Digital/analog Dual Modes
BF-TD872 gives you a smooth transition from the analog world to the digital.
A Longer Battery Life
BF-TD872 can function for longer than any conventional analog radios. (digital 17hours; analog 13 hours)
Excellent Audio Quality
Excellent digital audio quality comes from the AMBE+2TM vocoder and FEC technology
Radio Priority-Based Interruption
This function enables a radio with higher level to interrupt communications between radios with lower levels, giving higher priority to radios with higher levels. This means better dispatching efficiency.
Scan/Monitor(Programmable)
At a convenient push of a button you can monitor all the conversations on your channel or you can scan conversations on different channels.
Private Call, Group Call And All Call (Programmable)
The versatile calling functions bring more efficiency to your teamwork.
DMO Pseudo Trunk
The user can choose slot 1 or slot 2 for communications. When one slot is occupied the radio will automatically switch to the free slot. Frequency efficiency is greatly 100% increased.
