Main Features

Sixteen RF Channels & QT Tone Keys
These compact and easy-to-use VHF/UHF portables are available with sixteen RF channels. Each RF channel can beassifned a Quiet Talk (QT) tone key to eliminate unwanted signals. This helps to minimise interference from other users as audio will not be heard if your radio receives a signal with the incorrect tone key.
Wide/Narrow Channel Bandwidth
the TH-2107/3107 can be programmed for wide or narrow bandwidth operation pre radio to accomodate all present and future channel allocations.
Rock-Solid Design
The TK-2107/3107 is your guarantee of absolute performance in demanding situations as it fully complies with MIL-STD 810 C/D/E standards for resistance to shock, vibration, humidity, dust, and rain. The alluminium die-castchassis, sealed case design, and SMA antenna connector withstand rough handling to enable these exceptionally rugged radios to provide years of reliable service.
Time-Out Timer
When the preset continuous transmit limit is reached, the time-out timer automatically switches the TK-2107/3107 to receive operation. This limits per transmission talk time of each unit to help reduce channel congestion and conserve battery power.
Battery-Saver
This feature automatically puts the radio in "sleep" mode to conserve power when it has been in standby mode (no transmit or receive) for more than the present limit.
Two-Colour LED
For added convenience, the two colour LED indicator lights red for transmit and green for an active channel.
Low-Battery Alert
The flashing red LED indicator warns you when the battery should be re-charged.
