Main Features


This function is used for audio encryption, which can further secure the safety of communication, and those radios without this function are unable to receive real audio.

VOX Earpiece

If VOX (Voice-Operated Transmit) is programmed in your radio, you can communicate through your VOX earpiece to enjoy hands-free operation.

Battery Strength Indicator

Just through a key-press, you can enjoy the convenience of knowing the current battery strength from the color of LED indicator, which accordingly throws away your trouble on the specific charging time.

High/Low Power Switchable

For each channel, the power can be adjusted through the key pre-set as High/Low power switch. When the communication range is small, low power is of priority for battery saving.

Programmable 25 KHz /12.5 KHz Channel Spacing

For future adaptability, users can program the TC-320 channel spacing as 25KHz or 12.5KHz through programming software, no need to buy a new radio.


This function is especially useful when receiving weak signal. Hold down MONI key, the activity in current channel can be monitored.

CTCSS/CDCSS and Squelch Tail Elimination

38 groups standard CTCSS and 83 groups standard CDCSS available. If your radio is set with CTCSS or CDCSS, both the interference from the same frequency and the squelch tail from communication termination or carrier disappearance can be eliminated.

Channel Scan

When scan is enabled, press the side key to start quick scan for all the channels in the scan list. The scan will stop or pause at the channel where a signal is detected.

Auto Battery Save

Radio enters “Battery Save” mode when no signal is received or there is no operation on the radio. This can prolong the battery life through lowering the battery consumption.

Low Battery Alert

Radio will alert users to charge the battery when it runs low.

Busy Channel Lockout(BCL)

BCL can prevent radio from receiving any unconfirmed signal and transmitting signal to any busy channel, keeping the channel clean and free of interference.

Time-out-timer (TOT)

This function is used to avoid time-out occupation of a channel. TOT restricts the maximum duration of each transmission, which not only can realize battery save and reduce the channel block time, but also can avoid the probability of channel occupation because of improper operations.

PC Programmable

This function enables users to program the radio’s frequency and other function settings without disassembling it.

Wired Clone

Users can clone the function parameter of a radio to another radio through the clone cable, requiring no PC programming operation.
