Compatible with digital or analogue

This radio allows Digital and Analogue combined operation, which means it can handle both digital and analogue signals in a zone. This gives you the freedom to migrate at your own pace — whether you are ready to go fully digital, or use with the current analogue transceivers with a view to gradually switching to digital.

No licence required

The TK-3701D is a licence-free dPMR446 and PMR446 UHF digital transceiver. The ready-to-use package comes with a transceiver, rechargeable battery, battery charger, and belt clip. If you are looking for a radio system that covers only small areas without the need for a repeater, the TK-3701D is an ideal choice.

Selectable 7-colour LED*

A large 7-colour LED indicator on the top panel illuminates to notify multi-status functions including power-on and different unit identification.

*PC programming required.

Clear and powerful sound output

  • Digital means clear, crisp audio quality
    When the radio is in digital mode, the user can hear clearer sound with less residual noise. Delay associated with digital audio can be a drawback at times however such delay can be minimised as the radio features DSP with AMBE+2™ vocoder.
  • BTL audio amplifier for powerful 1W output
    Operator’s usage environment can be noisy at times however with the large internal speaker combined with a BTL audio amp, the radio can deliver up to 1 watt of clear sound.

Digital technology provides superior clarity in extended coverage

As RF signal strength weakens with distance, analogue reception becomes increasingly noisy and intermittent. dPMR446’s digital modulation technology improves reception in fringe areas, thereby “effectively” increasing coverage as much as 20% compared to analogue.


IP54/55 and US MIL-STD 810 C, D, E, F, and G standard-compliant

Compliant with 11 US military standards (MIL-STD). IP54/55 protection against water jets is also featured on the TK-3701D*.

*All interfaces must be fully sealed with appropriate covers or by designated genuine accessories.

A High-capacity battery for long-lasting operation

The TK-3701D comes with a high-capacity Li-ion battery to deliver long hours of operation. The ability to keep going with no battery replacement means better reliability even in harsh working environments. Besides the supplied Li-ion battery, optional rechargeable batteries and other accessories that can be used with the TK-3701D are available.
