• Microprocessor Controlled Frequency Synthesiser: Allows user programmable control of scanning, channel memories and selected feature options.

• Advanced Signal Management (ASM): Identifies interference caused by strong local signals on adjacent channels and prevents these from opening your squelch. ASM also minimises distortion on reception by fine tuning the receiver frequency to match that of the incoming signal.

• Dynamic Volume Control (DVC): Automatically compensates for variations in received audio level resulting in a constant audio output level to the speaker.

• Programmable Scan Function: Scans the programmable UHF CB channels.

• Individually Programmable DUPLEX function: User selectable for only those individual channels in your area that have repeaters, leaving the others free for use as extra simplex channels.

• High Contrast Liquid Crystal Display: Fully detailed LCD provides a visual indication of the selected channel and all selected functions at a glance. Backlit for viewing at night.

• Flip Feature: Unit can be mounted with the speaker facing upwards or downwards and the display ‘flipped over’ using a simple key-press sequence to allow viewing of the display from either mounting orientation. Keys use symbols to provide readability in all installations.

• Compact Size: Fits into the smallest locations allowing installations in even the most ‘space challenged’ environments.

• CTCSS & DCS: A built-in Continuous Tone Coded Squelch and Digital Coded Squelch System option provides quiet channel operation.

• Overvoltage Protection: Special overvoltage detection circuitry protects the radio and warns of excessive voltage conditions by flashing the display.

• Surface Mount Technology: The very latest surface mount component types, design and assembly techniques and quality control procedures are used to ensure the highest performance and reliability.

• Designed and Manufactured in Australia: The TX3100 has been totally designed and manufactured in Winston Hills NSW.
