The new Kirisun TP-660 UHF DMR handheld transceiver will deliver superior communications for all of your Amateur (HAM) or Commercial/Business  radio DMR needs in the most extreme of environments . The TP-660 provides crystal clear DMR digital audio for both your local and DX DMR QSO’s.

The TP-660 is ruggedly built and has been designed to meet both IP55 and MIL-810C/D/E/F/G standards

DMR’s two time slot transmission system reduces your transmit time by half and in turn provides you with longer talk time. The 2000 mAH Li-ion battery included with the TP-660 gives you 14 hours of operating time using standard analog FM mode and 16 hours of operating time in Digital DMR mode.

Crystal clear DMR digital audio is achieved using the AMBE+2 vocoder, which will provide consistent excellent digital audio throughout your favorite repeaters coverage area with no noise or fading even in low lying areas. The TP-660 has a powerful 1.6 watts of audio of output power to insure loud crisp receive audio.

• Rugged Design: TP660 is strictly designed to meet IP67 and MIL-
  810C/D/E/F/G standard, ensuring good performance in potentially harsh environments such as harbors, manufacturing plants, construction sites, and etc.
• Durable Battery: Two-time slot transmission reduces transmit time in half and thus increases talk time longevity. 2000mAh battery supplied in standard package ensures at least 14 continuous working hours in analog mode and 16 hours in digital mode
• Improved Audio Quality: Digital error-correction technology rejects noise and static, providing consistent audio quality throughout the coverage area and even in challenging low-lying areas. 
  Utilizing DVSI's AMBE+2 vocoder further improves speech communication. 1.6W audio output and a 40mm diameter powerful speaker ensure louder and crisper voice communication.
• Higher Channel Capacity: TP660 can work with a single repeater to achieve twice the traffic capacity without re-licensing or re-banding, meaning two voice communications or one voice communication and one data transmission can transmit at the same time in one channel.
