The ProTalk TK-3701D is a license-free UHF handheld radio for both digital dPMR446 and analog PMR446 communication. This radio allows for combined digital and analog operation, enabling the reception of both digital and analog signals within a zone. This facilitates a gradual migration, allowing continued use of existing analog radios until a full transition to a digital system is made.

The TK-3701D features modern digital dPMR446 technology across a total of 48 pre-programmed channels (32 digital and 16 analog) in 3 zones (2 digital and 1 analog). It is ready to use right out of the box and comes with a rechargeable battery, charger, and belt clip. If you are looking for radios for communication over shorter distances, the TK-3701D is the ideal choice.

Digital means better communication. When the radio is in digital mode, users hear incoming signals clearly. Transmission delays are minimal, as the radio is equipped with a DSP and an AMBE+2 vocoder. The TK-3701D features a large internal speaker and a BTLAudio amplifier, ensuring clear communication even in noisy environments. With 1 W of audio power, it guarantees a full sound.

As the RF signal strength decreases with distance, analog signals become increasingly noisy or are received with interruptions. The digital modulation of dPMR446 technology improves reception quality even in fringe areas, resulting in approximately 20% greater coverage compared to analog PMR446.
