The ProTalk TK-3401D is a license-free UHF digital transceiver featuring digital dPMR446 and analogue PMR446 communications.
The TK-3401D features the latest digital dPMR446 technology for better radio interference protection. It'seasy to switch between digital and analogue modes, with a total of 32 channels (16 digital and 16 analogue) in two zones, which is ideal for use with current analogue transceivers with a view to gradually switching to digital.
Built-in voice-inversion scrambler
The voice-inversion scrambler provides basic protection against casual eavesdropping.
Digital technology’s lack of residual noise produces clear, crisp audio quality
Upper Residual noise in analogue mode drowns out voices, making it hard to hear. Lower The lack of residual noise in digital mode delivers clear, crisp communications.
DSP delivers high-quality audio with minimal delay.
The high-quality audio design draws on Kenwood's state-of-the-art technology and features a DSP withan AMBE+2 vocoder. Optimized DSP internal processing also minimizes the delay associated with digital voice audio.
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.
A High-Capacity battery for long-lasting operation
The TK-3401D comes with a high-capacity 2.000mAh Li-Ion battery to deliver up to 24 hours of operation. The ability to keep going with no battery replacement means better reliability even in harsh working environments.
254 common ID codes (Digital Mode)
The pre-programmed QT tone frequencies can be changed for each channel. The TK-3401D also offers DQT for a quiet standby mode.
Compatible with QT/DQT (Analogue Mode)
You can change the pre-programmed QT tone frequencies for each channel. The TK-3401D also offers DQT for a quiet standby mode.
