed.
I do have a FULL service manual which might be useful in the future but it will not help with programming this equipment.
Programming accessories and information to reprogram this equipment are relatively easy to find on various sites online.
